No bias reading, tubes lit up, no sound

Just replaced the generic brass binding posts and the four connecting wires to/from the output trannies on my Cayin TA-30 tube integrated with Eichmann Pods and Furutech Alpha OCC wire but amp is not playing music now, another set of tubes didn't help.  I had to slightly enlarge the holes for the new posts.  I also got rid of the soldered thin plate connecting/shorting  the two negative posts, on which  were soldered a total of four black wires-two from the output transformers, one from a ground screw, and one coming from a power supply cap. I soldered  them in twos to each terminal and then soldered a short piece of the Furutech wire between the two posts.
Did the vibrations from the drill caused any damage, or is the new four black wire connection the culprit?  I am no technician so I thought to ask for help if anyone could point to a possible remedy that would save me a trip to a qualified service, in which case my system will be down for what would feel like forever.....Thank you so much for your input!!
