croft Troubadour issue

My Croft Troubadour OTL fried some resistors.  I took it to a great tube repair guy who has worked on some other amps for me.  He reached out to Glen Croft via email for some advice and or a schematic.  Glen was not helpful stated that he had no schematics for his old amps.  Does anyone have advice or direction so I can get this up and running?  Thanks for feedback/support.
