  • Early version Gibson GA-30RVT

    Looking for the schematic for the 1st version of the Gibson GA-30RVT.
    This had simple controls vs the later versions
    Each channel had just a Volume and Tone control
    One had the Reverb control
    There were two controls for the shared tremolo.

    It looks like it was made in 1962/63.
    It appears to have a different tube line-up than the later version as well, only 5 preamp/pi tubes.

    I've been told it may be the equivalent of the Epiphone EA-12RVT

      The version I'm looking for had just Volume and Tone for each channel
      The pictures have a group of five controls and then the two shared tremolo controls.

      I found a schematic for what appears to be the Epiphone version but it was a 4 x 10" combo, not the 10" & 12" of the Gibson combo

        So that's the only difference- speaker configuration? I wouldn't think that would be a problem if the schematic is otherwise the same?

          The speakers don't matter, they stuck the same chassis in different combo cabs. And welcome to the world of Gibson/Epi, I have one model that I have SIX different schematics for. They changed them all the time.

          Here is the Epi you mentioned, does it match your amp?
