[Amps] Dedicated RF

[Gary K9GS]

Exactly Carl....there are still plenty of 3CX800 tubes floating around 
and pulls are fine for existing amateur equipment.

Heck....if I came across a good deal on an amp that used 3CX800s I might 
be tempted to buy it.  Buy a couple of pairs of spare tubes and I'd 
probably be set for my lifetime.  But I wouldn't rely on an iffy supply 
chain for new production.  Just think about TenTec and the 4CX1600.......

I thunk the 3CX3000 is an excellent choice...plentiful in the supply 
chain and a market exists outside of the amateur radio market.

Does anyone know if there is a market for the 3CX800 outside of amateur 
and replacement for MRI?
