Glad to see you got the amp working!
You mixed up the 100K OD entrance trimmer and the 10K PI balance? Or you adjusted them incorrectly?
You may want to measure and post all of your voltages too.

They were the wrong way round, Yes I will. Also noticed I have biased it super cold at 16mV(mA) at the 1ohm Resistors... Way too low. I misinterprated my friend when he said 16 he meant Watts.

I suggest you use this very handy calculator to help you bias your amp.

I’ve checked I’ve never ordered at 12b. But what you are saying is very interesting and I’m keen to explore this further.
I have attached the 124 Layout that’s on here and the AA electronics layout for the 102 and take the outputs out of the chassis for closer photos.
Looks like the jacks are correct in the AA layout but they are labelled incorrectly (swapped).
Are you referring to the SPK1/SPK2 mislabelling? As in SPK2 is the MAIN SPK?

Yeah no biggy, got it all sorted anyways. I will be rebuilding this at some point to look better aesthetically.
Fabulous amp and sounds better than my 50w version
