Yes I am lucky, but that is actually how we met. I was visiting my Moms 50 years ago. I started to leave and I heard the new Jeff Beck playing. I went around the corner and there were 4 gorgeous ladies dancing (doing the bump BTW) sharing wine. I looked up, Thanked GOD, and joined right in. I was fresh back from working on the Island of Adak in the Aleutian chain with pockets flush of money.. ;-)
Yes, mine were all pulls from Macs through the years. Of the 7 12AX7s a C20 uses You need 3 if your not using the phono section and only a pair for the section your using.. You don't have to burn up valves for no reason..
Ok there are a few different brands that are still Telefunken too. Just do a little research. 10,000 plus hours is not uncommon at all. Make sure they are matched and above 50%. Tell the person your looking for "low noise and matched" and that YOU will check them.. I always get pairs if I can, singles, I pay less..
A EC88 is a 6922, not the same, very close though.. I don't use 6922 to often, BUT they are a great valve. I think they have a little higher gain. I can use either in my Carys, just not sure with Macs. You want EC83s. Mullard Blackburns are right there too, one of the best valves ever made..
