I've got one... somewhere! It might take five minutes to find it or it might take five years! I sold mine in 1990 and the last time I used the schematic was to repair it before sale.
The circuit itself is very simple to work out though. There's the audio filter, three almost identical sections for each channel and the power parts. What's the actual problem with it? |

if the power neon comes on and there's no load on the unit, it will appear the unit the unit is dead the channel neon will not light with no load on each channel
this unit will only run non inductive loads
the power supply is very simple its a 6k8 7w resister , 1n4007 , 6v2 zenner hung on the mains neutral
