Hello there, I wonder if anyone can help with the service manual for this model ?
I already have the SPA22 (a 40 page document) but I need the HD version which has slightly different boards
Thank in advance , Mike🙂

I've got round it without a service manual
A whole shed load of smd caps were replaced initially, and I'd missed about 40 33uf/16v caps on the bottom side of the analogue audio input board (all effectively fried)
They were badly fatigued enough to trip up the +ve 9v produced on that board , the 7809 regulator tripped over and went to ~0.8v output.
BUT only if it was already connected on boot up, if you connected the 12v feed to this board after it booted it would stay up at the correct +9v output!
