    Tape & Vinyl at center stage in The Lab


    2016 - 05.23

    Recently I decided to take some glamour shots of my stereo setup in “The Lab” and post them to a vintage audio usergroup for others to oogle and discuss. Some of the elements shown here have already been written about individually so I won’t recap that (get it?) in detail here. Clicking on any image will enlarge it, then right click again on the enlarged image if you want to see if in 100% resolution.  Below is a list of the components and links to more descriptive posts on these where available:

    The Cast of Characters:

    Speakers: Marantz HD-770
    Amp: Fisher CA-2310
    Turntable: Marantz 6100
    Reel to Reel: Ampex 960

    The Leslie Model 205 and Electric Trumpet v3.5


    2016 - 01.27

    I’ve made several tweaks to my electric trumpet setup over the last few months and I’m feeling fired up about the results. Most notably, I managed to score a Leslie rotating speaker off Craigslist, which is a rightous acquisition on many levels. I’ve been at many live shows and studio sessions that used a Leslie for organ amplification and having stood next to one, I can attest that although there are many rotary emulations and good quality recordings of rotating speakers out there, there’s simply nothing like being in the room with the real thing. There’s a rich 3D quality when you hear it in person that needs to be experienced in realtime. For a long time I’ve always thought it would be so cool to have one, and now it’s sitting in my living room!!

    My Leslie is a model 205, which is a weird, obscure model. It sat on Craigslist for over a month before I showed up to buy it, probably because it’s a rotosonic model. Rotosonic means that instead of the traditional double horn on top, this model has a rotating drum with a Jensen 6×9 speaker inside of it. Since organs sort of need that screaming, bright sound that a horn gives, most keyboard players would scoff at this substitution. However the trumpet is bright and screamy enough already so the 6×9 speaker works out well for my needs.  Here’s an album of pictures I took (click the arrows to see more):

    Leslie Model 205

    The model 205 is also weird in several other ways as well. It incorporates 5 separate speakers which are independently amplified by a large tube amp and selectable with a relay box. There’s the rotating drum up top with two 6x9s inside (one on each side), another single 6×9 on the bottom inside the rotating drum which spins in the opposite direction, a stationary downward firing 15″ inside the center portion of the cabinet, and a stationary 6×9 which is mounted in one corner on the top. The top drum has a two speed motor for fast and slow rotation and the bottom drum has a fixed, fast-speed motor. The cabinet itself is also slightly unusual, with a different number of louvres than most Leslies and no split in them.

    All in all, it’s a total oddball, but one that I think I can configure nicely to fit my own preferences. When I searched for pictures of this model online I could not find any photos of it, only a single video on YouTube from a guitarist who had reconditioned one. For that reason I have posted a lot of photos here in case someone else is trying to research this obscure model.  The top drum itself is also different than the bottom drum despite the fact that they appear to hold identical 6×9 drivers.  For some reason the designers at Leslie decided the angle the top speakers downward slightly, and added that lightning shaped baffle which partially covers them.  Why?  It just is.  Roll with it.

    Getting this Leslie is a major coup for my little home recording operation, and also for the realtime enjoyment of the sounds as they’re being created. It’s gotten me thinking about the major shifts I’ve gone through in the evolution of my electric setup into what it is now. This feels like the beginning of a new era for me. Looking back, I think I could group my setup into three distinct phases:

    Version 1 (The Muse Cafe Dawning):
    Yamaha Silent Brass as pickup, softshell pedal case on the floor, amplified by a Mesa Boogie wicker-faced guitar amp

    Version 2 (The Crystal Gravy Setup):
    Audio Technica wireless mic as pickup with feedback suppressor and SWR bass amp for amplification with pedals in a hardshell case on top of a keyboard stand

    Version 3 (100% Juice Style):
    Barcus Berry brass transducer as pickup, custom wooden pedalboard on top of keyboard stand, SWR bass amp, DI input box for recording pedalboard (later a Behringer mixer), shure SM57 on straight stand for acoustic sound

    Version 3.5 (The Acropolis Refinements):
    Leslie rotating speaker, PedalGenie rental pedals adding variety, powered Mackie mixer for recording pedalboard, Sennheiser E609 Silver on boom stand for acoustic sound

