I hope you guys can help me.
I am restoring a Mark IIB that has had some significant modifications and was in a very bad way when I purchased it. I am restoring it to its original condition. I am carefully going through the circuit against what I see on populated on the PCB and I am finding a few anomalies. The main one is a 1 meg resistor located between V1B and V2A and I have had no luck locating it against the circuit.
Below is a photo that shows the 1 Meg resistor on the right hand side near /under the capacitor.
I have indicated on the circuit below where I believe the resistor would be located on the circuit.
Can anyone tell me if this is original of if it has been added later or if I should remove it or leave it. I'm just about the fire up the amp for the first time and I don't want any problems!
Thanks for your help
