Rhodes Chroma Arp Analog Synthesizer

via this auction

"I bought this synth around 1997 in working condition with the Syntech midi interface.It worked for a year or so and then suddenly during a session it stopped functioning.I had lots of synthesizers so I just took it out of the lineup and put it in the corner of my studio where it stood until week ago.I didn't get online until around 1999 so I researched the problem I might have encountered.It seems the power supply was this synth's main Achilles heel.I've watched a couple of youtube videos and the power supply wasn't producing enough power on each rail to support everything functioning.My machine turns on and there is a rapid fire clicking like an old computer printer.I learned this is the tapper solenoid (which is used to add tactile feedback to the membrane switches)."
