4th of July in 555 2nd IF can
#6

Look for the origin of the sparks. Have the chassis on it's side if necessary and try to locate where it is coming from. It sounds like you either have two leads touching that shouldn't be or a lead grounded. B+ goes through the IF can to feed the plate of the previous tube.

Yes, good idea to go where you did work and look there.
