He is not a ham but when he gave it to me, I thought maybe it would be a ham amp converted to CB. No such luck on this one.
I'll keep it for chassis and other parts for my homebrew projects. I might use the parts that I can for a homebrew transmitter. Nice looking cabinet it came with and a few other parts that is in it.
I was hoping I could find a schmatic for it but no luck on that.
VERY EASY for a Novice to ID .... No Multi-band switching, poor construction, assembly, RF keying (because CB radios could not remote key amplifiers!!).
It has a metal plate on the back stating it can't be used on the CB bands.
That was another Quick CON game ... there were less than TEN amateur radio HF amplifier mfg. in that period. They are recognizable brand names with long histories.
There are tens of thousands of these illegal CB amps made in late 1960s / early 1970s.
Deaths, estate sales, hard economic times have produced thousands on Craigslist, eBay, flea markets -- but no $$ -- NOBODY wants them, especially on 10 meters.
The 6LQ6 vacuum tube was made for TVs as a Sweep tube, very cheap before solid-state TVs in 1970s.
Sweep tube mfg. in USA, an Western Europe closed in 1981. You surely remember that time period of rapid technology obsolescence.
Diagrams and circuits were adopted (some poorly) from 1950s and 1960s Amateur Radio literature.
Parts salvage? Throw out the capaciors and resistors. You are left with a chassis already punched and maybe a good AC transformer of unknown ratings.
Metal scrap prices have risen faster.
