NO, it wont do SSB as it's class E and not linear.
I'm not interested in SSB, fine for comms, crap for tunes!
Sure tho' the design uses parallel FETs, voltage however would be the same, you need lots of volts to keep the losses down.
More FETs = more current = more power however.
The parts are not that expensive, a FET pair can only be $20, it's more the time designing and testing + the meagre amount I will sell (50?) which will drive up the cost.
If someone said 'Build me a 100' that would halve the cost immediately!
