[sdiy] Possibly OT Tube Amplifier Question

[Scott Gravenhorst]

Does it count as "on topic" if I want to use the amp
with a synth?  <grin>.

Anyway, it's an Ampeg J12R Reverbojet.  It's output stage
is bad (uh, sockets are partially melted).  I've thought 
about rebuilding it using matched 6L6 tubes (I have them), 
but I've been told that it may require resistor changes.  
I have the schematic, but I honestly don't know enough 
about tubes to re-engineer the circuit.  The original 
output tubes are 7591.  Both the 7591 and 6L6 are tetrode 
power types, the 6L6 being a little less powerful.  I chose 
6L6 because I couldn't (at that time) find any type 7591.  
Perhaps I don't know where to look for replacement tubes.  
I wouldn't mind just putting it back to normal.
