The first Allwave 12 Deluxe

[Kent King]

When Scott first introduced the new Allwave Deluxe set, it really wasn't much different than the 1931 2-dial set with the newly developed rotating coil assembly. The tube lineup includes four 24A tubes (1st det and three IF tubes), four 56 tubes (osc, 2nd det and two AF stages) and a 51 (RF), plus the amplifier. The set does not have AVC: front panel controls are just a 3-position sensitivity control and a volume control that varies the IF bais. These sets were produced in the summer and fall of 1932, by December, the Allwave Deluxe with AVC (using a Wunderlich 2nd det) was being sold.

The non-AVC 12 is fairly rare, having only been produced for a few months. I have one in my collection and have only seen a very few others. I finally began restoring mine after the holiday. The first challenge was a schematic - there is not one published in any Scott literature. There is a schematic in the November 1932 Radio Craft magazine (with an article written by Scott). However, this diagram doesn't show a power supply and doesn't entirely match my non-AVC set (serial #A-229). So I set about drawing a diagram for my set and amp. These are attached, I'll upload some pics of the set soon.

Does anyone else have a non-AVC Allwave Deluxe?

And yes, this is the set that prompted my earlier question about the dual speaker system.

I'm wondering if the voltages on my receiver would be different than the voltages on "Instructions For Checking And Aligning The Scott 12-Tube Deluxe Allwave Radio Receiver" printout.  AW12D Alignment.pdf

In reading the instructions, they talk about the first detector as being a type 57 tube.  Mine is the very early Deluxe with 56 tubes for the second detector, oscillator and 2 audio stages.  24s for the 3 IFs and a 24 for the 1st detector and a 51 for the RF.  I would think with the difference in tubes that the voltages would also be different.  Any Ideas on this matter?

Thanks Dick

  I just wanted to say that I have my Allwave 12 Deluxe playing very nicely.  Listened to the whole Cleveland Guardians game today without any problems.  Lots of volume and hardly any adjustment in the alignment.  Plays beautifully.  Now I just have to finish the cabinet.  I'll show some pictures then.

Great news! Scott sets sound and perform wonderfully once they are restored. I look forward to seeing some pictures of your set!

I recently found this set close to home, an early Allwave Deluxe with serial number B-100. I sent the number to Kent, it is one he did not have so he has added this to his records. This set has an 8 pin plug and the rear of the chassis was not punched for a tone control and it has the small serial number plate. It was very dirty but came with a plywood front that had 2 escutcheons, the wave band switch and one ship wheel knob. I stripped the chassis down and cleaned everything, and made a new front with some wood that I salvaged from an old cabinet. I made it 12" wide but have looked at photos of other sets and think this is a bit too wide, maybe should be closer to 11" wide. Does anyone have a set with the original panel and could confirm the width prior to trimming? I am planning to do an electronic restoration of this set for a winter project using the schematic which Kent King provided based on the November 1932 Radio Craft article posted earlier in this thread. The chrome on this set is only fair, some of it was scuffed up during previous cleaning attempts but it looks much better after cleaning and polishing.

Scott shipped receivers with a wood panel in place with escutcheons mounted well into the late 1930's. If a cabinet was purchased, then the owner would move the escutcheons to the cabinet when it arrived (shipped separately from the furniture factory). Some of the shipping panels were saved, and turn up now. I had one still loose in the cabinet. Or the wood panel could be used to retrofit an older cabinet. If you had an older Scott cabinet, the buyer could arrange for a new panel to match the size and veneer of the older Scott cabinet. Some receivers were evidently never mounted in a cabinet.
