A good reasonably priced 6922 that has good balance top to bottom, is quiet, and doesn't get alot of press is the Japense made Matsushita. To my ears, they sound better than the new 6922's being manufactured today.
Tube rolling 6922 tubes looking for transparency
I have a sunfire classic vacuum tube control center pre-amp that uses 3 stock sovtek 6922 tubes. I am looking to tube roll to a tube that is (reasonably priced) with a little more transparency and air! I tried tube valleys recommendation of Jan-Phillips low noise 6922 and it was more transparent and would have been perfect but apparently this is one of the pre-amps that has a microphics problem when using these tubes. Does anyone have experience with a (reasonably priced) 6922 that’s a little more transparent with a little more air than the stock sovteks!
