The fact that you can still find a DP80 (or a DP75) for less than $1000, albeit in an unknown state of repair, is why I don't sell my mint DP80 that has been completely re-capped and re-transistored and had its control chip replaced; no one would pay a fair price in relation to its performance. I would hold out for either of those two over a DP60, especially if the DP60 has a demonstrable problem such as the one you describe. The DP80 is one step away from Denon's all-out effort, which was intended for professional use, the DP100.
Vintage Denon turntable
I have an opportunity to purchase a Denon DP 60-L turntable for three hundred bucks. No cartridge. It is in beautiful cosmetic condition and will appear to power on, but does not turn the platter. Questions: If this TT can be fixed, is it something I should want to own? How much would it make sense to put into having it repaired? Where would I send it to have the work done well?
