    6l6 mystery amp

    Just bought what appears to be a homemade 6l6 stereo amplifier. It uses 2 12ax7’s, 1 6sn7, and two 6l6gc’s on each side. Has selenium rectified preamp heaters, a big choke and a ton of capacitance. Has a bunch of controls that I haven’t been able to identify yet. It was supposedly made by a...

    Potted Ouput Transformer- Is it PP or SE UL ??

    If I had an unknown overseas (to the west of CA) POTTED output transformer in my hands with 3 primary leads and a 0-4-8 secondary, how would I know for certain if it was push pull or single ended with a UL tap? This particular transformer is claimed to be UL single ended. I attached a file...

    AI to the rescue

    Hi guys, For fun I asked the ChatGPT AI a vacuum tube question: how to determine what impedance an output transformer should have to run a push pull of 6L6G vacuum tube with a 8 ohm load? The response was: If the load impedance of the output stage of your amplifier is 8 ohms, then you will...

    EL34 Tube Amp Wiring Dummy Check Please! :)

    One of the major annoyances on my very first build ever, was figuring out all the tips and tricks after already mostly assembling the amp. Drilling more holes at this point would be difficult, and before continplating starting a 2nd build, I would like to get some of these tips/tricks drilled...

    Vintage Magnavox - REDUX - Help?

    Hey Everyone, I have a 1950's Magnavox 477P (I think) entertainment console - TV, radio, turntable. My mom told me it died before JFK due to a lightning strike near her parents' house. I pulled the chassis out and cleaned it up a bit.. There are a lot of different tubes. The only ones...

    Heathkit A-6A Tubes

    Can someone help me? I have a Heathkit A-6A (trying to get working). I have a schematic but It doesn't indicate WHAT the back center position tube is supposed to be. (The front center position is a 6 SN7). Would the back be another 6 SN7? Somebody threw a 5Y3 tube in that position but it keeps...

    EL34 vs. 6L6GC vs. 7591 ? Truth - Who's Best !

    I have been doing a lot of research lately on These 3 Output tubes and other than their heater currents and the typical applications there is not any real way of comparison other than amp designs and peoples opinions. I know that all 3 tubes have their own sounds, 6L6 bright, 7591 detailed, EL...

    Looking for DIY Tube amp design

    New to the forum, I'm looking to build an amp in the 25-40W range, and I was wondering if anyone had suggestions for a good push-pull design using EL34s or 6L6s. I'm open to other tubes as well, but I'd like to stick with common and inexpensive tubes (preferably not KT88s). Given that I'm...

    Heathkit PS-4 exhibits snarky behavior

    I picked up a Heathkit PS-4 (same circuit as IP-32) regulated power supply recently to serve as a secondary supply for the @kward Special I'm also putting together. It featured nearly-all original components (including Daystrom-branded GE 6L6GCs) and sort-of-worked; Voltage won't zero-out...
