Anybody know what the heck this thing is? I've got an old electric organ where one of these things is busted so it won't make sound anymore. Don't know what it is
Pictures of the working one
They are variable inductors tbh
Says right on top of them
20-40µH
5-10µH
Could be a capacitor. Just a guess. You could Google that maybe.
some kind of adjustable inductor.
more info needed on make of organ.
It's a Baldwin interlude
I thought it looked like a capacitor, but I couldn't find any information when I googled the numbers on it
so it appears those cans are used to tune notes, and maybe other stuff.

yours looks like it is turned to far out, but I cannot be sure.
I googled "Baldwin interlude" parts
Variable inductor (coil) 5-10uH (micro Henry).
prob this,
to op if the device worked fine before DO NOT turn it with a screwdriver,
unless you have a handbook how to tune the device back in.
>to op if the device worked fine before DO NOT turn it with a screwdriver,
When I was a kid I had a transistor radio that worked ok, so one day I turned one of those a bit and the station got louder. So I played with all of them until that station was as loud and clear as I could get it.
I was surprised when it never picked up any other stations after that.
ah yes the ol' "golden screwdriver".
IF Transformer (IF = Intermediate Frequency)
a adjustable inductor
it has basically a screw inside that is made of brittle ferrite including the screw threads so
only tune with non conductive tool (plastic) or you risk damaging the ferrite core as well as cannot tune precisely ( if using ferromagnetic tool )
Looks more like 20-40 to me but it's hard to decipher
>Looks more like 20-40 to me but it's hard to decipher
I think your're correct. I looked at the non-broken part.
>one of these things is busted
what makes you think its broke?
why did bendy traces fall out of fashion?
bendy traces were done by hand
modern traces are done by human-guided autorouting
Also high speed digital electronics require precise routing & even matched length for parallel traces, and you ain't going to get that with a guy and his pencil.
Early PCBs were drawn by hand because CAD either didn't exist yet or was computationally so expensive that it was cheaper to get some guy do it by hand.
Modern Traces in high-frequency electronics need "impedance matching" because electrons travel at (or close to) the speed of light and the higher the frequency the more the exact timing becomes an issue.
Gotta correct myself, impedance matching is the wrong term, the gist still stands though.
High-frequency is to normal electronics what quantum mechanics is to classical mechanics. Basically throw all the laws you learned out of the window. This is bat land.
This goes as far as electrons travelling differently around sharp turns than around smooth turns and shit like that. It's a total clusterfrick.
good thing you corrected yourself, for about seven minutes there everyone itt thought you were a dumbass
Here's one more moron question:
Why are the traces green/masked but the rest of the pcb not?
Oh wait i see, it seems to be used as a guide for seeing how the traces on the other side are laid out.
