Did anyone build this PWM or assembled after purchasing the PCB from Jolt? I still wish the component locations were marked/printed on the PCB for easy solder/placement.

Where are the 3 resistors on the PCB? Can you please point/label them with arrows?
R9 = 10k
R8 = 1k
R6 = 2.2k
 
 
Next I Solder 10Kohm R9, this will feed the signal from the next to be assembled voltage divider.

Next I assemble the Voltage divider by starting with the Resistor that goes to ground R8, here you can use between 1k and 4.7K

Since I don't have anymore 1ks, I do have several 4.7K. Since I'm using 4.7k to ground, I will have to use a higher resistor also to positive R6. and I'm usin 5.1Kohm.

but you can use the ones on the schematic
R9 = 10k
R8 = 1k
R6 = 2.2k

Today, i repaired the links to the pictures of this project.
I am building one myself now, as this PWM does NOT shift in frequency as soon as you tune the gating.


Its really a fine tool for everybody who wants to discover Meyer secrets.

I will use the 2n3055 transistor in stead off the FET's.
