Thought you guys might want to see my latest radio restoration. Its a
rare
1935 Tobe Deutschmann Browning 35 Shoertwave receiver. It came in either
kit or factory assembled.
That's a beautiful set! Nice job! I like radios of that vintage too.
Thanks. I'm hooked on radios from that era. The one radio Im still in need
of is the RME-9. I know. Good Luck!
Does it use the Type 35 tube, the first screen-grid (tetrode) with
variable-mu,
for AGC control? That seems like a logical place for the "35" to come
from.
No. In 1935 most receivers started using the new metal octal tubes and this
is one of those sets. I think Hallicrafters SX-9 was the first to use all
metal tubes. I'm still reserching this set but it may have been the only
kit that year? There were several versions of the Browning 35 if you look in
Raymond S. Moore's books. This one is the metal tube version and it has a
factory 6E5 tuning eye and he makes no mention of this set with that tube.
The tube lineup is as follows- 6K7 RF, 6A8 Conv, 6K7 IF, 6K7 BFO, 6H6 Det,
6F5 AF1, 6F6 AF out, 80 Rec. The one in Moore's book show a 6C5 as BFO?
Also, how does the dial pointer work? The ad shows a simple external wire
pointer in front, but there's none on your set. Is it just still missing,
or
is there a lighted shadow pointer behind the dial? Some sets of that era
used
this very sexy arrangement -- I had a Freshman-Belmont with separate AMBC
and
SW tuner chassis that each used that type of dial pointer.
Yes it's a shadow dial. The bulb follows the needle.
There were some discussions a few years ago about who made the first
band-switching RX (no darned plug-in coils). Yours must be a contender
for the
title.
The Lincoln R9 I think was the first in 1933. By 1934 most of the main
contenders had bandswitching. Sargent,Postal and RCA had receivers that
didn't still. Most of the main mfgs had receivers with bandswitching by
1935. The Browning uses the prewired Tobe tuner with band switching for ease
of construction.
Say, how about some chassis shots? Pant, pant ...
I'll post some by next weekend.

73 and good DXing.
