  1. Well, I hope my new tubes are good and this never happens again. ;) Maybe I try it one of these days.
  2. So it seems there are two versions. I'm sure my values are correct too. Specially C25, I know it well because it exploded two times because a deffective tube. The idea about the dwell control looks interesting. I played with R31 value (put a 4M7 pot in parallel) and it did nothing, but now I guess changing both resistors for a pot as you suggest should work... My 4 last digits: 0059.
  3. Hello. I've updated the schematic to adjust the values of C6/7 (150p) and C25 (22u). I checked the other components and are all ok. Here's the schematic and component list checked one by one.

  4. Try this: increase R32 from 100K to 330K. Happy new year.
