spectron musician III mark 2 repair

Have a musician 3 mark 2 with one channel out. I understand the manufacturing facility in California has closed. Anyone have any recommendations on where to get this repaired?
I had my Digital One rebalanced at my local repair shop in Chicago, Deltronics. 
I've got the same amp with the same problem.  Any suggestions?

I just sent an email to Deltronics. Let's see what they say.

They said they would work on it. Deltronics in Chicago.
