Your dealer sounds a little confused (actually a lot confused, maybe he wants to sell you something new?). I would call Harman Specialty Group directly. I just received a new transport screw strap mechanism a few months ago. Jamie Cohen is head of service there and is one of the most helpful,informative
audio-engineers you could ever hope to meet and would never give you an answer like that. I'm sure if you start by contacting Richard below you'll get your problem solved.

I would call directly and ask for Richard or anyone else in Mark Levinson service. HSG has a group of audiophiles/engineers devoted to providing service for Levinson electronics, revamping the current line, and develping new products that maintain and enhance the Levinson name.
I know there were some concerns during the transition of the company as things were sorted out, but I would not hesitate to buy Mark Levinson equipment today either new or aftermarket on Audiogon.
Hope this helps,
