Hi,
I think you damaged the tube. Are you inserting the damaged tube back into the socket after replacing the resistor?

You might want to get a good tube and try it in the side of the amp that you inserted the worng pin and see if the amp and the good tube operate normally.
I would guess that the tube that you inserted wrong is as good as a goner. If the amp work fine after replacing some resistors as you said than consider yourself lucky.
By the way what amp and tube you are using anyway?

Take care,
Buddy
