[Amps] Even more power solid-state amp's

[Will Matney]

What if you had two final tubes, one idle until the other gave up the ghost. It's easy to change over the same way with way less circuitry. Personally, I dont like cramming all those solid state devices together that way when 1 tube will do the same. Actually, like I mentioned above have two, one being a spare to be switched to. They have made them in that very setup so I cant see any benefits to the solid state over the tube. All those cards and the interconnecting wiring inside the cabinet is like trying to cram 10 pounds of s#it in a 5 pound box. When or if they ever make some large semis that you could run one in place of a tube, then that would change my thinking. Now, I dont think any of the "bricks" made today operate anywhere close to the RF range. Powerex makes some big semis but still nothing in this freq. range I dont think.

Best,

Will
