Allwave 12 Deluxe with Nelson Cabinet

[Charles Tedrick]

1. Here is my Scott that I recently bought at a local auction. I met Dave Poland at the auction and he suggested that I sign up here. Apparently the cabinet is unusual or rare so I should post plenty of pictures for everyone to see

Hey Charles - welcome. Good decision. We met at the auction.

An AW-12 Alwave Deluxe is a good model as your first Scott  restoration. 

There is help here. You can try a search for AW-12 and the similar AW-15 for threads with photos and hints. This chassis has good access inside to most caps that need replacement. In addition to the obvious ones underneath, there is one inside  each IF transformer can - the middle 3 across the back of the receiver. Those large chrome cans are press fit and cover a number of coils and such.

Regarding the coil wheel inside, you will need to dismount it to access a couple caps. CAUTION move the band switch to full counter-clockwise (broadcast band) before you dismount the coil wheel and do not turn that pointer knob until you have re-mounted the coil wheel. WHY ? because that assembly also has a shaft into the overhead antenna coil that operates a switch, there which can be broken if the coil wheel drive is disturbed.

But first, print off the an owners manual for an Allwave Deluxe with AVC (Automatic Volume Control) to get familiar with features and the control functions. You will also find technical info and circuit diagram for the model using a blue glass Wunderlich tube (3rd back on the left side).

Hello Dave
If I decide to try and take on a restoration, this is definitely the place to go.
I love collecting old fans, radios and lamps. I have never even tried to restore a radio before. It may be something I would enjoy if I tried.
I tried posting pictures here but I'm not having any luck.

Charles - Your 12 tube Scott has a lot in common with a basic 5 tube table radio - except more tubes, enhanced engineering and superior design. I had no technical background 30 years ago but did some reading and asked questions. You have a wider array of resources than I did.

Your 12 tube Scott design:  adds a radio frequency amplifier tube ahead of the first detector (aka -mixer or converter), 3 IF amp tubes instead on just one, a separate oscillator tube, 4 tubes of audio application instead of just one. Plus you Scott has 3 short wave bands, handled by the several coil pairs on the big elegant coil wheel inside turned by the pointer knob.  Your Scott is uncrowded inside giving good access.

But before attempting any work on your Scott, review  some topics at Phils Old Radios: https://antiqueradio.org/recap.htm

Start with his topics on Capacitors. And note any soldering technique.

Then, maybe try a couple restorations on larger size 5 or 6 tube radios of the mid or late 1930's - like Zenith or Silvertone.

Avoid the small 5 tube radios because the parts are usually crammed into a small chassis complicating restoration work. Avoid AC/DC radios because of safety concerns. Better a model with a power transformer. The larger 6 to 8 inch speakers sound better. Philco radios are good but not for a beginner - having complications as bakelite bock caps and, in the later 1930's, sub assemblies.
