"If you are looking at this then you probably know something about the Rhodes Chroma.
It's a Beast of a synth! And this one if fully operational and updated. And, shipping is free in the U.S.
The major upgrade is the Chroma CPU Plus (CC+).
This updated CPU gives you all sorts of features, most notably MIDI. But also general stability. Read about it.
The other necessary upgrade is the new power supply. The original power always eventually goes out on the Chroma. Hand made in Italy this new power supply brings stability to the entire system.
You can find info on these upgrades on the RhodesChroma website.

Every inch of this synth has been gone through by my synth tech. Here's a note from him about all the things he took care of. If you have any more specific questions about what's going on with the Chroma we would be happy to talk with you.
--------
The Voice boards have had all of the electrolytic capacitors replaced, and the 4000 series cmos multiplexers and decoders have also been replaced. in 6 of 8 voice cards the RC4151 chips were replaced. many but not all of the chips had chip sockets installed to make for easier repair in the future. (some of the chips had been replaced already before I got there, and in some cases I just ran out of IC sockets) but for the most part it should be far less of a pain in the ass to replace the ICs on the voice boards going forward.
The mother board has had the electrolytic capacitors replaced and also had a number of the 4000 series cmos chips replaced. (CD4016, CD4566… etc..) in addition the LM311 comparator was replaced and the dual audio opamps were upgraded.
On the IO board many of the buffer, decoder/encoder, and flip flop chips have been replaced as well as electrolytic capacitors."
