Over the week end, I received and installed new tubes for my VAC PA 35.35 amp. I had ordered from Brent Jesse a matched pair of Telefunken NOS 12AU7's, and a matched quad of Mullard reissue EL 34's (new stock). After a thorough cleaning with Deoxit, ProGold, and a coating of Mapleshade SilClear on the tube pins, I was ready for some listening. After biasing, right out of the box, I was astounded at what I was hearing. I couldn't believe this was the same amp. What a jewel this old amp is, I had no idea it could sound like this. I am still a relative Tube Nube, (the VAC is my second tube amp), so I didn't know what to expect, I was hoping for some improvement, but not the vast increase in every aspect of performance.
I won't be buying any more EH tubes, I found that out. Just thought I'd share, this was a very good day, audio wise.
