This circuit generates sequence of pulses in order and times determined by the capacitors in pins 6 and 7 of each timer. The circuit is from an old Mullard (Philips) manual.
SIDACs are not very common, but if you get one you can mount a relaxation oscillator capable of...
The voltage gain of this circuit is 1,000. This gain is given by the ratio between the 10 M ohm...
