Audio Horizons TP 2.0 Preamplifier

Well, I finally won a cheap old tube tester on Ebay and I'm glad I have it now. When it arrived a couple of weeks ago, I tested my Siemens Cca tubes and although they both measured over 85% good, they both tested gassy. I bought a NOS pair of Cca and both tested great with no gas and the sound is much cleaner and musical. I had known that something wasn't quite right and was trying to blame the cables or AC. Before I got the tube tester, I even shipped my preamp back to Joseph and had to pay him $25.00 to tell me that nothing was wrong with it.

Sherod i feel your pain. My buddy has a tester and it proved i had the same feelings as you with the degeneration of sound in my system, 4 shot very expensive CCA tubes. The Siemans CCAs are getting so darn expensive that i'm going to try something different. I have a pair of Telefunken PCC 88 7DJ8s and a pair of VALVO Hamburg PCC88 7DJ8s on the way. Its really getting hard to find 60s CCAs anymore for a price thats anywhere near reasonable. The Russian rockets do please the ears but cant approach what CCAs deliver IMO. Have you are anyone else tried any other tubes that can be recommenced with AH preamps. My AH preamp is the first tubed piece of gear in over 40 years in the hobby and tube use and differences were the reason i resisted. It seems that one triode gets worked out hard in our favorite preamp does that seem about right or is it the design.

Oops! I meant to say $45.00 /each for the Gold Lion Genalex tube.

Thanks Sherod for the link would like to hear from those who have tried Gold Lions out. On the CCAs maybe late 70s and 80s versions for 150 to 200 bucks. And in my case those issues of the tube are no way as good as early 70s and 60s versions the Rockets beat them. Please let me know if you have a source for 60s and early 70 for that price.
