1975 Rhodes suitcase pre amp

Postby rhodestreet on Fri Mar 18, 2011 8:04 pm

Hi,I have a rhodes 1975 suitcase piano.I only have sound coming out of the right side of the cabinet.After doing some tests i found all speakers to be working,both power amps to be working and have traced the fault to the pre amp.I'm looking at rebuilding the pre amp with the kit provided on vintagevibe.Firstly i would just need to know a few things.
The main thing i need to know is the polarity of the capacitors in the pre amp?
Also which transistors are NPN and PNP?
Is what im asking covered in the video(4 pin suitcase amp repair video)
Thanks and hope to hear back soon!

Hi.
Did you find the problem ?
My 5 pin amp plays on the right speaker when I switch the vibrato on and turn up the intensity pot to 10.
