Loose the 84 and the 6D6. The 84 has no business in the set. Swapping it for the 76 is a BAD idea. The 77 and 78 do have the same pinout as the 6C6 and 6D6 but do not make good replacements for each other. They tend to oscillate and are hard the stabilize. Stick with the intended tubes.

Vol 1-50 admiring the old set and trying to
figure out what all those squiggly meant.
