Schematic design of X'Tal Tester
Part Components of Mini Audio Amplifier:
Capacitors	Resistors
C1,2   =  220 pF Ceramic C3,4   =    10 μF / 25V RSM C5      =  100 nF Polyester C6,7   =    33 pF Ceramic  Semiconductors IO1     =  4060 IO2     =  74HC4060 IO3     =  78L05 T1       = BC547C D1      = LED 5mm, Yellow D2      = 1N4148	R1,7   =    1M Ω ¼W R2,3   =  5,6K Ω ¼W R4      = 220K Ω ¼W R5      =    1K Ω ¼W R6      =   220 Ω ¼W Misc S1      = Push button (normally open) S2      = Two-positional switch
Notes:
This circuit enables you to test quartz resonators at the range values from 32kHz to 24MHz. Confirmation of good state of quartz resonator is done by diode signalling LED and acoustic signal. Switch S2 enables change of range.
