Other than the "upgrades" they did on the amp before shipping there are no mods...I just dropped the 120s in and I bias them to the 502P specs and check it with my trusty Radio Shack meter just for the hell of it (a compulsion, but I'm getting better at not burning my fingers while poking the probes into the test port), even though the "ez bias" works well...In fact, now that the KT120s have settled in it sounds better than I noted in my last post, just fuller and brighter. Highly recommended! I bought the 4 "matched" tubes from "Ctech" on Ebay mostly because of their price, and they're on the East Coast so they shipped really fast. I don't think there's anything to risk buying one of these amps as they seem to be an insane bargain for something that sounds this good.
Jolida 502 KT120 tube swapping
Having been told by the nice people at Jolida that the 502 transformer can handle the KT120's "filament requirements", I wondered if any Jolida-philes out there have tried them in either the 502BRC integrated or 502P (what I have) power amp, as they're apparently similar circuits. I'm tired of reading about how groovy the KT120 is and plan to try 'em eventually just to stop the madness and have some extra tubes around.
