My usual recipy.
Update Caps to Elna Silmic II, Nichicon, change all resistors to non-inductive, double PSU capacity
, updated rectifiers, new RCA's + screw speaker connectors, cables PTFE copper/silver , resolder tracks/components with 2% Ag solder, new power socket.
After this update the clip indicator nearly NEVER light up when pushed the max.....;-)
