Here is a transmitter I am seeking information on. This radio came from the estate
of an ex Stancor Chief Engineer, Edward Kelly W9HPD. I have never seen an advertisement
for this transmitter in the magazines nor does it appear in any of the current vacuum
tube transmitter books (Rippen or Moore). By the model number assignment I'd place
it at around 1946 for time of manufacture. I base this date on the fact that the
ST-202A was introduced in 1947 and the ST-203A in 1948. These last two transmitters
were advertised extensively over many years in the ham magazines and I own both
of them. I'm beginning to believe that this model never made it to formal production
and perhaps this is one of few prototypes created. One important fact that leads
me down the prototype path is that if you look at the close up label pictures of
the front panel you will notice that it is paper! This paper is glued on the metal
front panel. You may also notice that there are some white circles around the edge
of the paper that appear to be hole guides for the panel mounting screws. However,
the mounting screws are located at other positions and end up going right through
the manufacturer and model labeling. I don't have any paper work on this transmitter,
but here is some information obtained from visual inspection: Weight - About 75 lbs. So now my plea! If you have any knowledge of or information on
this transmitter please email or write me about it. I'd sure hate to have to trace
out the entire circuit, but if need-be I'll do it. One of my first duties will be
to remove the front panel and scan it into a computer. I want to dupicate the front
panel onto a better and washable milar film. I will not destroy the original, but
create a completely new front panel and keep the old one stored away in a secure
place. This will also allow me to move the labeling down that is currently covered
by the mounting screws. |
