Genuine "VitaminQ", Paper-In-Oil, Sprague Part #196P22491S4.
This VitaminQ capacitor is perfect for bypassing the output electrolytics in the MAX at CA8. Further, the cap is excellent as a coupling cap for the SOHA, bypassing the output caps in the Alien DAC, and any other coupling capacitor situation that is satisfied with the 0.22uf and 100V rating.
*** Note: These capacitors will NOT fit on the MiniMAX board if you use the designated Lansing enclosure. ***
Insulated, with an additional plastic outer wrap, glass sealed ends, paper-in-oil, they are 1-1/2" long and 0.42" in diameter - slightly larger than 3/8". They are NOS - New Old Stock and are excellent for audio applications.
Be sure to refer to the MAX website at Tweaks -> VitaminQ PIO Caps for complete details on mounting these caps in the Millett MAX for installation in the 3rd slot from bottom of the standard Hammond enclosure.
Beezar/Team Millett MAX recommends these caps as an excellent pairing with Black Gate electrolytic capacitors.
