[Amps] 4cx1000a for ssb

[VK3HE Craig]

If you concerned about IMD use the  4cx1500B. At low screen potentials it 
has a good figure of -43 db below one of 2 tones. Nothing would prevent you 
using the full screen potential with output power and IMD figures being 
similar to the  4cx1000A. The radios IMD will always be greater than the 
tubes IMD, unless you using something like  the FT1K5 in classA. These days 
ALC design faults are more responsible for bad IMD than the  below average 
IMD numbers of the radio.
