I'm running the High Gain VTA. This runs to standard 3 12AT7 tubes. I found a pair of GE 5965 12AV7 12AT7 Amp Vacuum Tube MIL SPEC 2X Getters. These tubes are clear top with the getters on the side which is somewhat unique.
These tubes a Simular to 12AT7 but with a bit lower gain. I was toying with the idea of trying one of these in the front center of the VTA... I run the ST120 with the 21 step Attenuator option I got from Bob.
The tubes are well built millitary spec.. Big plates.. Look well built. I was toying with the idea of buying these on EBAY and the guy selling dropped the price for the pair from 19 to 15 so I did it. what the heck.
Looking forward to trying the new tube
