Will an 35-50 MHz Public Service Amp work on the low end of 6 meters with my MFJ 9406..the mode will be SSB and CW..I have a heathkit amp on two meters and need to toss a switch when I go from FM  to CW/ssb...
and am guessing I might have to modify the amp for CW/SSB.
the amp is a RF POWER AMPLIFIER, Model PA1-1AE,Also assume I will need to retune the amp for the high part of its range..I know others who have used this amp successfully on 6 mtr FM..Does any one have suggestions??

This is a no-brainer.

The PA1-1AE is manufactured by TPL in Los Angeles, which happens to be up the road from me.  I simply called them and asked.  Spoke with Chris in Tech Support.  Their phone number is 323-256-3000.

The PA1-1AE is a CLASS C only amplifier and will not support linear operation for SSB.  It's intended for FM use only.  It's also a narrow band amplifier, 4W maximum input power for 80W minimum output power, and only covers +/- 1 MHz of spectrum, so must be factory re-tuned for the 1 MHz you want to cover.  It's still a current model.
