I have one laying somewhere. I repaired a lot of them. Watch out for the pcb, the traces come up really easy. Also there is a built in non switchable loudness circuit. And the power transistors love to die. Also the drivers. The connectors are not the best, so use contact cleaners.
nice touch on the removable decoder and amplifier cards
Pihe at elektrotanya surely has a service manual for it. Make sure you donate a few $ if you find the website useful.
with it being this old this thing is even still repairable

How does one learn to repair electronic devices?
