Bought this yesterday locally. Was pretty excited to get what I thought was a 2 pill amp (from my google searches) thinking 100w pep on ssb here we come! Opened the covers this morning to see its a single pill MRF455. Most of my online searchs show a more modern version I think from the early 80s with black face 2 pill.
I think this one I bought is older then that? Anyone ever seen one like this? Thinking maybe 60watt pep? I only want to use it on ssb. There is no ssb switch but I see a 22uf capacitor that may be related to stopping relay chatter. I think the amp is AB class? Thought I'd show you some pics for interest/comments:

Thanks for the comments guys.

Shadetree Mechanic: Just confirmed what you said with the input transformer grounded. Oh well class C it is! Thanks for letting me know.

I'm really good at buying stuff that just isn't quite what I'm after. It was cheap enough, paid less then what the MRF455 is worth alone. I'm thinking if it sounds bad on air I could repurpose the transistor to my HR2510. I seen a high power mod online using a MRF455 as a final substitute.
