Hi,
I know the first question is probably a long shot that someone will be able to answer but the other ones I'm sure some of you tube gurus will be able to answer.
I have a Class A amp with dual EH 6V6GT tubes. I haven't used in a while and I decided to play it a little today. When I turned it on and took it off standby it had a really bad buzz, even with all the controls turned all the way down. I looked in the back of the amp and I noticed one of the tubes wasn't glowing. I switched the tubes to each others sockets and the same tube still wasn't glowing and the other one still was. Does this sound like just a bad power tube?
I live in a kind of rural area and the only music store with any tubes within 50 miles only has Groove Tube 6V6 tubes in stock. Are 6V6 and 6V6GT the same tube? That guy tried to tell me that the GT meant Groove Tube but I checked a couple tube web sites and that's not true. I checked data sheets on the two tubes and didn't see much difference and the guy at the store told me they were the same but since he was wrong about the GT part I don't trust him about them being the same either.
I went to KCA NOS Tubes and they have TungSol reissues for $40 a pair which is a little more than MF but I've bought some tubes from there before and found the service to be great and for $5 I'll go with the better service.
So this leads me to my next question, at MF they had options for Hard, Medium and Soft for the tubes with no explanation of what that meant but there was no option for Hard, Medium and Soft at KCA. What does Hard, Medium and Soft mean? More headroom for Hard? Is Hard higher gain? I googled "TungSol 6V6GT Hard" and got nothing as far as an explanation.
