Detrola 4-D TRF Needs Some Attention 🙂

This is a Detrola 4-D TRF AM Radio vintage 1932.
I will be working to restore it electronically and when the weather warms I will work on the case.

Those capacitors look OLD, great radio there. 😃👍

Oopsies. Model 4-D (not D4 as you typed it in the description). Some versions of this radio had a couple of gimmick caps in it. There are actually 4 versions known of this radio but only two documented schematics. Tuning capacitors were a big problem with this model. They need to be cleaned carefully or they short out. The volume control may be too high in resistance for the upper broadcast band so you only get a few strong stations. Many of the old style resistors tended to go too high and radios developed oscillations. TRF sets were on their way out about that time ( 1934) for all it's worth.

LOL, I'll correct that. Well, I've noticed there are only 2 schematics and there are differences between them as well as my radio.
