We stick a Vintage 40's sprague PIO .06MFD cap in a newer Tele ... what happens ? 

That's a big boi. Clipping/starving the top end nice. Sag

Interesting. Thanks 😊

I just put together a Tele control plate for a friend with a Russian military PIO .047 uF, about as big as the Sprague, we haven't tried it out yet, so this makes me excited to get it wired in and see... or hear hehe... I'll be disappointed if it's a dud.

Please write in response what are the markings of this resistor and capacitor. Thank you.

was that cap electro;ytic?
