    TransTube was never trying to communicate it had tubes. Rather, it was Peavey's circuit design that built tube-like behavior from transistors ("TransTube"). It's surprisingly effective.

      Well, I loved the reverb :) The distortion sounded very typical solid state to my ear
      It made me think off George Carlin, saying "no tubes" hehe

      I sold mine. I miss the reverb on it. It was better than on my Mesa Boogie Rectoverb :)

    my used amp is very quiet when plugged into the high and low gain inputs, I can't find any fix and I don't know what to do

      Im sorry, Im not sure if this is a question, or a comment?
      If you have a question about fixing it, please describe the problem.
      Thanks and best :)

    Mike, what was eventually the reason for the overheating? It is not resolved in part 3 :-(

      Hello!
      Im not 100% sure, but I believe it had something to do with using my relatively high signal generator as an input, as a guitar probably has at most 1/1000th of the power that usually goes to the input of an amp, that being said, a guitar pedal should boost that up to a similar level as my signal generator (50mV).
      I think that the above, compounded with a a load that had very little inductance, may have exacerbated this effect.
      Again, I am somewhat speculating, I haven't had this issue before, but it seems like the most likely cause.

      @@mike-PlatinumAudio Thanks for the quick reply! so I will go for the usual suspects on my board (bad power transistors, faulty opams, bad solder joints ...). I've got a Silverstripe Bandit I want to revive; blown fuse for unknown reason and a faint hiss plus heat after I inserted a new fuse and powered on ... let's see ...

    That is not a StudioPro112.

      Thats odd, what do you suggest it is?

      @@mike-PlatinumAudio Thanks for the link. My SP112 is a Red Stripe and that's what I have all over my face right now. It's innards have one power amp chip with 11 (!) leads on it that I had to replace once. That's why I was confused. Quick story -It smoked one day and blew the fuse. I opened it up, replaced the fuse and watched where the smoke came from. I sent a picture to the Peavey service and parts desk ("Hiya, Hon. What can I do for y'all"). They got back to me almost instantly. "It's the power amp chip but it's going to cost $7.00 to ship." I says, "OK, how much is the part?" "Oh! You want one? It $14. Plus shipping."
      I figured it was worth the money just to see if I could fix it myself and sure enough after some research it works perfect.
