The saga is complete... for now. Got the new transformer from Triode and wired it back in the other day - still working like a charm and no more hummm. It's great to have a working phono section again so I can listen to yummy vinyl.The SCA has a Tape Out channel so next I'm going to send that thru a pre-amp to my ST-35 and power some remote speakers. And so begins my quest for a fuse holder

I think I'm in love. Currently hand-made and available only from moname.org, this USB powered control surface is a completely programmable device meant to be used with music control programs such as Max/MSP, Pd, and other MIDI, OSC etc music control languages. The website features free application software to run the device, as well, which does not require the purchase of Max/MSP, so there are

I installed the new power transformer in the SCA-35 and got everything wired back up and at first was really psyched to listen to some vinyl again. After a couple of records, though, it became apparent that the new transformer was humming loudly, without too much detectable vibration. There was also a slightly softer hum through the speakers which sounded like maybe a little ground hum. But

So I hauled out my Dynaco SCA-35 the other day. I had raided it for parts awhile back: stole the power transformer for my ST-35, and a couple of big resistors from the rectifier / filter circuit. Been gathering dust ever since.I finally found a replacement transformer from Triode Electronics and now I'm putting it back together and am thankful I found these:http://www.dynaco-doctor.com/SCA35%

This isn't really about tubes but it is definitely part of my quest for good sound on the cheap.I went on my first real adventure in car audio when I installed a pair of vintage 12" tri-axial EV speakers into my '66 Barracuda last summer, but that's a story for another time...Back to our hero:My wife and I just purchased 2 used Saab 900's, and I have been busily pimping both rides on my lunch

The more I closely I listen to sounds and music, the more I notice environmental noise. My house, especially, is very noisy. The fridge hums, the furnace rumbles, the TV hums, the electric heaters hum, the dishwasher sounds like two cats in a dryer, and most of all, the computers hum and bubble as drives are accessed repeatedly for no apparent reason, as update after update loads

I got this e-mail today:You contacted me about obtaining oil for the Tel-Ray memory cans. It is called Ucon LB-65. My contact is Jim Rutledge. He can sell enough for two machines. It only takes about two tablespoons. He wants about $25 payable by check. Contact him for details: rutledge@fayelectric.com I hope this works out for you!Slightly ironic as I just sold my Tel-Ray on eBay.

I am intrigued. Apparently a plasma speaker has no moving parts and uses a plasma flame to project high freqauency sound. The device uses tesla coils, and apparently this also causes the room to fill with the smell of ozone. How cool is THAT? http://www.plasmatweeter.de/eng_plasma.htm http://www.ece.villanova.edu/~cdanjo/plasma.html http://homepages.ihug.co.nz/~andrewp/plasma_speaker.html

I've set up the HD24 ADAT with an 8-channel pre-amp and misc mics. I've been making some nice recordings of the band during rehearsals. Still need to experiment with mic placement and doing the recordings more deliberately (e.g. not all play at once). Now that I have a no-brainer, non-fiddly, non-computer tracking setup, I'm setting up a PC-based editing system; I'll probably use Cubase as the

I'm contemplating a computer setup for my home studio. The "Academic" version of Cubase SX is available here for $349.00. You have to go through some process where you prove you are academic - hopefully working for Harvard University will do the trick... From what I've read, the Presonus FireStation seems like the way to go to interface to my laptop. They've just lowered the price to $499

A Dynakit PAS-2 Preamp and a Dynatuner, both stock. I got them both for a very reasonable price, esp. considering both units work perfectly. The tuner was advertised as an FM-1 tuner, but since the FM-1 is a mono tuner and the one I have is stereo I think it's really an FM-3. Update: Okay, so now I'm pretty sure this IS an FM-1, but with the optional FMX-3 stereo adapter, available

From: http://www.audioreview.com/Amplifiers/Dynaco,Stereo,35/PRD_115773_1583crx.aspx If you do have or get one of these amps, you might want to try the following: change out the cheapy bluish-green coupling caps to some better caps. If I was doing this today, I would look into the inexpensive Chinese paper-in-oil caps that Steve sells at Angela Instruments (www.angela.com) as my first choice.

Some ST-35 upgrade suggestions found on http://www.audioasylum.com/forums/dynaco/bbs.html: 1. Remove C1 and replace with plain wire jumper (modern preamps have DC blocking caps in their outputs.) 2. Replace C4 and C5 with a high quality .1mfd 400v. coupling capacitor. The caps in the amp are old, cheap Radio Shack Parts. Recommend (econmical) Sprague orange drop or Dayton film and foil cap or (

Cool! It worked! I doubled one of the .047 uf caps and the tremolo slowed down - a lot. At first I did the cap that is closest to the Depth pot and sure enough, this seemed to increase the depth. Now that I moved it to the first cap the depth seems "shallower". I might go to a .033 instead because it's almost too slow, now. Also, the signal sort of gets "lost" at the fastest speed. Maybe I

I tried the 500K audio pot and (as I suspected it would) it changed the variation of speed to a logarithmic sweep, but the slowest is till the same speed and the fastest is still the same speed. I want to make it slower on the lowest setting. If this makes the highest setting slower, too, that's okay. I found some info on the web: Slowing down the tremolo ...that describes a tremolo circuit

Well, I got the GA 18T sounding a lot nicer, now. I bought a pair of used 6BM8's from Audio Pro and plugged them in and the amp was like a new beast. It was still a bit gravelly so I swapped thru a few 12AX7's until i found one that sounds nice and clean. There was some buzz/hum at first but playing the amp more seems to have reduced that effect. Now I want to get the tremolo to oscillate

I'm deciding whether to buy a Gibsonette GA 8T guitar amp from a friend. It's not a GA 5T but it does have tremolo so I'm checking it out. Right now it sounds gravelly at any volume and the tremolo does not work. I have it on loan for a couple of days to try to figure out what's wrong with it and then I can decide if I want to buy it. It uses a 12AX7 pre, a 5Y3GT rectifier, and 2 6BM8 power
