16Mhz Crystal Oscillator Actually at 16Mhz!

Again, due to the breadboard affects on crystals, my  circuit was slightly different than Alan’s by the lucky trial and error of my incorrect cap value components removal – including a floating caramic cap at the base of TR1 – at full PSU 30V before this thing kick started at a stable 15.9982MHz.

I removed the top 10nF cap and one 470pF (mine was a different value anyway) from ground., leaving one floating…(aerial!?). So touchy! Just connecting the probe ground can stop it..

17V gives a 1Vpp sine wave – if you don’t move anything!:
