[AMRadio] Ferroresonant transformer revisited

[John E. Coleman (ARS WA5BXO)]

I'm sure you realize that a pair of those tubes is capable of up to 3600
watts plate input and 2700 watts output with a PEP of go knows where in
class C.  But with their 900 watts plate dissipation capability, they would
make a cool linear. Just drive the grids with a 50 ohm load on it.  If you
do that instead of GG, I would still neutralize some how.

I've got a nice plate transformer that will kick out 3800 volts, but I 
don't think the current rating is over half and amp.  I'll look on the 
link you provided and se if it's feasible for me to even dream about 
this one.