    Anyhow, I’m very excited about this baby.  You can hear it on this recent recording which I uploaded to my YouTube channel.  It’s being used by the organ in that recording, which is the traditional, easily identifiable way to hear it.  Note that the keyboard is not adding its own leslie effect, so the warbling and the tremolo you hear on the organ is all due to this speaker.  Man this thing is neat!  I’ll have some trumpet recordings with it in the near future…

    A Relic of their Apogee: The Kenwood KA-8300


    2015 - 04.06

    The Kenwood KA-8300

    Probably the coolest piece of audio gear I have is this 1975 Kenwood integrated amplifer, the KA-8300. Kenwood’s not typically a brand associated with hi-fi now, but back in the day they built some real beasts. And beastly the ‘8300 is, weighing in at 35 pounds. It looks and feels like Kenwood had something to prove with this unit. Power is 80W RMS per channel into 8Ω with 0.1% THD rated from 20Hz to 40kHz. That power rating, being from ’75, is surely conservative. It can also handle 4Ω or 16Ω speakers too, which is somewhat unusual for this time period. The most obvious distinguishing features of the amp are those sweet-looking meters on the front. Watching these is a pleasurable novelty and has actually taught me a bit about the amount of wattage required for typical listening levels…not much! There is a toggle button which swaps the meter range between 3W and 100W. This switch is almost always left on 3W if you want to see the needles bump at all. That surprised me, just how little power is actually used for most listening.

    The KA-8300 has pre-amp outputs which can be used simultaneously with the speaker outputs if you want. When I bought a power amp off Craigslist those came in handy for testing it out. But maybe the most useful feature on this unit are the turnover controls, which are 3-position levers that affect the frequency of the “bass” and “treble” tone knobs. Having the option to move those frequencies around actually makes quite a difference in the usefulness of the bass/treble knobs since it allows the user to tailor the controls to match the speakers being driven. Similarly, the “Loudness” EQ adjustment (which boosts highs/lows for better listening at quiet volumes) has two settings. When listening on the Marantz HD-770s which have a 12″ woofer, setting #2 definitely sounds better whereas on their little brothers, the Marantz HD-440s, switching to setting #1 gave a better bass sound. Loudness is a nifty little circuit which I do prefer to use when the volume is at a low/normal level.

    Although this model was not Kenwood’s top-of-the-line unit, I believe it was only a rung or two below that. For the extreme collector, there is a rare copper-colored faceplace and a slightly higher wattage unit that was otherwise virtually identical in feature-set to this one. Those amps command a much higher asking price but I felt this one hit the sweet spot of equalization features and power for the dollar.

    The KA-8300 is totally built like a tank. The proof is in the pudding too, since when I bought this unit on eBay from a vintage-electronics restoration shop, the faceplate was in perfect condition. As you can imagine, I was quite disappointed to see that it arrived with a bend on the upper right corner despite the fact that the unit was very well pacakged by being wrapped up with bubble wrap and styrofoam around that. 1/4″ aluminum plate doesn’t bend easily and after attempting with a large pliers and channel locks, I gave up and decided to call it character. What I learned in the process is that it would take a lot of force to bend that faceplate, meaning the unit sustained a pretty good impact and has kept right on ticking, functionally. All the knobs and switches work good and I hope this one should be a centerpiece of my audio collection for the rest of my life. Here’s to many late nights of musical enjoyment…

    Fixin Up Some-a-Them Vintage ‘lectronics From The Texas Countryside


    2013 - 07.05

    This week I welcomed another neat vintage piece of gear to the collection, the Panasonic RA-6600. Featuring an 8-track recorder. 8-track, kids! It’s like cassette but bigger! I bought this puppy for $20 from an oddball fellow with a loud-mouthed pet bird way out in the Texas countryside. His girlfriend, who had been sunbathing in the back yard, walked through the living room in a bikini and said sorry. Dude responed “ain’t like this feller’s never been to a beach before!” I tell you I felt right at home.

