EDUCATIONAL EXPERIENCES
				A series of interesting, educational experiments during breadboarding or PC Board assembly assures high learning involvement. The How and Why of each stage of electronic circuitry used is explained in detail, except Models 201 and 202.
Model 536 8-Transistor Radio	Complete the breadboard first..			MODELS WITH & WITHOUT BREADBOARDS
				All breadboarding materials, including the Graymark-developed Breadboard and solder pins, are supplied with Models 216, 523 and 536. If price is important and you don't want to breadboard the project, select the NO BREADBOARD (NB) Model and save; the same parts and manual are supplied, but breadboard materials are not.
..then do the PCB assembly	Finished Project
201 $14.95				202$16.95
RESISTANCE SUBSTITUTION KIT				CAPACITANCE SUBSTITUTION KIT
An ideal project for student, experimenter or technician. Substitute resistance values quickly and accurately for troubleshooting or designing circuits. Range switch selects LO (15 to 10K Ohms) or HI (15k to 10M Ohms). Two 12-step rotary switches allow selection of 24 different values.				Fast accurate selection of 9 different capacitance values from .0001 to .22 microfarads. Very useful project for troubleshooting or designing circuits. Capacitors are rated at 400V or higher.
