NOS sprague black beauties

How can you get a great tone without a good understanding of what makes your amp tick? — EL34, EL84, 6L6, KT66, KT88, 12AX7, 12AT7, 12AU7, EF86, Output Transformers, Power Transformers, Capacitors, Resistors and everything else that it takes to make a tube amp sing!

Hi guys, im trying to clear some stuff up on Sprague black beauties.
I came across a bag of NOS beauties. But they seem different then ones ive seen. Instead of molded cases they seem to be a phenolic tube sealed on one end with epoxy. If im not mistaken these are the first generation black beauties from 1954-1960?
Only one 0.022uf cap. The rest are 0.01, 0.068, 0.1, 0.25, 0.33 and 2.5uf@ 600v.
What use are the large value caps? i have never used a tone cap larger then 0.1uf cap in a guitar amp. :thumbsup:
