Hello Steve,
Yes, the 4x150 and 4cx250 operate in similar circuits. With the obvious
differences in anode capacity, the 4cx250 has slightly higher values of
internal element capacitance Cin, Cgp & Cout. In >VHF service direct
interchange is not as straight forward.

:Hello all,
:Just a quick answer will do.
:Does the 4cx250b have similar operating characteristics to the 4x150? I
:know the difference between the glass and ceramic, but have a chance to
get
:a couple new, sealed tubes (250's) and the only thing I could possibly
use
:them in is some old Collins thing, a KWS-1, I think.
:Just a thought.
:73 de Steve, NR4M
