Wow ! Me likey !

Thanks, guys. Next one I do, maybe just a tiny bit bigger, and a real MK-484 chip etc. inside to be a real radio. Good way to use scraps of veneer.

That's really cool. If it were slightly bigger, battery powered, it would fool a lot of people into thinking it's a real tube radio. To go over the top, one could install some fake (dead real) tubes.

I'm still impressed by the small size. And nice veneer work, it's not as easy as some people think....

or you could get away with a real one using subminis and nuvistors?

Very awesome work!

Wow! Seeing it next to the 50C5 is impressive.

Very nice
Is an MK-484 a single chip AM radio ?

[Reece]

¡Gracias, todos! Yes, the MK-484 is a single chip TRF radio. It has several RF stages, AVC, and detector all enclosed in a case no bigger than a transistor. Just a handful of other passive components and you've got a radio that works with earphones. It likes to work at a little less than 1.5 volts. Add a couple of transistors or an amp chip like an LM-386 and you can work a small speaker. I made a pocket radio with an MK-484 last year:
