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?
