DIY Capacitor Discharge Tool for Tube/Valve Amps

[@greggsvintageworkshop8974]

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

[@dembydish]

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

[@kubockferre5532]

what you take like rod .thanks

Use a 1k ohms 25 watt capacitor and insulate it from the brass/copper bar. Matches? Oh geez; buy a heat gun and make a clean shrink. I prefer using 14 ga. multi-stranded wire and not chessy thin 20 ga. garbage from Harbour Freight. 14 ga. woven wire is even better for flexibility.

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 KZbin 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.
