Interesting (wacky!) Tube/Valve receiver

March 9, 2011 | Amateur Radio | By: Mark VandeWettering

Here’s an interesting project: a tube based regenerative receiver that uses an LM386 as an audio amplifier. Wacky. Still, it appears to only use 12v supplies, which may make it a fun and interesting project.

Addendum: Apparently this YouTube video served as inspiration. Cool.

Neat! I wonder if a triode-connected 12DZ6 would work any better than the 12AU7, given that the 12DZ6 was designed to work at a 12V plate voltage. May have to try this some day. Nice find!
