I'd probably keep and convert a few of them (probably the 700s) sell the rest as "cores" for WOPL conversions. Some of us here bi and tri amp our speakers so 2-3 amps is good.
Dual 500s can be WOPL'd but you have to do the back planes/output transistor wiring yourself.
Yeah I got a couple I wanna sell but I'm gonna let em go cheap (probably on FB) cuz they got problems. That's the problem with selling them local is getting decent money for 'em/right buyer.
Maybe trade the skoolie conversion for a stretched Peterbilt tractor and pop a decent sized camper right on the back. Maybe add a 16 ft car hauler to put the Honda Beat and 3 whiller on....
No just an aftermarket oil dampening system, it does something beneficial with the tonearm resonance, also makes tracking bad warps a breeze. And I gotta buy a dust cover now.....
That's how you balance Gray/Micro-Trak tonearms lol
I still have that Ortofon Concorde with an OM10 stylus on it, I may grab a 20 or 30 stylus for it, and there's also the new Concorde Music Bronze that looks cool.....
