I obtained this interesting Emerson 868 "miracle wand" transistor radio from someone on ARF. It's a 4 transistor radio built on a metal hand wired chassis using plug in transistors. It runs off of a large older style 9 V battery that's expensive today. I'll probably modify it to run on a couple of modern 9V batteries wired in parallel for more current. I see where someone has already added a regular 9V battery holder to the chassis. As you can see, this radio uses old style multi-section electrolytic caps and there's even a paper cap visible. The radio plays; but, is very weak which is probably due to bad caps. I will try to wire modern caps out of sight under the chassis and leave the old multi-section units in place for appearance purposes.
I'm really not expecting much performance with just 4 transistors; but, I think it's still an interesting radio.
