[sdiy] Tube amp cap discharge tool?

[Ralph]

Hi Michael,

Get a 10 watt 1000 ohm resistor and solder it to a piece of wire with an alligator clip at the other end. Place the alligator clip at ground and use the lead of the resistor to discharge the cap. This is safe with any tube amp. We have been doing this for many years.
