March/April 2013

ONE OF MY RESTORATION EXPERIENCES Kenneth E. Hodge - CRC Member One Sunday afternoon in 2006 my daughter alerted me to a radio at a garage sale in our development. I hustled over there and found a Philco Model 40-105 batterypowered farm radio tagged at $20. The floor-model case was in fine shape; a quick look showed no missing tubes or knobs but the speaker was missing, or so I thought. (I later learned the speaker was enclosed in a thin wooden “Tone Chamber.”) I told the owner that, because “the speaker was missing,” I’d give him $15, which he accepted. He explained that they had kept the radio for ages as an icon in silent memory of a long-departed grandmother and felt it was time to move it along.

rado or nearby Wichita. I returned the checks to the man who sold the radio to me, but not until I had opened the Tone Chamber to be sure it wasn’t full of cash or other items of interest. I replaced three of the four 1.5 volt tubes which were weak or shorted, that left one Philco brand tube in the line-up. The chassis was clean and the only component showing visible distress was a 20 mfd/200 volt Mercury-brand electrolytic capacitor across the B+ that I replaced. I restrung the simple slide-rule type dial pointer cord and gave a shot of cleaner to the volume control and power switch. I then powered up the radio using my Antique Electronics Supply ac/dc power supply and the radio played like a champ. I used an odd length of wire for antenna (no loop or ferrite devices in this model).

Full Disclosure: My father was a Philco dealer and I have a showroom photo from 1940 that shows a Model 40-105 set in his line-up of radios for sale. Back in my workshop some days later, I pulled the chassis to check the tubes and underside wiring and several old cancelled

checks fell out. They had been tucked behind the tubes and had been written in 1940 by the late grandmother to a grocery store in El Dorado, KS. So I suspect the radio may have been purchased in El Do-

Now I wanted a small power supply in the radio so I could demonstrate its operation. In my non-electronics junque boxxe was a clear plastic box about 4 x 5 x 2 inches. In it I installed two 1.5 v. D cells in parallel and ten 9 v. batteries in series for 90 v. to comprise a battery power pack for the radio (see photo of installation in Philco 40(Continued on page 3)

Message from the President Hi Fellow Club Members ; I’ll make this “Short and Sweet” and to the point. Our annual show will be March 24th. As usual at the Ramada Plaza Convention Center. I-25 and 120th Ave. Elsewhere in this edition of the Flash you will find all the details. Some of those are: There will be a special “Purple Rosette” award for the entry that is judged the Best Educational Display. We do not have an official “show coordinator” this year… but some of us will be there early to assist in the placement of radios and misc. related show entries. We will group those radios, etc. that are “not entered to be judged” grouped together. This years special category will be : radios that have a tuning eye tube or some other means of indicating correct station tuning. Other examples PAGE 2

could be an “S” meter, or a moving shadow meter like in 1930’s Philco radios. You get the concept! Please wear your club badge; that is your entry to the VVE Expo and the vendors inside… for both you and your significant other. We anticipate that Denver Channel 6, PBS will be there filming our show for another story for their online Vintage Colorado series, let’s make this the best turn-out ever…lots of radios and displays! We will discuss last minute details at the March 13th club meeting to be held at the Phillip Miller Library in Castle Rock.

What’s happening at the CRC? At the January meeting there were several proposals regarding adding categories, awards and identification of radios eligible for the best restoration award.

gested that we add a separate table to display non judged items. All members are encouraged to bring entries that don't fit into the other categories or ones which they don't wish to have judged (for any reason). This is a great place to enter items which have previously won awards but you want to display them again. By doing this, you give others a shot at winning one of the coveted awards given by the club.

Dave Boyle suggested that another category be added. He proposed that we add Best Educational Display. This would be judged by the members of the club and the general public. It would be given for the display that is the best at providing information about some facet of radio. A new rosette ribbon would be awarded for this item.

Additionally, Larry Weide noted that there will be a mark on the identification hang tag that will indicate that a radio has been restored. Only these radios will be eligible for the “Best Restoration” award.

In addition, it was also sug-

Riders "Hidden" Supplemental Information by Larry Weide, CRC Member The following is a re-print of a previous Flash article dealing with hard to find yet readily available technical information. It turns out that throughout the Rider series of the "Perpetual Trouble Shooter's Manual", known to most of us as simply "Rider's", there are inserts of data that concern various techniques and components that were widely used by particular manufacturers. The problem is that there's no index nor particular logic for the location of this data. Unless you just happen to run across an item you may not know it's there. For example, some time ago I acquired a Philco Model 112 console. When I was perusing through its diagram on page 466-4 of Rider's volume II (by-the-way, Philco at this time is still known as the Philadelphia Storage Battery Co. in Rider's), lo and behold, I discovered a very complete description of Philco capacitor and resistor potted bakelite modules on the very next page! A stroke of luck since there's no reference to them anywhere in the manual. So, with a lot of scanning through a bunch of volumes, I've compiled a “list of lists” that I hope will be helpful. You'll notice that data is limited to only a few manufacturers. Presumably this is because they're the only ones that presented this kind of data to be published, but then they also represent a goodly portion of the radios produced during these periods. Also, I limited my search to Rider reference volumes since these manuals are already in the hands of many us and available on the internet at www.nostalgiaair.org. I might also mention that the first two volumes of my particular set of Rider's were published for the National Schools. Therefore, there likely will be discrepancies in page numbers between your volumes I and II and mine.
