Path Audio Resistors - Capacitance ?

Hi Everyone,

I've been reading up on the Path Audio resistors. It seems they are not pure resistors, but deliberately designed as resistors with capacitance. That 3rd lead will bleed off high frequencies. 

If anyone has a pair and can measure the capacitance I'd be curious to know. 

Best,

Erik

Usually when I see a tube, I think there's a coil, or a cap hidden. It would be nice if someone could measure the L and C on those "resistors."

It is a high pass filter and Faraday shield. 

Read up on either. :)

Hi @jhrlrd -

You are right, but what you don't realize is that you are essentially describing both a faraday shield AND a capacitor. :) 

What is a capacitor but two conductors separated by insulators? The copper shield adds capacitance. Same thing happens with shielded wiring by the way. 

What I'm wondering is whether or not this is measurable as capacitance. If it's tiny it won't make much of a difference. 

Best,

Erik
