Homemade Tube FM Tuner: Amazing Audio From The Junk Box!

Having built a couple of superhet radios I've now made this pulse-counting FM radio. It's really easy to make with no complicated alignment to do and sounds surprisingly good for a few junk box valves!!

I don't know why, but tube (valve in the UK) radios just have that sweet warm sound to them. A lot less harshness than we hear with solid state radios. Great work putting this one together!

Hello from Cool386, and great to see your version of the set. Looks like it's performing as it should, and well done with your excellent construction technique - so important for VHF.

Awesome 🤩🤩 Thanks 👍👍

Thank you, very enjoyable. In about 1980 I made a successful pulse counting valve receiver for the 2m FM band. I think I used an IF of about 50 kHz. Also, Sinclair made a pocket FM radio using a pulse counting circuit.

[@ingussilins6330]

I use solid state pulse counting FM radio for NFM 421-424 MHz band.

Are there any fm transmitters? I'm very happy with learning tube transmitters

[@wrsdes]

Could I have the details please

[@slender1357]

Do you think i can replace the 6au6's with ef80's?

[@thewtf]

Yes I reckon ef80’s would work

[@cool386vintagetechnology6]

They do indeed work very well.

[@jakep8484]

Sounds like its an AM radio, cool project though
