Roger - that's clearly true but it's better built than most of them
were. When I lived in western Nebraska, a buddy used to hang out and
go boating with the guy who was pictured in ad for what was then a
correspondence course from Cleveland Institute of Electronics (now known
by the fancier term "distance learning"). He was pictured in front of
his airplane and service van as an example of the kind of success one
could achieve. (No one pointed out that his actual success came from
skirting the FCC rules).
Here's a scan of that ad, from October 1967 Pop'tronics:

His name was Ed Dulaney and he was the "D" of D&A Manufacturing, a
purveyor of CB linears. Most of the area hams were embarrassed to have
a maker of illegal amplifiers in their midst but it was a real boon for
a local electronics distributor who'd occasionally pass along savings on
overstock parts they supplied to D&A. I remember several guys building
multi-sweep tube amplifiers using parts obtained that way, probably
following the many plans that appeared in ham magazines of that era.
When sweep tubes could be bought new for a buck apiece and sockets were
probably a quarter, the economics were favorable ;-) The D&A amps
weren't nearly as shabbily built as some of their competitors, and I've
converted one of the small ones for ham bands. The big joke was in the
70s after FCC cracked down and they had to cobble up the ability for
them to oscillate so they could be sold as transmitters, rather than
linear amps. It wasn't long after that before the company disappeared.
I haven't fired up my Galaxy 2000 for some time, but the SBE companion
amps for the SB-33 and SB-34 were similar (but with fewer sweep tubes)
and they both work fine. I often talk with a buddy in South Carolina
who uses a Galaxy 2000 with excellent results on 40 meters, usually on
the low power setting.
