Default Re: Kolster Brandes RV 10 (Crown)

After I posted my comment yesterday, I looked the set up in R&TVS. There is no EHT rectifier heater resistor shown there. However Sexton Mallard says that the winding is continuous at the rectifier base pins and that he can draw no HF arc from the U26 anode (or at least that's what I think he's saying).

Do you know that the overwind is continuous? Although if it were open, I'd still expect to get some glow from the U26 filament. I assume the line output valve isn't showing any signs of distress (red hot anode or screen grid, for example).