    Anyway at the time I bought it he said he thought it wasn’t working due to blown fuses on the back. Well, I replaced the fuses, still no dice. I noticed that the speaker cones would move all the way out to their max position when I hooked everything up and turned her on. That means DC voltage was going out the speaker terminals, thereby a blown transistor on the power amp section. Fortunately, this receiver uses a modular power amp design, so I just got on eBay and found a replacement STK-040, which clocks in at a devastating 10 watts RMS.

    Opened it up and removed the old power amp with the help of me mate Vincente and discovered that the solder pads fall right off the 1970s PCB. Hmmm. Can’t solder anything into a circuit without solder pads. I put up a thread about it on a forum, and the helpful folks at all about circuits said hey no problem, just add some extra wires that follow the traces and connect to the next component lead. DUH! So I added the wires and bam, the right channel started working! The taste of sweet half-success!

    I was feeling happy, having replaced the modular power amp and fixed the right channel, but also feeling a little daunted by the prospect of trying to troubleshoot the left channel which was still out. If it wasn’t the power amp, it could be something much trickier to locate. Hmmm. The Panasonic, along with a whole mess of tools and other junk, cluttered up my dining room table for a few weeks. My buddy who helped me install the modular power amp came back for another visit last weekend and we had sat down to chow on some tasty salmon burger action.

    I had turned on the radio because it was there, and there was a blues station on. My buddy, a guitarist, decided he wanted to hear this better, so he turned up the volume a bit. A ferocious crackle came from the dead channel… followed by music! Apparently Vince has got the magic touch?!

    I had previously tried working the volume control around, wondering if the potentiometer might be dirty, but I didn’t get any crackles at that time. Guess I just didn’t try long enough. Or maybe that inital round of deox-it had a delayed effect? Sweeeet. While the unit was apart I gave the volume pot a good blast of deox-it, and the crackles seem to have gone away. Also replaced the burnt out bulb and the dials light up now too. So it’s seemingly 100% now! I don’t have any 8-tracks to test out the player, but maybe I might get on eBay and pick some up soon. It’d be pretty neat to make some 8-track tapes…..

    The BBCP: Bill’s Boat Cassette Project


    2011 - 08.23

    Ever been jealous of a present that you’re giving to someone else? This tape collection is totally like that.

    My buddy Bill acquired a boat some time back, and since I knew I’d be chillin on it with him over my Wiscotrip this summer, I wanted to bring along some hot jams. Deadly hot jams. As detailed previously, being able to provide the proper musical playback format involved getting a cheap tape deck and makin tapes. And here’s the results:

    The tapes:

    “70’s Cactus Vinyl Funk” Mixtape / “So Funky It Hurts!” Mixtape
    “BOATCHASE!” Mixtape / “Modern Funksters” Mixtape (not shown–it’s in the player!)
    “70’s Vocal-Funk” Mixtape / Donny Hathaway: Live
    Orgone: Cali Fever / Orgone: Killion Vaults
    Greyboy / New Mastersounds
    Carlos Santana & Buddy Miles: Live (Sides A & B)
    Curtis Mayfield: Superfly (Sides A & B)
    “Heady Downtempo” Mixtape / Scientist Dubtape
    Easy Star Allstars: Sgt. Pepper’s Lonely Hearts Dub Band (Sides A & B)

    Click on the linked titles to Listen!

    Some of it is taped directly from vinyl, others are recorded from the PC, where I’ve got a nice retro-wamrth compressor/limiter program that brings out the detail on those tracks. As you can see, there’s a definite genre theme here with a heavy amount of funk. That’s what Bill digs the most, and also I wanted to stay centered there so the whole collection would have its own ‘vibe’, as the soundtrack to the boat. The two exceptions to the funk theme would be the Heady Downtempo/Scientist Dub mixtape, which I envisioned as something you’d want to put on while floatin on the lake after the sun’s gone down, and the Easy Star, which is just such a killer record I had to throw it in.

    There’s a veritable cornucopia of killer jams here, a substantial portion of which will eventually get posted on the site. Stay tuned for the full lowdown.  In the meantime, check out the SS Advanced Manoeuvres
