Non-Electrolytic CAPACITOR Tips. When replacing old paper/wax capacitors, you can''t go wrong using film capacitors that have a higher voltage rating than the paper ones you are replacing. For example, if you are replacing a paper capacitor rated at 400 volts, you can use a 630-volt film capacitor (but not a 200-volt capacitor).

There are two styles of wax potting. First is just dipping or soaking in wax. It generally coats a few layers into the bobbin but leaves a lot of it without feedback protection. That can fix most of the feedback raising the ''quality'' of the pickup. The best method is to vacuum pot a pickup where the pickups are soaked in wax while a vacuum is

I kept it and it is still in there. I kept the radio mainly because I couldn''t believe it had a good paper wax capacitor in it. (Also the styling is to die for.) The radio works great. I have an article from 1950 CQ magazine on paper wax capacitors. They describe them as relaible. That got my attention. Moisture is the main culpret here.
Encase the pickup windings in wax, and the sound takes on more characteristics of the wood, with a rounder, fuller tone. Not that we''re saying the wax-potted tone is “better.” Tone is subjective. (Try potting a Danelectro pickup some day. You''ll singlehandedly destroy all of its mojo at one fell swoop!)
Rotary variable capacitor Rotary variable capacitor: several rotor positions.. A variable capacitor is a capacitor whose capacitance may be intentionally and repeatedly changed mechanically or electronically. Variable capacitors are often used in L/C circuits to set the resonance frequency, e.g. to tune a radio (therefore it is sometimes called a tuning capacitor or tuning condenser), or
Some of the wax paper capacitors looked a bit sad, and had started to dribble wax onto the tag strip, they would probably need replacing. With the capacitance meter in hand I started checking the values. The first one to always check is the grid coupling capacitor on the audio output valve. If one is going to be faulty this is it.
