Ok here me out on this one. You have the schematic. The company is out of biz. (check for IP with a Lawyer) You, Jim, and Ape could team up with PCBway to do a Toads Amp!

We could! There are plenty of "reference designs" out there too

I have made some Wago to Power Pole things, I put a DPDT switch and a fuse just because I could.

why just do it like the muggles when you can overdo it like a ham!

Love the "does it work" format. I think that the "can we repair it" format would be a banger as well. Thanks for the video!

Thanks! I have fun with these too!

They don’t make them like that no more it seems, my big 2m amp 25 in 300 out, modern ones more like 25 in 80-150 out. They probably could even withstand a nuclear blast.

Good morning! Question: I’ve been watching Hobbyking a while for 2mm gold plated banana connectors but always sold out to use for antenna links. Would you have a recommendation on a high quality source?

@temporarilyoffline 2 ай бұрын

I just grab my banana connectors from amazon. These are the ones I use: geni.us/P2VC8

If it ain't broken don't fix it! You may end up having to repair it. Nice video Steve! 73

Great video Steve. Brought back old memories. You should find Water Street, Binghamton, NY somewhere in that manual. VHF Engineering was founded where I grew up. The owner was a local ham and very active in the local clubs. They made an HT, repeaters, and other VHF equipment and accessories.

Their is a lot of them old amps around. some 30 to 50 MHZ . That one biased for SSB. and AM . you could hook a IC 705 to that .2 meter AM and SSB. may be fun. I would run that 50 % power on 2 meter FT8 . The VHF/UHF 2 band ones came out later . That amp has band pass filter so only 2 meters will pass thru and work. I got a small 2 meter/ 70CM amp that FM only . think it 75 watt with 5 watt in. has receive amp . and the LED changes color for 2 meters/ 70CM . auto band select. I got at local hamfest some years ago. cheap told me only worked on 1 band. I tried it, works both bands fine. I got several others but that the only 2 band VHF/UHF I got . The recieve amp is a LNA and works great. but not for Baofeng . it over loads the front end. If you are cold , I got a 2 meter TUBE amp. 1.5 KW SSB. 240V . makes lots of heat ! It gets the MFJ dummy load so hot you can cook eggs on it. and that 30 second keydown 1.5 KW FT8. 73

I love old gear!

LOL... I keep holding my breath every time you keyed up, expecting some 35+ years old component to let the smoke out. For giggles and curiosity, I wonder what that amp would have looked like on a Tiny SA? No tiny surface mount stuff here... good old fashion stuff that old eyes (like mine) can work on without the aid of a soldering station equiped with an electron microscope. 😁

I'd start with dirty in likely dirty out, I saw no filters. I wonder if it would make a clean signal dirty. Next time!
