Got one of these I'm resurrecting, built by Jess Oliver, the man who designed the Ampegs B15's etc.
Found schems here and online, it uses 6L6 output tubes, and 6EU7 preamp tubes and a 6AN8 for the phase splitter.
Trem works, reverb return works, but no reverb send.
Does anyone know if the reverb send is supposed to be a 6DR7?
One place I read it uses a 6EU7, another a 6DR7
Heater wiring is wrong for a 6EU7, but right for a 6DR7, very similiar. It had a 12AX7 in this slot, which may work if I could wire the filaments correctly, and provide a cathode circuit for pin 3, 2& 3 are tied together on a 6DR7, which makes me think that's what's supposed to be in there.
Just wondering if any of you know for sure if you've worked on one.
Thanks.
