Friedman JJ preamp tubes

[abbath78]

Recently picked up a JJ100 in a trade- what a killer amp! The other night I took off the back cover to check out the tubes and noticed that the preamp tubes were an assortment of different brands. So I'm wondering, what preamp tubes come stock in the JJ?

V1, v2 are jj and the other 2 are Chinese. All general ARS branded but early on the jj ones were Ruby.
