Nice amp. I see this amp suffers from the same factory oversight/mistake as other late 1968 'transitional' amps of this style. The mistake centers around the two 10K/1watt B+ dropping resistors for the preamp. The way it's wired up currently has the B+ voltage not going through the last 10K/1watt resistor before heading over to the two 100K half-watt plate resistors for V1.
It looks like it may be bypassing the choke as well - presuming the two red wires are the input and output to the choke?
