Vix said:I run my ZV9 with a "passive" pre (ok. a cathode follower), but my ZV9 isn't really a ZV9, because I run it without feedback, hence its a transconductance amp with a higher gain than "stock" ZV9. With Visaton B200's in an OB, it gets loud enough.
The sound? It's a cross between an F2 and ZV9, just what I like
I'm currently building a feedback-less F3 amp. How much more gain did your feedback-less ZV9 have ? Did you change much more, besides removing the feedback cap and resistor, and replace the input resistor with a resistor to ground ?

feedback (47K) resistor until you're happy.
