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!
