IJ Research TG12413 51x Limiter

Projects > IJ Research TG12413 51x Limiter

Igor’s clone of the EMI TG-12413 Zener Limiter for the 51x Alliance format. Igor’s version hews as closely to the original EMI schematic as possible, with a few modern additions. Because of the “beastly” requirements of this unit, Igor’s module is compatible only with the 51x Alliance racks (not 500-series) and requires two slots.
