A friends dr who Pinball wpc sound board is blowing both 3a fuses on power up.
C26 cap had blown apart and a trace on the back had destroyed itself. Re newed the 1uf tant cap and the trace. Also volt reg u3 and u4 replaced because I had some. The big 4700uf caps don’t look domed but I’ve ordered some.
Any sound board experts that could point me to the real culprit?
Many thanks
