TS is the same schematic of the complete vic tony is selling, stans schematic... but i changed some values because with those values it was not working for me... i used the components i got here standard values for example 100k 10k 10nf 1nf 100nf 1k 1M the only different i got is 2,2k all other values i make with combinations therefrom...
ohh the only difference is the gate pulse generator which is a bit different since i use the 555 and a 741 to make it.. like all my olders schematics
things only changed in the sense that now i use 4001 instead of sn74hc02 because the lm318 wasn't working so good at 5 v
I use only one 1/10 cd4017... don't see why use more...
you need to work with the components you got there you got it...
Well this is the most affordable stable and simple pll frequency generator i ever achieved...
I'm using mainly 9 IC components... cd4046BE, HD4001, Lm318, cd4017, lm7812, lm7815, ir4427, NE555, LM741 AND, some small signal transistors 2N3904, diodes resistors and capacitors
i use the 15v only for the ir4427 chip.. because its better to drive mosfets..
the lm318 is a direct replacement of the ecg918 which i could't buy here...
The best configuration UNTIL NOW i found to be
R1=10k pin11-gnd
R2=10k+200k pot pin 12-gnd
R3=100k pin 13-9
R4=10k damping resistor filter cap.->ground
R5=50k lock in resistor parallel with 1n4148 diode in the lock in circuit
C1=1nf - 11nf timing capacitor pins6-7
C2=20nf filter capacitor pin 9-> damping resistor ->ground
C3=10nf lock in capacitor
With this components, i could achieve perfect lock in indication and lock in condition from 500hz up to 250khz...
i think could go higher lowering the timing capacitor... worth for tesla coils..
At lower frequencies it become non stable... so filter capacitor can be increased for that situations... i believe max 100nf is enough..
