You are correct. i used one for years and never had any problems . I did
later put 3b28's in place of the 866a's and added 12 more mf to the supply
if i recall. I now have another one that i got in working order. just need
to recap one of my two low power BA's to use with it. or build a swamping
pad for the Globe 680A.

The Thunderbolt was easily driven to full input by 20 watts. I recall it
was easy to tune and very sensitive due to grid drive. The grid was
swamped as I recall, so it was also very stable.

the Johnson Thunderbolt is a AB2 amp that uses 4-400A's check out this amp
i think you might like the layout it uses a roller inductor instead of a
varicap.
