United States

CAE Sound (San Mateo, California)

My old boss, Peter Miller is still fixing them himself and his Chroma Service diploma is still hanging on the wall." [June 1999] Chris Ryan [21030691] had his Chroma serviced at CAE Sound in October 1999, and they did a wonderful job refinishing the wood, which had been damaged by the common problem of deteriorating foam in the case.

Recommended by Uro [21030401], who writes, "Take it to Greg M: you may have the fortune that mine will be there for comparison, entrails also on display. Greg fell in love with my Chroma after I took it to him the first time—and this is for a big guy who breathes Sequential IC's!" [November 2005]

We were (and are) a Fender Repair Station dating from the time of the original distribution of the Chromas. We have schematics and can still repair Chromas within reason.

Mike Metz, Thesis Audio Service (Wichita, Kansas)

Edward Chen [21030674] writes, "My Chroma started showing all the symptoms of a bad PSU and he was able to troubleshoot and correct it without me having to ship the whole unit to him. Had it back within 2 weeks time and it's been running like new ever since." [October 2006]

Kevin Siegenthaler [21030603]

Stephan Vladimir Bugaj [21030860] writes, "He is the only one in the Bay Area other than CAE in San Mateo who would take [my Chroma]. He seems knowledgable about the system, is himself a Chroma owner, and has mentioned other Chromas he has repaired. But he's a generalist. He is independent and his shop is a residential garage." [September 2012]


United Kingdom

Roy Paynter

Paul Hackett-Evans [21010094] writes, "Roy Paynter is one of the original Chroma trained engineers, and he has a Chroma which he uses as a testbed for repair units, swapping voiceboards and components, etc. to test and calibrate them. He can take individual sections of a Chroma and service them for you if you need. (Like the power supply from my Chroma, much cheaper than shipping the whole instrument to him.) Roy has sets of leads to connect parts of his testbed Chroma to corresponding parts of repair Chromas to make this easier and more accurate. He does an excellent job. Roy works as a keyboard engineer for a major UK distributor of high-tech musical equipment for 3 days a week, during which time he stays away from home. The rest of the week he works from his own well-equipped workshop near Peterborough, England, where he services Chromas and all manner of other instruments. He only uses his email, <>, to contact component suppliers and keep in touch with his private clients." [February 2001]

Virtual Music

See Rhodes Chroma Zone. Alexander Guelfenburg writes, "Virtual Music has more than 25 years of experience in repairing synthesizers like Rhodes Chroma, PPG, Fairlight, etc. I have a Rhodes Chroms testing system and owners with a fauly voice card can send us the broken voice cards to be repaired - no need to ship the whole Chroma. Virtual Music offers worldwide service, we care about shipment, customs papers and - of course - the repair service. Quite convenient also for international people." [February 2015]

I got the new power supplies from Service Connection ... they installed the supply in my Chromas and also a fan." [April 2001]
