Pair of genuine NOS Sprague 'Vitamin Q' PIO (paper in oil) Capacitors.

NOS, never used, full leads, hermetically sealed metal cases and with glass filled ends. Made in the U.S.A.

These are not the modern reproductions from the Tone Factory that you can get through Allparts and others.

Manufactured by Sprague, since the '50s I think. They are no longer being made. They were widely used in military electrical equipment and, apparently, in ICBM guidance systems. That's Inter Continental Ballistic Missile baby! They were built to be very robust and are not generally prone to leakage or drift. Vitamin Q's are regarded as some of the finest paper in oil caps ever made. These are highly sort after tone caps for guitar. They are hard to find and they are never cheap.

Superb Guitar Tone upgrade. Credited with giving 'woman tone' 'manchild tone', 'rancid overtone' and the even rarer 'axe passing thru cold chicken fat... tone'! It will also make your guitar or bass sound even more lovlier...

These both read right on spec.

Vitamin Q 91P
0.015 uF 400VDC

I added the old wirecloth insulation.
