Perhaps a cro picture ? I have a ,c, and b on together most of the time
Astable c controls all outputs frequency and phase in sync.
Im not able to get b inhibited by c as it should right?
All pulse shaping works ok .
I could have fake 4047's ? highly unlikely
what values did you use for the 4047 rc?
Its the same on both boards which almost rules out operator problem
Dave ...did you have any issues ?
I used 0.001uF and100k pots, that will give you 1kHz - 100kHz/ 2 = 500Hz to 50kHz on your Q output. But you can use many combinations. C is your control frequency, it has to be duty corrected before triggering the "A" and "B" oscillators. Remember "B" is reverse, if you have "B" ON at the same time as the others it is maybe the 4011. The duty cycles I have mentioned are REF: only, they are a point to start eg. 25%, 16.66%, and 8.8%, it is the ratios that must be the same. @ ALL The TPU is a parametric amplifier, remember the words of SM "it naturally runs with gain", that is not where the energy comes from because all amplifiers have gain, but are not OU. It is the means of extracting the ambient energy through the plasma, all along the solenoid coils with reference to the core there is an infinite capacitance change within the plasma. When it gets to "B", C2 is switched into the circuit, and from there on the parametric pumping continues within the continuing cycles. There is no race here as to whom first replicates, but everyone must realise how this works, it is an analysis of the circuit, and the most complicated part is realising the coil core varying capacitance. You can see it in the scope shots I have posted. Here are some others Regards Mike
