Appears the left side is for an external resistor (bleeder). Although a little before my time, television and radio used very large filters in their power supplies. Thumbs up for the interesting topic.
Nice stuff! Being an amp builder, I would appreciate one. BTW I love these threased base can electrolytics. They're often still good, only in need of reforming; I reuse vintage caps if they test good on capacitance, ESR and leakage current.
Maybe consider building one yourself some day when you have the time. Not trying to be snarky, just encouraging. I realize this could come off as passive aggressive. But I think it would be a fun little project. Even if a little tedious to construct.
Ready made project box with a toggle and 8-pos rotary switch and some binding posts... Not sure what I'd use it for, maybe a switchable LF filter or generator or something... Assuming I ever had the need for that!
Just for grins, test for value and breakdown voltage of all of those caps. I have an old NRI magic eye RC bridge that tells me that. From working on vintage radios, just about every electrolytic was down to 10% of its original value and breakdown voltage was as low as 50 volts.
Gut the box and build a tube regen radio with the same face plate. Same with the resistor box. Sometimes nostalgia gets the better of you, but let it go.....
is it wired using surplus phone wire?? you know you’ve got a good one when it’s wired with phone wire. i remember back in the day you could find tons of it in the trash in office buildings.
it's magic! he has a deep capacitance, 4 understanding! reminds me more of a run, start capacitors! this is why my A/C didn't work! I'm un-metered in my capacitance for understanding this! once dead, but soon 2 be risen again! yeasty!!
Please tell me you have an inductor substitution box of some sort to show off next. It just wouldn't feel right without the full holy trinity of passives.
@@IMSAIGuy Aw that's a shame. Well, maybe an idea for a future project at some point? I would have a blast just wiring up LC circuits with it to watch them ring at different frequencies. Nevermind the practical applications. Oh well. Thanks for sharing the R and C boxes at least. The wood makes them especially endearing.
Well I know with inflation and all, but i'm prepared to offer you $15.98 for that jewel. If you act now I'll throw in a book "How To Kill A Rat With an Oboe".... You come up with the coolest stuff. What great fun.
To prevent the possibility of a high voltage charge being discharged through a lower rated circuit, the next time you use it and select the same capacitance value.

@@VoidHalo that's a good idea, if not for soooooo many projects I've got in plans already :)

The box itself is pretty nice. I'd gut the insides and keep the box.
Great video! I build tube amplifiers and would find one of those very useful!

Maybe this box and the resistor box were used in a school teaching lab?

Looks like a bomb unboxing!
If nothing else, it is a pretty nice rotary switch . . .
I'll take it and the resistor box too.
I have always felt that the stray capacitance and inductance would make a capacitance substitution box not very useful.
Another good one.

May be several capacitors in this box are too dry to grant a good value…
way more than several.
Why must you discharge before switching vaules?

Where did my comment go? Did I anger the Holy Algorithm?
Jamesco.
The box itself is quite nice.
