Biased AB for SSB? I'd say close to 250W - but that is what it's label would say...

IF you get that, for SSB modes - on carrier like AM or running FM you'd be lucky to have 100 - 125 W or so on the carrier side....

The Ferrite design alone is for 200+ watts. They are also Morotola "Blue Dot" - a match set scheme but still references to "red - dot" matching. Quality issue - don't let it go to your head and don't blow it...

More than likely these are MRF454 - so you'd see 80W max out of them...good find though - these babys can handle Swing - because they are made for SSB modes (note simple 4001 style diode in 1st pic on power bias rail on the top of the photo simple AB bias) can handle the input dynamics (impedance range to power level input swing) a little better than a 60W 455...so they don't have as "narrow" of a window before your "pinch up".

Note the winds - 3 to 3 - so the amp may fight you a little as far as SWR is concerned not a biggie. But, as othrs are telling you, again keep the power level low - you should be ok. But, run a Limiter (keep it in place) though - that is a low-level drive amp. To run an amp like this for say a PC-122 or SSB ducky - you'd set an SSB radios ALC to about 8~10 watts to keep it from cooking burgers on the grill...(tarnish)

it does have a delay so you may need to look it over and see if remote key is a better option...More than likely the switches focused on RX and SSB delay as well as TX power.
