Hey all,
Went to a yard sale yesterday, picked up a cool steel case for a footpedal. Bought it for a $1.00.
It turned out to be this cool numistor cascode with the smallest tubes I've ever seen.
I was going to put a footpedal in there. But now I don't know. Is there something else or just go ahead with plans.
I couldn't go wrong with a whole chassis for a buck. So, either .... Well, that's why I'm asking

Nuvistors are nifty little things, there's a single triode (or pentode) in each one. They tend to be very low noise, high-gm devices.

but what do you do with them?

I mean, can you build a nice guitar amp out of them or who knows...

Not much you can do with it really. It's kind of a nifty novelty, but if you need the chassis and transformer for a project, I wouldn't be afraid to gut it.

What Nuvistors does it use? The only Nuvistor I've ever seen in an audio circuit was the 6CW4, which was popular in the 1980s for home made phono preamps and moving-coil pre-preamps.

I suppose Nuvistors could be utilized in some sort of tube-type overdrive pedal, but I have no idea what sort of circuit one would use for that.

Those are the tubes it's using. I guess I'll just put them to the side, maybe something will come along that they can be used for.
Again for a buck, nice metal case. Some kind of something can go in there

So the box is 6CW4s in cascode? Like an antenna booster for FM radio?

If you ditch the tuning capacitor, and make sure that the coupling caps are big enough to pass audio frequencies, that might make a fun overdrive circuit, although the gain may be a bit over the top for an overdrive.

Or you could gut the chassis and use it for whatever you originally intended, and just keep the 6CW4s and their sockets (ESPECIALLY their sockets...) in a drawer for some unknown future application, or move them on eBait.

Yes, it's an FM preamp or booster.
What your suggesting sound's fun. So if I ditch the tuning cap replace it with
