ok, i have bridged R6 (100k) with 1k and then with 100Ohm, not a huge difference but pulse width now dips much closer to both 100ms and 200ms although still goes to as high as 130 and 230. So if i take the average value, its more or less the same, maybe slightly better, it just get much closer to target values than before. when i connect everything, first 1-2 pulses get to almost exact values, the they get wider... capacitor? Many thanks, Alek |

Then, please, poke around with your scope probe along the signal path and post the waveforms so that we can try to figure out what is going on with the circuit. |
