The Philco 38-62

After
One of the most difficult things in restoring a Philco radio like this is dealing with the paper veneer. As you can see in the above photo, the paper veneer was pealing away from it and is showing what appears to be the pine wood under the veneer. If you try to strip this radio you would find that what appears to be an impressive wood veneer of different types of wood on the front, is really just a cheap paper veneer. After anyone strips a cabinet like this you end up with just plain pine front. So, I voted not to strip this cabinet but to darken the areas of missing veneer with a dark stain so that it would not stand out as much. The results were okay, but I think it was better than just losing all the paper veneer all together.

The above photo shows the chassis removed from the cabinet after the radio was restored and operating. When I got the radio the dial was still in good shape, but the power cord was cut and two tubes were bad. This radio uses 5 tubes which are: 5Y4G, 6A8G, 6K7G, 6F6G and 6Q7G which seem to be a rather common tube line up for that time. Of the five tubes, the 5Y4G and the 6Q7G tested bad on my TV-7B/U. Replacing the 5Y4G was no big deal, however, the 6Q7G was a different story.

We have all heard that a 6Q7GT = 6Q7 = 6Q7G tube and interchanging them is no big deal, and in most cases this is true. However, if you look at the above photo you will see a 6Q7G tube in the socket of the Philco 38-62. The small metal case that surrounds the tube socket is used to hold the metal tube shield that is needed to shield the 6Q7G tube. The tube shield is somewhat square and fits around this small metal case to make a good ground. Notice how the tube base is just small enough to fit inside to make contact to the socket!

Notice the two above photos where I tried to place a 6Q7GT tube and a 6Q7 metal tube in the socket. Keep in mind that the socket is level with the chassis and not level with the top of the small metal case that surrounds the socket. You can see from the photos how both tubes are just resting on top and not making contact with the socket and thus, will not work.
Bakelite Block Condenser This is the famous Philco Bakelite Block Condenser. As a Philco design, these you will not see on any other radio. They seem to come in hundreds of configurations and in a few different sizes. They have capacitors in them from 0.01 Mfd. to 0.18 Mfd. Some with one capacitor, some others with two and a few with resistors too. The problem is that they too need to be "recaped". There are some books for collectors on what should be in each of them. Once you have determined what should go into it, you then need to remove the caps from what seems to be a tar like substance. Using a heat gun, you can melt this tar substance and remove the old caps and resistors. I then use paint thinner to clean it out and then solder in the new components. It's sounds much harder than it really is.
This is a photo of the radio just after I got it.
