I'm curious about whether an active or passive equalization scheme is used; and if there are class-A gain stages utlized within. Curve accuracy?

Been along time since I took the cover off it. I was hoping for some quick info if it's handy... Thanks in advance.

It sounds nice with 47kOhm, 25pF custom input from my TT leads....maybe a little dark but very sweet and musical.

Try input 2. 1 is 50K and 2 is 100K for different tone colors.
