I have been offered channels from a butchered Trident S80 console, the price is approx 450 USD (3750 sek)

Anyone ever crafted a rackmount unit of a channel strip, and what do you need? PSU for 48 V, amp PSU, casing, connections? Is the unit ruined if there's oxide in the pots?

And what about the price tag?

I've got some skills in soldering and basic electronics, but what do you think? Lots and lots of work?
