There was a town named "Mars", near the location, where I seriously mis-spent my youth. (It is reputed to be the only town of that name in North America, or perhaps anywhere on earth).
The lettering on the back of the local trash pick up truck states "Satisfaction gauranteed or double your garbage back".
I often wonder if anyone ever accepted their offer?? Perhaps not a bad idea, if the contents were electronic throw aways, such as SX-28s, etc?

Rather than get up from the bench to
go get a new tube, I'd try swapping the two 2C39s. It
always irritated me when someone else had already done
In high school, I had my own little business taking care of
several companies' spcial industrial radios. I hated
the radios in the "fix other trucks" trucks. It never
failed that those radios would be coated with gear
lube. Not only is that stuff sticky...it also
stinks... and it transfers from item to item just by
touch. I finally made a radio washer & dryer to
get that @*~,-":@ lube off the radios. I was glad that
those radios never seemed to break very often.
That work helped me escape engineering school with no

The Motorola T-44A- series used one 2C39 as a tripler/driver
and the other as the final amplifier. Towards the end,
Motorola started supplying 3CX100A-5 / 7289 tubes instead of
the glass 2C39 tubes.
During my junior year at Georgia Tech, when I worked for the
Motorola Service Station in Atlanta, Georgia, they had a
service contract with a garbage pickup service that used the
T-44AAV-3000 series equipment. Being "low man on the
totem pole", I usually got the "honor" of working on those
units. I swear that the drivers had more, well aged,
garbage in the cabs of the trucks than in the back!
After working on some of those trucks, everyone gave me a
Boatanchors mailing list
