muppett:
Sorry about jumping in here but have same issue (without the melody) and was wondering how do i test the sub1 board and the 20n60c3 have compared the 20n60c3 with a new one and a multimeter but will that find a fault as sometimes if left long enough it will turn on. also noticed that cap 5065 on buffer was blown so have changed that.
