Need Recommendations for a New HF Amp
 

My trusted Amp Supply LK-500ZB got damaged after a lightning strike. I am
looking to replace this HF amp (which used two 3-500Z tubes).

Any recommendations for a new legal limit HF amp?

What about the Amritron amps?
The AL-82 uses two 3-500Z tubes.
The AL-1200 uses a 3CX1200A7.
The AL-1500 uses the 3CX1500A tube.

In 10 years time, which tube will be easiest to get?

Any other manufacturers I should consider?

P.S. Since I do a lot of RTTY and SSTV, I am staying away from the solid
state amps.
