hey thanks! no worries, whenever you get around... I was just thinking it would be nice to see how they used them.....
basically, i really like my 312 fabio boards with cinemags and 1731's..... but for some reason i have a feeling that the 312 circuit might just not be optimal for the 1731.... got to finish these fabio 2520bc's and test em out.
but yeah, i thought, why not see how melcor used em'
looks like slightly different input R, input cap (C3/C4) looks real similar, feedback R is a bit diff, and it's cap probably is just adjusted to match Freq response. zobel and what not, but thats dependant on the input tranny.....
then there's something between the opamp and the output tx to look at.....
so, if looking at the first schem miko just linked to, would it possibly be wise to change R4, R5, R6, C4, C5, and C6?
i guess thats one of those 'try it and see' questions.... so i guess thats my first task today.....
better question.... If I change those values, should my gain trim be something along the lines of a 15k rev log rather than a 22k rev log? or will a 22k rev log still work?
or, in my case, a rotary switch approximation of such.
thanks for the stuff.... can't read that eq schem very well, but i bet it'd be a cool project... probably switches will be the tripping point.
