Hi Eric
When working on this old stuff, I've found that they tend
to use the same transistor in many different locations and under
different operating conditions. I've aften found that I can
swap transitors around and keep original parts. I just attach
a lable to let myself know what I've done in case it dies completely.
Also, one thing to look out for, other than leakage with
the germamium transistors is an increase in the DC resistance of
the emitter base connection. This usually shows on the emitter
side so it acts like a emitter resistor in circuit.
It shows clearly on a curve tracer.
