Do a search on 300B from AVVT and if you are interested then drop me an email.I bought a few pair before the company close down.I ve try a quite a few tubes and AVVT are my favorite.
Cary 300SEI & Western Electric 300b
I own the above amp with and am currently using a pair of Sophia 300bs with a pair of WE300bs on the way. Before I get my new tubes, is there anyone that wants to tell me that I wasted my money and there are other tubes better than the WEs or perahaps that my only regret is that i didn't buy these earlier and nothing else compares with the CAD-300SEI??
