On the VTA amp pages, you might find the link to the 'diode fix' for thiese.
A 1N4007 on each leg works. Problem might be that when these were supposedly built? House current was closer to 110 than todays near-120. That puts higher than expected voltage TO the tube which may be the source of hte arcing?
Check out hte diode fix.
