[Heathkit] Suggestion for legal limit AM amp (was Heath Warrior as an AM amplifier)

[Carl]

AL-1500, Palstar HF-2500 or 2500E, Any LK-800 model (A, C, TNY, etc), 
QRO-2500 or 2500E, LK-550, various Henry's, Alpha 76/78 family with 2X 
3CX-800 mod, and likey a few I missed.

The T Bolt is a bit weak in the PS for extended old buzzard transmissions 
from what Ive heard on the air and read elsewhere.

A pair of 4-400's has 200W less Pd than a pair of 3-500's.

An old HB 4-1000A amp will easily do 2500W Class C AM at 5KV so it has 
plenty of scrote as a QRP linear with less voltage.

I would suggest a Viking Thunderbolt Amplifier. I use mine almost every
day on 75 AM with a resting carrier of 375 watts. I drive it with a
Ranger in the resister position and I don't need an attenuator. With the
DX100 you would probably need to use an attenuator between the exciter
and the TBolt. I monitor on an SB610 and it looks and sounds great.
