Hi all
I have a Sony sw-77 and it appears to be acting up.
It seems to have a problem in the power dept, now I'm not sure if it's
because of the batteries, as I have cheap things in it at the moment, but
its still the same with the ac power supply fitted, it sort of crackles and
goes quiet for a few seconds, then sometimes it sounds as if it drifts off
frequency, but then it comes back again, it is an intermittant problem, but
very annoying, any ideas anyone please

I've had problems with the coaxial(barrel connector) power jack on
various equipment. The connections to the circuit board go open because
it gets stressed a lot with the plug and cord getting moved or bumped
and the only thing holding it in place is solder. And in some stuff,
there's a switch to disconnect the battery built into the power jack so
that supply goes through that same problematic part.

Wiggle it and see...
