Just to confirm.
The foil on the back of TDA2030 was still intact. I contacted Zoom and I was given an apology and £15 off my next zoom purchase. Several of The amps made around the same time as mine had similar faults. Xbox 360s get it all the time.

Will update when tda2030 arrive.

Wow, that's really strange.  At least they are owning up to it and giving you a bit of credit on a future purchase.

Tda2030a fitted.
Buzzing remains.
Any thoughts, dry pots are my next idea.

As is often the case the issue probably damaged more than just the chip.


Tell em to keep the $15 and send a new whole new rig :trouble

Given the situation, I agree.  However, it should still be repairable it will just take more work.

Next rather obvious reason for severe hum would be faulty filter caps or regulator circuits.

Okay, so at this point I'm thinking maybe I'll pay a specialist to fix this, the tda was fun and simple but anything above pots and I'm not the most eager to be poking around.

Capacitors are an easy replacement and really the rest of the circuit shouldn't be much more difficult than what you did replacing the tda.  Unless of course it had something to do with the modeling circuitry - which is unlikely.

You likely won't see any more damage, but you would rather have to start testing for it with a voltmeter etc.
