https://www.qsl.net/kp4md/henry_30a02.htm Try #2 to post this, and not have Firefox crash and Windows update at the same time. Anyway... I bought one of these 'lil VHF commercial High Band amp at a Horseheads, NY Mini-Fest, back in the late 1990's for like $20.00, when the fest was at end and vendors were doing last minute close-outs. Hey, the parts were worth at least that. However, I've yet to power up and put RF to it to see if it even works, and to also see what FREQ it was tuned-up to. So, in a storage bin it's sat in for like +25 years. I did try a search for this amp over 20 years ago on-line, and could find nothing about this amp, at the time. Well, a few weeks ago, while searching for something completely different, that preceding link came up. (Well, COOL!!!) Not only that, but apparently, Henry Radio is still around today. https://www.henryradio.com/ Anyway, back to that Henry 30A02 Amp, it looks very straight forward and has a nice filtering section. Better, than like Ramsey, or Mirage, amps do. So, if you have one of these amps, and an RF spurious HT, like those early Beofangs, this would be an ideal amp to use on it. Anyway, good INFO, I believe.

Yes, Henry Radio is still around but not in the ham business anymore.
Their ham stuff was very well built and I found them to be quite reliable. We had one of their 2K Classic amplifiers at my university club station.
The thing was very rugged. We used to beat the snot out of it with lots of SSTV and some of the guys would contest with it and it just kept coming back for more.
