[ARC5] Canadian SCR-274N

[Jay Coward]

Ken,
 I had one of those Canadian reworked BC-455's; back in '72 or something I got it from Fair radio. I used a home brew 5Y3 p.s. with pi filter. In '75 I was living on Martha's Vineyard and in the middle of winter, 0 QRM, I picked up a transmission from McMurrdo (sp?) station in Antarctica. Just above the noise floor. Gave me the chills! Antenna was split zip cord about 15 feet strung around the wall/ceiling junction of the room I rented.

Yes. I believe I
have seen those on receivers modified by the Canadians.

I had two such
receivers at one time, but sold both.

The data plate is mounted on the side
of what I would call the top-cover, 
which covers the tubes, but NOT on the
top, flat cover with the 5 
slide-fasteners on it.  It is usually on the left
side of the receiver-cover. There 
are usually two data plates: a larger one
and under it, a much smaller one. 
The smaller one, if it is there, says
something like "Modification B2" followed 
by some circular indicators of some
sort.

If you would like, I can send you a photo of one I had.

Well, if it is
what I think it is, then that receiver is not from WWII. The 
Canadians did the
mods I am talking about after WWII, although I don't know 
the dates. What they
did was to replace all the can-caps with more modern 
plastic-cased jobs,
usually a pink plastic, mounted at angles on boards, one 
board on each side of
the receiver. They also replaced the screen voltage 
electrolytic with a more
modern one, usually in a dark blue case.

I would appreciate your looking at
the photo of the data-plate and telling me 
if you recognize it. Maybe the one
you saw was different, but I suspect it is 
not.
