38-690 Missing amp and 14" woofer
#3

Hi Peteivan

Yes, the efforts would be worth your while, especially since you only have $25 invested in it. Congratulations!

You could possibly adapt a jukebox amp, but you'll also have to be able to supply needed voltages to the upper (tuner) chassis. The original used two 6L6G output tubes.

Bruce mentioned a 38-116 woofer as a replacement. One of these would be much easier to find than a 38-690 woofer, and yes, they are the same size. However, the 38-690's amp wants to see a woofer field of 4000 ohms. The 38-116 woofer's field coil only has a DC resistance of ~350 ohms. There are ways to get around that, of course.

As for the tweeters. If they are there...it is a great thing...and if they did not make much sound, it is because of a factory wiring error that had the tweeters wired out of phase, cancelling out their sound. Details, with a fix, here:
