And it's also for the the '01, but not the '149. On the '291 I put the "0dB" trim pot on the board instead, there was no way with the new circuit arrangement that we could use the trim pot on the '611.
On the '01 and '241 you adjust it for 0db with the gain pot in the centre position.
I'm now trying to remember what the heck the '241 actually was...I haven't got a circuit for that either! (hint, hint...) I seem to remember it has a transformer on it??? I'm pretty sure it was a 1986ish Trevor Stride design (like the '242 EQ was).
Cheers,
