Rock-ola 478 - how to test power supply
I bought a 478 a month ago that works great, but the Hit Tracker is dead. Each of the song-tracking 4 displays have a burn-out point on the board, leading me to believe - the root cause is the power supply.
I have the service manual but it does seem to have voltage test- points. Is there a document that has them, so can test the PS, before getting and plugging in a replacement Hit Tracker?
Thanks! Dale
