  5. Commodore 64 replied to the thread 5E3 witThe a beefed up OP teansformer.

    1750PA sounds great with EL84 or 6V6 in my experience. Also dig the 1760H (6.6k), can't go wrong with either. Going to 8.4k from 6.6k,...

  9. Commodore 64 replied to the thread Anyone ever use common cathode coupling as phase inversion with 6L6 power tubes?.

    I believe there's a bit more power than parallel SE. I think the tone is a little sweeter, too. The SSBH below (last page on the...

  10. Commodore 64 replied to the thread Look at my guts - what is all this stuff ?.

    Looks like a germanium diode to me. Some kind of voltage limiting circuit? Did some googling....

  11. Commodore 64 attached a file to the thread Anyone ever use common cathode coupling as phase inversion with 6L6 power tubes?.

    Yes, I have. I've built a couple self-split amps. Really dig the tone. It's much less efficient, of course. But it does work, and it...

    No, look again. That's mV, not V on pins 3 and 8. V5 pin1 456vdc , pin2 -40.1vdc , pin3 000.1mvdc , pin4/5 3.285vac , pin6 414vdc ,...

  15. Commodore 64 replied to the thread Updates on 81 Pro Reverb problems.

    Those high V5 plate voltages seem like there's no current being drawn (it's approaching the node voltage, right?). Also there's nothing...
