I wanted to share a recent completed restoration with those interested. E.H. Scott Laboratories created and built some of the finest receivers/radio sets money could by during the entire span of the 1930's and early 1940's. Of all the circuits I have ever been into (pre-war) E.H. Scott is by far the finest. The combination of full shielding, perfected circuitry detailing excellent sensitivity, selectivity, and fidelity performance make an E.H. Scott product such as this 1932 Allwave 12 Deluxe a great performer. Not to mention the beautiful chrome too!

This circa 1932 Allwave 12 Deluxe was ahead of the competition upon introduction to the market. Shortwave listening started to gain popularity in the early 1930's. Very few general public sets, if any, offered full coverage utilizing four bands. The Allwave 12 Deluxe did. The use of an internal movable coil system was a first too. Many manufactures were still utilizing plug in coils during this time. E.H. Scott set the standard for the market every year. The Allwave 12 is no exception!

The Allwave 12 presented below had not been serviced for decades. The original speaker set was missing. A rare (correct) E.H. Scott combination Rola speaker system, which was offered during the 1932 year, was added to the set to make it complete. I ran into a shorted filament winding on the HV secondary. A replacement power transformer was install off an E.H. Scott two dial AW-12 power supply. Only difference between both Deluxe and non Deluxe power transformer is a chrome strip that covers the power transformer laminations. A fresh set of electrolytic's, non polar caps, tubes checked, and resistors tested (Tolerances within 15%!) and she fired right up. Dial calibration and alignment had been check, still spot on after all these years. The entire set was carefully disassembled, including cabinet for cleaning. This is a 100% original wood finish cabinet, very well preserved cabinet. I think the results speak for themselves! Not the most attractive E.H. Scott console out there, this early Tasman was the beginning of a series E.H. Scott continued to update until the late 1930's-early 1940's.

Comments welcome, no video this time! This set performs phenomenally!

Jon

Very nice restoration. That's a real keeper. I'm glad to see you went the extra step in cleaning up the chassis. With a Scott, I think that's just as important as cleaning and polishing the cabinet. It looks like you've done everything I've done in restoring my Scotts except my Philharmonic in which I also replaced all of the carbon resistors with NTE 1W metal film resistors. I don't know if you dissembled the tuning mechanism, cleaned it, and put it back together. That's what I always do. Enjoy your Scott.

Great job! Definitely a keeper. I have the later AW12 w/AVC and single Jensen. Hard to beat the performance.

Great work Jon !! I also have a similar early AW12 single dial with the twin rola speakers but mine has no tone control (also aka static control) on the rear right corner like yours. Surprisingly the tone is to my ears perfect and does not need any tone control.

You did a wonderful detailed restoration-that chrome really pops too !! Does that antenna tuner do any fine tuning on BC or just work on SW?

Excellent work, Jon!

It's very fine looking, topside, bottom side, inside, and out!

NICE JOB !

The only other multi-band shortwave "consumer brand" radios at that time were offered by Midwest and Silver-Marshall as far as I know. I have one of the Silver Marshall Model 725 I think, its chassis type Q, made just as they were going out of biz. We had some discussion of them a few years ago here on the ARF. Then they came back as McMurdo-Silver in 1934 I think.

Thank you all for the comments! This AW12 is quite the performer on the shortwave bands. Bruce, I am utilizing the antenna tuner on the shortwave bands. Performance of the tuner is quite good! Mark, appreciate the information on other general consumer sets featuring all wave tuning in 1932!

Jon

Thank you both! sprman, I was able to utilize a 25 ft. insulated braded copper wire indoors to obtain reception. Shortwave reception utilizing this 25 ft. antenna was phenomenal! I could only imagine the performance attained using a proper antenna as described within the original instruction manual. These E.H. Scott sets are truly fine performers compared to most other time period sets that were available!

What an incredible radio and magnificent restoration. I would like to see how the tuning coils are selected, anybody have a video ?
One of the coil forms doesn't show any turn of wire, the one on the right, or maybe I just can't see any wire ?

Thank you for your comments. The entire coil system turns on a series of beveled gears. There are four positions. As you turn to each band, the wheel moves in a circular motion. There are two separate sets of contact points (West/East positions with respect to position of chassis shown in picture) below the entire coil system that make contact with two coils (depending on band selected) at all times. The coil form with no wire is correct. Shown in the picture you attached is the broadcast band selection.

Holy Christmas, reminds me of the old aircraft rotary engines (Gnome 1918).

You are indeed the right new owner for this AW-12 and cabinet.
