How do I discharge the capacitors in my PS audio P20 ?

@frankmc195 If I had to wait 24 hours every time I needed to work on a tube amp...

Erik has the correct answer. Then after the wait ...

noromance... this is do as I suggest not as I do. I have a 12 guage wire open at both ends taped to two round dowels and I just touch them to each pole. You do this at your own risk as the capacitor may go away. I haven't had it happen but it can. Now if I had suggested what I do, I would have 30 on this blog telling me how dumb I was to suggest such a thing.

How will the capacitors be recharged with no power applied to unit. I worked as a audio repair tech for 40 years and it always worked to drain off power supply charges

They won't, of course. I misread the question.

Shorting a high uF cap directly is a bad idea. You can in fact ruin an otherwise good cap.

Also, worth noting the voltage rating on a cap. If it’s 50V say or less, it’s not that dangerous.

If you don’t have a 10W resistor, just use a bigger Ohm resistor and wait longer. What’s the big deal?

Lastly, why on earth is someone who doesn’t know how to measure or discharge a capacitor safely getting into the guts of an appliance?
