...and the controller (SG3525AN).....
All the 1/4W resistors are Dale RN55s, 1% 50PPM, and the electrolytics are Panasonic HF series. I plan to change the IR IRF540s out and replace them with some old Motorola IRF 540s so that I can say that all the semi's are Motorolas, as well.
The pc board was purchased from Old Colony sound, before it was discontinued. I'm quite sure that Old Colony does not have any nore boards, as I got this one about seven years ago.
