Thank you so much ,not too many detailed videos about repairing volume control is on UA-cam, I certainly learned enough to roll up my sleeves and fix my scratchy potentiometer. Thanks again
Thanks for the kudos Bahram. One thing I might add is to NOT use DeOxit D5 on the carbon track because it may dissolve it and end up making it sound scratchy. Best to use DeOxit F5. The "F5" designation is for faders.
Some people have asked what that Orange Drop capacitor is with the coil of wire around it. A: It's my home-made replacement of a very unusual (for me) shielded audio coupling capacitor. I just wrapped a single strand wire around a standard .022 mfd. cap and ran a bead of solder down both sides of the coil wraps so as to make it a shield for the capacitor which is supposed to keep out any hum.
I know Deoxit full strength will absolutely destroy carbon pots. I ruined several with it before I figured out what was going on. I never gave the d5 a chance before I went back to using regular contact cleaner with light oil.
I don't think D5 is all that strong to where it will destroy a carbon pot. Could be why they released F5 for faders. I'm still using the pot shown in the video everyday on my Zenith FM radio and it's doing just fine. Thanks for the reminder though, sometimes I just grab the D5 out of habit when I really should use the F5.
DeOxit FADER LUBE is designed for Rotary & Linear Potentiometers. Beginning in 1970s, manufacturers began to switch from Carbon to Conductive Plastics. Stong Solvents MELT the plastics - destroying the control.

Good channel and great video! Thanks for sharing.
Thanks Lori!

I so want this dude's workbench and equipment!
Thanks man. It took me 70 years to collect it all.😂

Mini channel lock= Ignition pliers of old, pre electronic ignition~
What do you do when all the carbon is all worn off.
The only thing you can do is rob another resistive element from a similar pot.
I would mark where the locking tab goes. I tend to forget at my age
Me too. Thank God for handy cell phone cameras, I photograph everything!
