threshold voltage, so you would control that with two resistors, one
between positive and the gate, and the other between the gate and...

usually a fixed resistor value of 220 ohm is used, with a 5k trimmer.
Is there any problem if I use a 450 ohm resistor with a 10k trimmer?
Maybe the current on the regulation pin will be too low? An...

I'm trying to program a PIC 16F628A using a Matrix Multimedia HP488
