Is that United Motors R-1127? .0047 mfd is close enough for .006 mfd, plate cap.
Here is a change so this cap won't cause a problem in the future. Instead of connecting it to ground use B+. Connect the cap between plate, pin #3 & B+, pin #4 on you 6K6 (or whatever tube).
If the cap shorts going to ground it will damage other components in your radio. To B+, sound will stop but no damage.

:Hello, I need a readable schematic for delco 1127. Also, is a .0047 close enough for a .006 on the plate to ground of the output tube?
