no tipsy amp repairs please, it will end in tears.

1. ascertain if its an output module or something else.

(swap entire module from one side to the other)

2. either repair the 'something else' (pre amp) or

3. ascertain whether the faulty module is the switching or amp pcb

(swap boards with well-marked good side)

4. Go over the faulty board part by part. On a simple amp like this its quicker to cold check components rather than get in an endless loop with signals and offsets and long tailed pairs and whathaveyou.

Thanks Kev, definitely no tipsy amp repairs. The weather is so glorious I’m going to be bbq’ing in the garden and not hunched over that infernal amplifier.

Your methodology makes sense, this was the better of two blown modules and so I had hoped that it would be more likely to work.

I’ll go through the other one, swap halves back and forth and see if I can get any further. Thumbs Up

No update as yet I'm afraid.

I got mixed up in a Yamaha M85 and the active crossover in the car has just died and so it's gone on the back burner for now.

I'm going to rebuild the other module so I can do some swapping around, hopefully in the week.
