[BC] substitute driver tube for FM-2.5K ?

[Dana Puopolo]

In a pinch it works, but my experience is that the driver becomes much more
'picky' in its tuning-and unstable.

I have been told that I can use a 4CX250B in place of the 4CX150A driver in
the FM-2.5K (1981 vintage)

Can anyone confirm or deny this ?

Any stories; good, bad or ugly ?

Thanks !

Gary
