Why not try Analogique in NYC (Analogique Systems Laboratories, 17 W 17, 212-989-4240). I have called them in the past when I was considering buying some used transports and they always said they could fix them, though I never had to use them. They have a superb reputation and specialize in turntables, which are similar to spinning cd transports. Not cheap though, but have to be cheaper than the outrageous Harman price.
Transport replacement costs - Proceed
I finally got to a point where I called Harman for a RMA number. My Proceed PDT3 (I think) may need to have its transport replaced. Last year I was unwilling to send it in because (at the time) Harman was charging a flat $1000 "entry fee" for servicing this older line of equipment. They now have a "not to exceed" fee (which covers both parts and labor). In the case of the PDT3 the NTE fee is $995. I am a little unwilling to be socked with an almost $1000 fee for such an old (but still awesome) transport. When I asked the guy what he thought a transport replacement would cost, he was unsure. Does anyone have any recent experience in helping me understand whether this kind of work would be bumping up on to the higher end of that NTE fee?
