DIYbanter - Germanium XSTR cross reference

Jeff,

My RCA info does not go that far back, but you should be able to take
a guess at the specs. For voltage, look at the voltage rating of the
supply caps, as the voltage should not go higher than that; I like to
exceed it by 50% if possible. For power, is it a small transistor with
no heatsink? If so than a watt will certainly do, possibly quite a bit
less. Beta? not much. Current? not likely to be very high on an
un-heat sunk device. A few hundred milliamps will do.

If you have access to a transistor curve tracer, then you can figure
out the voltage and beta by checking the transistor in the other
channel. F(T) (frequency) of the transistor is not likely to be an
issue either.

I hope this helps you out.
Regards,

Definitely germanium type. PNP

Not listed in NTE or ECG.

Anyone have a reference for a replacement.

Schematic of this model?
