This video demonstrates how I built a nice looking and fully functional electrolytic capacitor discharge tool. Electrolytic caps can store high voltage even after the amplifier is turned off and such voltages must be drained before any work is started on any valve amplifier. The tool can discharge voltages up to several hundred volts or any lower voltage too. Highly recommended for amp techs and beginners alike.
Nice Job! I'm going to make one of these, can't have too many cool little tools, especially one to keep from getting zapped by a cap!
Yep, my last one fell to bits, this one should last. Thanks for your comment.
Would be great to see it in use!
Thanks for making this video. Why use a brass rod? Is there a particular reason why you used brass? Thanks
Hello William, I chose brass as it is a better conductor of electricity than say steel or aluminium, it is often used for screw connectors due to it's strength where wires need to be joined. Copper would be a good choice but is a softer metal. Brass is readily available in this type of rod. Thank you for your comment.
I use five 100ohm 1 watters in series, works a treat as they say
what you take like rod .thanks
100 Ohms !!?!! Discharging a 2,100 V, 1 uF microwave cap would fry this despite the nice construction.
Hi Colin, yes, I believe you're right. It's no use for such high voltage. But this is designed for tube/valve amp use. Thanks for your comment.
FYI, you keep referring to the resistor as a capacitor...
Thanks for the note, I looked at the video and you are correct. Getting old! Unfortunately I don't think UA-cam allows you to edit after publishing. I'll have to see if I can add a correction title at the points where I say it. Thanks for the information.
