CONNEX Socket 8-pin, Octal (KT88, 6550, EL34, etc.)
CONNEX Socket 9-pin, (12AX7, 12AU7, 12AT7, 6DJ8, etc.)
Look like the same thing to me and while PCX's price is a bit higher I'll contact them about quantity discounts over the 25+ discount they list on their site. How many of each are required for each amp?
