I presume you mean 6s7b. I had plans for using one of these for an oscillator for a superhet but, after building a test circuit using a fet, I am holding off at the moment as there are more impotant things, and I do realise that the fet will likely be more stable. A valve circuit would give more drive though. The 6d6a I have used but only fleetingly. It is a signal diode giving response similar to half a EB91 when I tested it.
