Regarding Deltronics...
I recently took my Yamaha CA-2010 there for repairs. When I picked it up they had damaged the beautiful cabinet. I think they dropped it while they had it apart. When I pointed this out they denied doing it. I took it home and the electronic "fix" unfixed itself hours later so I had to bring it back to them. This is where is gets ridiculous... I picked it up and it had been damaged AGAIN! A big chunk of veneer had been chipped out of the side. I couldn't believe it. And in order to right this wrong, they had (without my permission) put some wood putty in the places where they had smashed or chipped the veneer. It looked laughably bad so I asked for some money to have proper repairs made, but I've gotten nothing but frustration. He told me "sometimes these things happen". Steer clear of these guys.
I'm so pissed...
