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.
