Set/2 knight resistance &capacitance substitution boxes
Dad kept these safely stored away in this red/white/black plaid zippered cover, which will be included. Since Mom and I do not know anything about these, I must rely on the pictures to show you. I will describe these as well as I can. Both are "KNIGHT" by ALLIED RADIO CHICAGO, made in the U.S.A. The Dial on the RESISTANCE SUBSTITUTION BOX, starting from bottom left moving up clockwise, can be set at "15, 22, 33, 47, 68, 100, 150, 220, 330, 470, 680, 1K, 1.5K, 2.2K, 3.3K, 4.7K, 6.8K, 10K". The black switch toward the bottom can be switched to either "x1" or "x1000". The Dial on the CAPACITANCE SUBSTITUTION BOX, starting from bottom left moving up clockwise, can be set at ".0001, .00022, .00047, .001, .0015, .0022, .0033, .0047, .0068, .01, .015, .022, .033, .047, .068, .1, .15, .22".
