They are very similar but not identical and the amps will more than likely sound different - but should work with no problem (no guarantees here). The 6GH8A's were not the kit "originals", the 7199's were; but because they became scarce the sockets were rewired to accept the 6GH8A. These tubes are still available and are IMO the best driver tubes for the st-70.
Instead 6GH8A will be possible ECF-82/6U8A
Hello Folks!
I receive a few "Ulton" branded ECF-82/6U8A drives, which I want to be 100% sure that CAN BE...?, used instead the "Original" fitted 6GH8A tube in my also Gifted Dynaco Stereo 70 Series 2 power?
