I have a bit of a dilemma. The RF amp tube (a 6U7G) in my Philco 38-3XX console sits in a rather odd-looking socket base. THe socket itself is nothing out of the ordinary, but there is a piece riveted to the chassis that looks like a sort of short cylinder with two sides flattened out, and a hole in the top for the tube to go into. I presume that a shield is supposed to go over this cylinder, but it is the only thing of this type in the radio, and a standard round Philco tube shield is too big, and a Philco square shield is the wrong shape. Is a shield supposed to fit over this? It's at the lower left of the tuning condenser in this photo:

If a shield IS supposed to fit over this, would someone PLEASE post a photo so I can send it to Mark Oppat at Old Radio Parts and get the RIGHT one? BOTH of us are getting a bit bewildered by this thing...

That looks like it needs the cylindrical aluminum shield used in Philcos with the 6U7G RF amp.

you could use a round one but on mine it has a square one [just like the others] that sits at an angle to all the rest because the cap wire will not connect if it was turned like the others if it did it would short out david

Mondial is correct - that base was meant for the cylindrical aluminum shield as shown in his photo. I do not know why Philco used this odd shield in certain 1938 models instead of the typical square shields Philco used during that time period.

Thanks, all - that's a BIG help!

In some Philcos, the use of this tube shield base also prevents the use of GT style tubes that have a slightly larger base than the G tubes do.

The photos were a HUGE help. I now have the correct tube shield. Thanks all!
