[Amps] Shelf life of 3CPX800A7 tubes

[Barrie Smith]

The 3CPX is a direct drop-in replacement for the 3CX.

Usually more expensive, too.  Do you have a lower-than-3CX price for them?
If so, let me know!

The advantage of the 3CPX is it's higher plate voltage capability.  I run a
pair on 432 with 3300 volts key-down.
