Title: Rock ola 474 amp
Post by: DaveN on August 10, 2020, 03:58:49 pm

I just pick up two Rockola 474's and the one I'm working on has static in the right speaker all the time sometimes you can hear it over the music. I have replaced most all of the electrolytic capacitors on the driver board, the pre amp and the power board with no change in the noise. has any one ever had this before.

Thank you for your help

check your connections too.  I had an occasional static issue that ended up being the speaker terminal lugs were not screwed down securely.
