I have plenty of NOS 6GH8 american tubes for sale. Any brand preferences? To use them in place of the 7199 you may actually rewire the original driver board.

The have plug in adapters to use the 6GH8 in place of the 7199 tubes so you can use either tube

You got any RCAs? I can probably get away with “lesser” 6GH8s because the Dynaco probably doesn’t run them above their ratings like TV sets do.

The 6GH8 tubes work very well in a ST-70 using the plug in adapters, I personally think they sound better than the 7199 tubes
