>From Winstips:   DEAD
I found a low ohm short on IV01 pin 36.   ( B+ to  jungle IC) #257805
Replaced IC and short gone but still dead.   Removed solder from C of  H-out
and scoped it.  It had a nice horz waveform there then hooked up to IHVT and
Waveform gone.  New IHVT repaired the set. # 257805 on this set.  P Hull
