What do you mean “digital” noise?
Also on the 3000, the filtering, feedback, and gain around the A/D/A are analog, unlike newer devices
I wouldn’t trust many techs poking around in a 3000, you want a guy who can do the job right and who knows the schematic/operation well who can get in and get out with the lightest footprint. But if this sounds like too much trouble/money, I’d probably take it off your hands for you…
