[Amps] Thunderbolt Linear amp

[Bill Fuqua]

	Has any of you tried some easy improvements to the old Johnson Thunderbolt?
I just got a parts unit that I plan on restoring but I may not make it 
original. One thing that
strikes me is the low plate voltage and the small diameter wire on the 
roller inductor.
  I suspect the output component ratings voltage and current may be a 
limiting factor.
	A full wave bridge rectifier would be an easy way to increase plate voltage,
if bypass and plate tuning capacitors allow. However many of these old 
transformers do not like
having their center tap  floating at high potentials.
