Hello, I'm watching from Sao Paulo, Brazil. Do you know a good AM tube radio Kit to recommend ?

I like the transistor radio.trick,hopefully It I ever need it will work for me ,I bought a little radio I.keep next to my work area.either way Learn something new thanks.

Had a fisher 500s with an open oscillator secondary transformer, removed silver mica, replaced with mica caps ,had to “unwind secondary about 20 feet to find the open winding resoldered had my oscillator! Albeit a bit off freq

Fantastic, I learned a new trick with this video to tell how the oscillator is working. Thank you for posting this video. :)

I like the way how you show the schematic diagram in conjunction with the radio and the corresponding components you are describing and testing. I have learnt a lot how to find out if the local oscillator works and how to test with a simple portable radio as a "help" to find it. Thank you very much for this wonderful tutorial and practical lesson.

Nice work bud . if i find a connection that i can touch and find a mains hum would it be ok to insert a normal line feed from a line out source ?

small transistor radios are also a good way to test car remotes...held close to the antenna they. make static if emitting something.

Interesting vid...I've been restoring radios for a long time, and I've never had an open resistor that didn't look damaged. I guess it just goes to show that anything is possible! This video also points out something else useful; for basic radio troubleshooting, no fancy test equipment is necessary, just a simple multimeter works fine.

yup 8.2k was open most common thing in those old tube sets. i used to work on many sets in the 70s up 80s up .did tv repair ham sets cb amps. wide range learned a lot had much fun.

Thanks Jan Scheltes I have an isolation transformer. On the isolated side of the transformer I have a VARIAC. I have used light bulbs before and they were quite well. But today I always use an isolation transformer and a VARIAC.

This radio is AM only. However the interference would also work if you put two FM radios close together.

The best that I can tell, is that it looks military, and from the label looks like it was a tube set. From the video it looks like it still has one tube and it has been transistorized. That's about all that I can say about it without drawing up the wiring diagram. And since it is a custom modification to learn more about this unit you would need to draw up the wiring diagram.
