hi all.
just reporting an ssl 9k mic preamp build. (keith andreus schematic)
so i have built this thing ,using a tl72 for the tl51/52(impossible to get)
and powering it with the +/-18v rails.(i also left out the cx capacitors)
the gain of this thing is really high...so noise is high too...(i guess..)
ive tested it with the unbalanced output,into a crapy soundcard,so i dont know how much of this noise should really be there...i also have a noisy
computer next to the mike so...
can someone point out how to perform a noise measurment,using a windows scope?or some tips on this build?any entry will be apreciated!
