ur welcome

Sounds like tubes could be the problem.  If it blows fuses with the tubes 
in place, chances are the hv ps is ok.  The problem with the tubes could 
be a leaky seal or gold-sputtering.  I autopsy more kaput 8873/4/5s with 
gold sputtering than with air leakage.  The best way to identify 
gold-sputtering is with a dc high-pot tester.
