Hi Steve,

You have a late 40s demodulator, possibly for use in a TV station. It would 
have been connected to a video monitor and audio amplifier. The continuous 
tuner was used by DuMont from 1947 to about 1951.

It looks like the tube sockets are riveted in, so it is a factory made unit 
rather than a kit. Often wooden cabinets were used in TV stations where the 
equipment was in an executive's office. We have a late 40s studio monitor 
like that:

I'll send it on to a few friends to see if they have any comments.

Regards,

Steve

Hi,
I'm a memeber of the New Jersey Antique Radio Club and am looking for
help. I sent the note below to our email reflector since we have a few
TV collectors in the club but didn't get a hit. I am hopeing that you
might be able to tell me if the pictures are of an identifiable kit or
magazine construction article. After looking at the bottom of the
chassis I found that the electronics assembly was several levels below
the mechanical work with parts placement and soldering somewhat sloppy.
This doesn't fit with the quality of the mechanical work.

Hi,
I picked up an orphan TV Receiver this weekend (of course I went to the
flea market didn't you). I has an inductotuner or continuous tuner I
believe they were made by Dumont. It tunes from  channel 1 to 13 (50-216
mHz or so). The set does not seem to be a piece of production equipment.
To me it appears to be a prototype rather than a homebrew I haven't had
time to take the chassis out of the cabinet yet due to snow related
duties. This is a guess on the way the tubes and IF cans are mounted.
When I get the chassis out I will be able to see if some of the odd
shaped holes were done with a punch or not. The sockets are mounted with
screws not rivets and there are no indications of a manufacturer.

The interesting thing about this set is that it is a TV receiver not a
TV (i.e. no CRT). There are four controls sensitivity, on/off, tone and
sound; plus the tuning. The back panel has multiple UHF connectors,
antenna in and at least two video out plus audio terminals. The tubes
are a mix of octal and miniatures and the wood cabinet has the look of
1940s TV construction. The top has a two level rounded section so it
wasn't stackable.

Anyone have a clue as to what this is? It would look like it was built
for home use rather than studio at least the cabinet is. Could this be a
re-boxed piece of broadcast equipment if rebroadcast receivers existed
in the late 40's. Also, does anyone know an exact date range for the
Dumont tuner? I think they kept channel one on the dials for a year or
two after 1948.
