CAPACITANCE SUBSTITUTION BOX

Comprising 12 non-polarised capacitors ranging from 100pF to 0.47µF (470µF) using standard preferred values, in step ratios of approximately 1:2 Selection is by means of a rotary switch and external connection is via a pair of 4mm sockets. All capacitors are of + 2% tolerance, 250V d.c. Working with values as follows : 100pF, .001µF, .0022µF, .0047µF, .01µF, .022µF, .033µF,.047µF, .1µF, .22µF, .33µF, .47µF.
