I am running on the last fets(<10) for this amplifier.

1w in, 40 watt out. 32 volt 3 ampere

due to very low demand for this amp i never updated this page.
in the beginning of my amplifier work i used wrongly calibrated attenuators which led to wrong measurements.
all this has all been corrected for all my amps except for this amp.
but recently i made a new pcb with which 35watt p1db is possible at 32 volt and 45 watt saturated.
when i first designed it i was never interested in ssb work and so all the measurements where done in saturation.

the amp is 160 euro version mounted inside an alu box.
