The Fine Things are Always Hand Made
Hi to everyone, I have been delayed with following up on this for quite a while. I had covid late 20 into 21 so I was out of action for a while. I was in the hospital twice. blood clots and pneumonia in my lung. I thank the Good Lord he kept me alive.
Anyhow I got into the garage today The chassis for this cabinet appears to be an allwave 12. Nine tubes, the funny thing is that there are 5 control knobs mounted in the chassis. all strait in a row as you see in the cabinet. The tuning knob and band selector are above these 5 knobs. There are also the 2 small switches that were mounted at the top of the wood dial face. The serial number on the back of that chassis is F-193. on the bottom of the chassis a paper sticker is dated 10/30/45. right after the end of ww2 . so what this is, I don't know. maybe something put together just after the war? between models. I would appreciate any input
Sorry to learn of your bad dose of COVID-19. Glad of your recovery. Welcome back.
My speculation that additional chassis holes and upper panel holes may be for:
- relocated tone control from the left rear corner of receiver, drilling the chassis apron front.
- relocated power switch, usually mounted on the cabinet right side .
- radio/phono switch (for radio reception, the rear phono post must be jumpered to the adjoining ground post. For phono operation, the phono pick up is wired between the phono posts. The Scott supplied phono had a radio/phono switch to change back and forth to bypass the phono wires. But other phonos may have had no such switch and perhaps one was rigged on yours and mounted on your panel or dine inside requiring another hole drilled in the front chassis apron.
Perhaps your Scott was returned to the factory for repair, but usually signified by brown paper tape on the from electrolytic.
Let us know how your detective work turns out.
did the allwave 12 have any type of bandwidth control?
No band width control for your 12 tube Deluxe nor the Allwave Fifteen. The AW-12 is 1932-33 technology.
Bandwidth control came about in 1935 with the 23 tube high fidelity model to take advantage of the experimental wide band Hi-Fidelity broadcasts starting about 1935, initially in major cities like NYC, Los Angles, Chicago and, I recall, St Louis. These broadcasts were at the top of the dial above 1500 KC. No FM until 1940.
FYI - Scott accomplished band width control width with a secondary shaft across the back of the receiver below the IF Transformers that operated small alternating air caps to de-tune the IF peaks. This was not something to try retrofitting an earlier model.
The serial number puts it firmly in early 1933. I'm with Dave on the extra controls: the only way to figure it out will be to open the set up and trace the extra controls and sketch them into a schematic. The functions should become clear...Scott sets got updates from owners all the time. I recently found an AW23 that someone tried to semi-permanently attach an expander to - drilled the set to add the expander control on the chassis and moved things around.
