ABC's of Capacitors - Capacitor Tips for Tube Radios

If you need a higher uF than is available from your retailer, you can connect a couple of capacitors in parallel (side-by-side). For example if you need 200 uF at 450 volts you could connect two 100 uF / 450 volt capacitors in parallel and you would end up with 200 uF at 450 volts. You have kept the voltage the same while doubling the uF.

Outside Foil: Do capacitor manufacturers no longer mark it?

You can figure out which is the outside foil, at least on those types of caps for which it may make a difference. It does not in every type of construction. Just hook one end up to a scope, touch the outside of the cap, note the level of the noise. Hook up to the other end, repeat, see which is greater. That's the outside foil.

VFD Storage and Capacitor Reforming | KEB

Electrolytic capacitors normally have a larger capacitance value than other types of capacitors, and a leading factor of the capacitance value is the surface area of the anode foil. A process called etching is a specialized surface roughening procedure of the anode foil that induces a higher surface area and thus, a greater capacitance value.
