And only my second preamp built from scratch. Finally got round to finishing this. Built as detailed in the TapeOp article. 2 JFP stages on a tiny pad-per-hole perfboard in a little box. Everything was recycled or from the piles of stuff I grabbed at my local RatShack store that was closing. Overall, super cheap and cheerful.
Input transformer is a UTC O-16, the switch to the left is pad, the knob to the right is Gain. The jack on the left, with the beige cable is the power input. Box is recycled, I traded a burrito for it, and it already had a nice 5k pot in it.
Big white caps are 10uF mylar. Output is unbalanced, I tried to fit an Edcor WSM600:600 in there, but no space.
Power Supply. Now I just need to add a seperate little regulator board in there for phantom. RatShack project box cost a dollar, the tranny was six dollars. Could I be any cheaper? :green:
Must thank everybody who discussed this project here. Especially, Matta, ChrisSugar, buttachunk, Bauman, and (of course) PRR.
