Amp Questions

#406841

Post by dougw181 »

I’ve had this little amp kicking around the garage for years now and I finally got around to checking it out. It has 2 MRF475 transistors in it and from what I’ve found online there output is
12 watts (pep) and (cw) and are primarily used for ssb applications. Is this a 24watt ssb amp?
Any help would greatly appreciated.
Thank you! Doug

My guess is it's a small driver amp, I have no clue on the input wattage, it would have to be really low, but output would probably be around 50/60 watts. You are right about SSB, at least that is what I would use it for.

Wow. Those are small. Looking at the Communications Concepts website. They have Motorola Application notes AN-779 I believe. It has all the general information you should need. Looks like the rated amplifier using 2 should do about 20W.
