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!!

I'm not familiar with your amp, but I'm not sure your new wiring scheme is the best way to go about things, especially with a capacitor in the mix.  If you're trying to get rid of the thin plate, I would take those four wires as well as the two coming from the binding posts and solder them all together at a common point.  That would mimic (electrically) the original layout, which your current scheme (as I understand it from what you've written) doesn't.  Also, do you have a fuse in the amp for the high voltage to the tubes?  This would be separate from the mains (AC) fuse.  If so, check that first to see if it's still good -- the vibration could have busted the internal wire.
