Emax

Hi, I live in Chula Vista Ca.  area and I have taken to repair a Roland JD-800 and my ENSONIQ ESQ-1 to a repair shop that some friends recommended me in L.A., I saw there a lot of Vintage keyboards such as Emax's, Akai's, Moog's, Roland's that they were working on them.

My two synthezisers are working good since that, the ENSONIQ just needed a new internal battery and son keys adjustment and the JD-800 was a full recover!!, It works 100% now and looks so great, tey changed all keys, sliders, buttons, display...

By the way, I don't obtain any gain with recommending them.
I hope this will help.

Asunto: [emax] Re: Emax Rack - no sound..or barely any

  
Ok, thanks. Know of anyone in the Los Angeles area who has done work on these? How much should I expect to pay for repair? 

I'm wondering if it would be better to just sell it and let somebody else deal with the problem...
