General radio 1432-l 4-decade resistor substitution box


A 4-decade box, with 10 Ohms thru 10K Ohms per step. One knob has the pointer broken off, but all others are fine. The box is physically in nice shape - switches operate smoothly, no bananas are bent or broken, and with all the switches set at '5', you get the value shown in the pix. Pretty decent, and almost certainly individually better than the cumulative error of this particular test shows. 0 through 100K in 10 Ohm steps covers a lot of substitution ground. There's no rubber on the feet, but that's about the worst thing I can say about this fine GR box.
