Hi
I run them in a Citation V and they have held up just fine for a year. I also put a pair in an old guitar amp that I rebuilt for a friend and he just loves them. I cannot remember the exact plate voltage on the Citation V, but it is in the range of 450 v and I know I run the tubes at about 45 mA idle bias current. Guitar amp was lower voltage and cathode bias and I recall setting the tubes at about 40 - 45 mA, somewhere in that range. Tubes have run just fine in both for quite some time. These are the 1970's coin base. Only issue was the box of 10 I bought were all over the map for matching. I matched them in the Citation V and I must have gone through 7 or 8 of the 10 tubes before finding 4 that were reasonably close. I must have tried 4 or 5 of the remaining ones to find a close pair for the guitar amp. All tested very strong though. However, at roughly $6 - $8 each if you buy 10 you can afford to do that. They sound great. At Mike Samra's urging I dropped 4 of them into my Citation II. I biased them to about 45 mA. They sounded fine, but were not in the same league with the Gold Lion reissue KT88 in that amp. So, I think they are a steal to replace a 6L6GC in most apps, but they do have their limitations. Well built, cheap, sound good, and will take 450 volts no problem. Certainly a very cheap experiment, but buy at least twice as many as you need unless you know the vendor is matching them for current draw. Then put them in the amp and measure them and you can surely find pairs. If you can get matched ones for under $10 a piece that might be worth it.
cheers,
Don
