So... are you ready to swap trannys?

(I'm a bit confused. Does this unit actually use driver transformers? It's
hardly a recent model, but I thought driver transformers had disappeared a
few years before this series.)



I think he meant trany istor.

Used to have bad transistors in some Tek scopes that ran hot.
over time the internal connection would become unstable and poking
would bring it back. Probably just the solder joint.

That'd be my diagnosis too. Happens all the time with heatsinked parts,
because the pins don't get hot enough to 'wet' properly when they go
through the wave-soldering machine at the factory.
