I purchased a VHS tape years ago that showed the assembly of an AW-15 filmed in the Scott factory. Nice shots inside the factory. if this isn't already available on the website i can try to get it digitized and share it

Hey all...I have two Philharmonic sets taking up space and I won't be finding time to do anything with them...so I am putting them out here. The first is a red band deluxe (1939). This set has caps replaced and does play but needs additional work. The second is a 1937 pointer dial set with the "Chicago" dial. This set is unrestored but complete. Both sets include a tuner, amp and a 15 in speaker.…

I'm working on a 1939 Beam of Light Philharmonic Deluxe and noticed a wiring error (ok, maybe)...in looking at the schematics available, it gets worse. Refer to the 3 images attached as needed. Here we go:

In the 1937 schematic, and in most sets I've worked on, pin 8 (cathode) and pin 5 (grid #3, usually tied to the cathode) go directly to ground. Pin 5 (at ground) is used as a tie point for the "pass through" caps in the IF cans. In the 1939 schematic, it looks like Scott added a…

Next Wed evening (10/16), I will be presenting on E. H. Scott and his radios on the AWA Shares monthly Zoom meeting:

You do not have to be a member of AWA to attend, but you do need to register prior to the talk. I hope some of you are able to join me - I've got some neat pictures and info to share.

This is the beginning of a running blog on updates to the files saved in the Info Archive. This morning, I updated the file "Milsets.pdf" in the WWII Sets folder. Fellow member Angelo found some new US Govt documentation on the WWII sets and I have updated the file with a few new bits of info. More to come soon.

I met a fellow at Kutztown who has this set. He says he has the PS and speaker as well. It is in NJ, email me (kent3256@hotmail.com) for more info. There is an expander with it...…

Does anyone know where to find replacement grill cloth with this pattern?   IMG_4132.jpg

A collector has reached out to me seeking parts for an RC6 phono - if anyone has one that is good for parts, please drop me a note. Thanks!!

Tubes all light and warm. Nothing on AM or 3.7 carrier, 7.25 carrier and 18.26 carrier broadcast from nearby antenna. Zilch. General advice is to replace all tubes or one at a time. What do you say, group. Hum low to moderate so speakers and audio working.

I have a pretty decent pointer dial Philharmonic, with the midwest station dial (new replacement, original was cracked). The set is complete and chrome is very decent, this set will turn out great with a good cleaning and restoration. Includes a full set of tubes (the smaller 6L6 tubes are GA, not G, couldn't find 4 matching ones). Amp has some rust but is also cleanable. And we have a good 15 in pedestal speaker with it.

I will not ship this, but will meet you or deliver…

I've been working on several Philly sets and I am really just appreciating all the differences in the various sets. So the earliest ones had a series of 5 capacitors which are switched across the plates of the P-P expander tubes. This feature was changed to a treble control and also removed if you had a remote control chassis. I need to know what the rotating switch looked like for the assembly shown here:…

I found this reference in a 1928 sales booklet. I would like to find the piece described. Next best - a good scan of one if you have it:

Scott Radio Friends,

I need some help. I am finishing a restoration of a Scott Warrington cabinet. Everything is place except one thing.

I need a working on/off ac toggle switch.

Here's the catch. While the exit bore hole is .5 inches in width... the depth is also just over .5 inches wide. It is .75" thick wood...

The larger initial hole is 1.5 inches and @.2 deep. This means I need switch with a stem around .75 inches to make sure the toggle clears through the hole…

The title says it all...does anyone recognize this as a McMurdo Silver cabinet? I'm guessing it is not, obviously the mounting is all wrong. Opinions?…

To members: I came across this February 1935 issue of Broadcast News online. It has a fascinating discussion on High Fidelity broadcasting, which was in its infancy, and the challenges at hand. The story has a relevance to  E.H. Scott Radio Laboratories because Murray Clay came from RCA as and electrical engineer in their radio licensing division just before this article was written.  As many of you know Clay was instrumental in helping Scott develop their High Fidelity receivers based on…

OK folks...question: Here is the schematic of the outboard volume expander for an AW23. I was working on one earlier today and noticed a mod that I had not seen before. If this mod isn't factory, it was done a <long> time ago - near its original production. The mod is simple - a 20ufd/25VDC cap is wired from the 6A7 cathodes to ground (+ side on the cathode). It is soldered right on the wiper of the balance potentiometer. Any thoughts on what this might do? Should I remove it/leave it…

The pot metal cast parts that support tuning capacitors are cracked in my unit.  I wonder what can be done to fix it.  Has anyone tried 3-D printing or is there another way?  Thanks, Jiri

The shippers and everyone did a fantastic job getting the Valencia set from the LA auction to my place here in Ohio. I have wanted this cabinet for many years, I'm so excited to finally have one. This is one of my winter projects, the set is really clean too, I expect this one to be a showpiece set when restored. - Kent…

If anyone can look at the underside of a red-band Philharmonic Deluxe, I need to know where the switches and the variable capacitors should be at each end of the rotation. After recapping, I realized this set has been played with and I do not believe the shaft is properly aligned with the control. Any assistance would be appreciated!

BTW - this is not the same as a pointer dial set - the Deluxe has an extra wafer switch on the shaft - so hopefully someone has another Deluxe…
