OK, false alarm. The Sondek LP12 at my local dealer was too good to be true. Not sure of the DOM, but it is a Valhalla/Ittock model, with a 70% worn Dynavector XX-2A. The upgrades were that the local dealer rebuilt the Valhalla power supply & installed the trampoline, so no Karousel bearing, Lingo PS nor Kore arm board.
The only good news is Audio Advice was a Linn dealer and the technician is well trained and experienced & the price is now $2,200. It probably is a reasonable price, but no steal. I think it is a pass.
Thank you for all your well informed advice! It’s been fun learning about the LP12.
