In Reply to: Killer DAC on the cheap (relatively speaking). posted by Lou S on July 5, 2022 at 23:29:22:
I had a similar success with my VTA version of the Dynaco ST-70 amp. I installed the VTA board in one of my ST-70s a number of years ago, but never liked the results. I tried a few different brands of coupling caps, and several different 12AU7s, or 12BH7s. I populated the board using a variety of well regarded resistors, including Dale RN and Riken, but no matter what I tried, was never happy with it.
After reading for who knows how many times what a bad tube the 12AU7 is (as Palustris indicates) the "what the heck, I'll try it" light bulb finally went on for me. I bought an adapter for the voltage tube socket of the VTA, plugged in a 6SN7, and finally have an amp I can enjoy listening to music through.
