He is asking about a PAIR of tubes in an amp he is looking at.
One option there is that other tubes in the 4X150/250 family can be used 
that offer much better IMD

For many a $700 Chinese 8877 is not an option.

## I stand corrected.  A local buddy built a single 4-250A  for 6m. 
Another local friend  built a single 3-500Z for 6m...and wiped out
every 49 mhz cordless phone for .25 mile radius.   Both those amps
did just fine on 6m. 

## My understanding was the 4CX-250B has sub par imd ?  If that’s
the case, why use it.   I don’t operate 6m..so have no clue how crowded it gets
on ssb.
