The 1meg grid leak resistor on the 76 is quite a high value, although 9 pin valves are OK with this I don't recall the 76 details, but reducing it to 500k wouldn't harm anything else, but would suit the valve better.

Just FYI, the RCA specs specify 1M as the maximum value. As Paul says changing to 500k wouldn't hurt, especially as the RCA specs probabbly didn't expect the valve to be used 60 years later.
