1934 Doerle Twinplex Shortwave Receiver 

In either the 1934 or 1935 Official short wave radio manual there is an AC version called the 53 twinplex. Uses a type 53 twin triode.

Beautiful build! I'm gathering parts to build a 'Signal Grabber". Doerle's Forever! 73, bill.

Very cool vintage.

while back i bought this old radio in hopes of restoring it but was not successful - should have find our channel as you seems to knw a lot about it!

That’s very interesting thanks for sharing

The book mentioned at 13:39 is Secrets of Homebuilt Regenerative Receivers, by C F Rockey

I was watching buzz1151, and thought to myself, I have not seen batterymaker in a long time.

The potentiometer just need cleaning. Use tuner cleaner. Even wire wound controls need cleaning 73

How long will the batteries last?
