Purchasing barely used NAD gear


I have the option to purchase some used NAD gear.   $575 Lightly used and hasn't been used in 25 years.  What kind of issues might I expect to encounter with gear this age.  It looks brand new.   I'm not as tech savvy as some of you fine folks! Stereo Preamplifier 1155, Stereo Power Amplifier 2200 Power Envelope, Stereo Tuner 4130

nad is notoriously unreliable, although the 80s stuff you list is much less finicky than their later gear and also sounds good. the amp and preamp seem to go for $200-$220 each on ebay and the tuner for $50-60; depending on condition and whether you save on shipping $575 for the set seems like a fair (but not great) deal.

remember some parts age with time,not usage...in fact some believe usage helps these parts to last longer...

@jl35 that seems to be the consensus from what I've been reading.  I would be using the amp to drive some DQ 10's. I know the amp has the dynamic power. I'd be worried the amp would probably go toasted since the 10's are not an easy load for many amps.  25 years is a long rest LoL
