How would one wire up a 6SB7 to replace a 6A7? I've looked at the grid configurations of the 6SA7 and 6SB7 before, and I can't figure out how to make either work in place of a 6A7 or 6A8.
With the 6A7 and 6A8, it is obvious which pins to use for the oscillator "plate" and oscillator grid. With the 6SA7 and 6SB7, it is not so obvious.
Detailed directions would be very much appreciated.
I'm sure others could benefit from this knowledge also.
