The innards of that AK 20 Big Box set
#20

Don't feel bad I do it all the time!!! Resistance isn't critical it does need to be fairly low you could put a jumper across it and see if it works. That resistor is in there to limit the grid current so the tube doesn't oscillate. (that's how they accomplish neutralization)
Should drive the E spkr fine.
