There you go doing exactly what you complain about in 
others. I've built dozens of six meter and near six meter 
maps over the years, including 3-500Z's and even sweep 
tubes.

If someone wants to butcher a good SB220 or SB200 and 
convert a what was reasonable HF amp to a monoband amp that 
will always be on the edge of stability that's fine, but 
let's not pretend the RF layout and tubes in most HF amps 
lend themselves to being great VHF amps.

Saying something isn't the best choice isn't the same as 
saying something can't work. It's simply saying there are 
better options to consider.
