No bias reading, tubes lit up, no sound

I do not think it is another issue elsewhere in the amp. It is most certainly a grounding issue. Your rewire has upset the original grounding scheme. Go back and match what was done originally. Exactly. 

Did you sort it out? 

Unfortunately, not.  I did fix the short to ground on each pole I caused(too much torque applied on the plastic threads) by using nylon washers so at least now that is solved.  We are presently stationed in the Netherlands and was lucky to find a guitar shop in a nearby town(nothing of practical use from google),whose elder owner once worked for Philips- reel-to-reel machines, amps, and the tube factory as well.  He called me this morning to say amp is ....fixed!!!  Didn't discuss what was done over the phone but the charge is.....280 euros.  Everything is so outrageously expensive here, at least for me.  But I am most happy, anyway.  I meanwhile purchased a Marantz HD Amp1 from Amazon(fearing I toasted the amp), with the Dutch Hypex class D modules, based on its 21century design and connectivity.  I hope I like its sound(as all the reviewers) enough to sell my Cayin although with all the upgrades in it, I have taken it to a few hifi shops in NL, Germany, and Belgium just for fun, and all the salesmen pretty much agreed that they have nothing in their stores under 5-6K that approaches  my amp sound-wise.....  May be a keeper for life, perhaps.
Will post how I broke it(still don't know) and what was done to it when I pick it up tomorrow.

Problem solved.  I must have rubbed the drill bit against the adjacent choke(transformer), which of course was shot...You know that sudden, forward motion right after you have just drilled through steel....Instead of trying to get a new one, the technician has completely rewound the whole transformer with even better wire and I am sure with that old, artisan-like technique as well.  As my system had been down for about two weeks and I have been listening to vinyl only on my second one in the garage( Elac B6, Yamaha R-S202 receiver, heavily modified Rega P25), I need to allow some time for the new wire and posts to run in before concluding whether all this was worth anything at all.  The technician just kept laughing at me as obviously most of the audiophile stuff he takes as just snake oil....But we all know better than that, right?  Cheers!!

Thanks for the update. I have come close to ruining parts as my drill entered the chassis. I get it!
