![]() I decided to make this a proper control since I fiddled with it so much. This switch gives 3 possible release curves instead of the usual 1 (on a "real" LA-2A this switch does nothing useful.) The extra knob to the left of the Meter switch is the meter zero pot. Also, the Compress/Limit switch is a 3-position, center off toggle switch instead of the usual 2-position. This way, I could get closer to the precise amount of gain reduction I wanted in any particular situation. The two knobs to the left of the Gain pot are to trim each of the gain reduction elements individually. You'll notice some extra controls on Frank's front panel. It was probably the only way I'd get to keep one of my own compressors in my studio :-) I built Frank partly because I knew if I completed it I would never sell it. After building 32 or 33 "production" CLA-2As using PC boards, regulated DC supplies, metal film resistors and WIMA MKP-4 and Panasonic electrolytic caps throughout I wanted to build a unit using point-to-point wiring for comparison. ![]() The first prototype CLA-2A was built using carbon comp resistors and nothing special capacitors and didn't sound particularly good, but I did use it on some interesting records. Frank (short for Frankenstein, because it was built out of reject parts from failed experiments) is an example of design philosophy come full circle. ![]()
