I think that I may have found the answer, these two tubes are NOT really substitutes for each other, at least according to the RCA specs I found.

The interelectrode capacities are different Whilst the input capacitances are close, 5 mmf to 4.7 mmf, the output capacities are way off, 6 mmf to 11 mmf. However it looks like a 6C6 is interchangeable with a 6D6, but that doesn't really help here, I wonder if a type #78 might work though?

Arran
