Hi my Star Castle Audio board works fine and sometimes not. What happens is the q17 and q18 get piping-hot and eventually blows the breaker #1. I have two boards and they both do the same thing. I have replaced all electrolytic capacitors on both boards and transistors q17, q18 ,power transistors ic4, ic5. I was thinking the next step would you go for the op amp.
This seems to be an intermittent problem as sometimes the machine works perfectly with no heat and other times it heats up and shuts down right away. Makes it more fun for troubleshooting.
Any way any help would be appreciated
