Hey, you know, that's a really good question. My first thought response would be that the variable resistor is really big, but that leads to the ripple invert is biased to be slightly on all the time. Not for sure if it will ever go down to zero. It should but it might not. Also the ripple...

This should work.

It will probably just sample the line ripple and amplify it and invert it through a dropping resistor on its collector. Just a standard circuit. I wish I could find a better way of doing it since the ripple invert has to follow a variable output. Thanks.

You can end this tread now.

No problamo, as I have learned nothing from this thread. Shout out thanks though to Baluncore for introducing me to the schematics program. It works good. Thanks.

Want to hear a real fuzzy mental diagram. Mental dia: Got the power transistors stretched across the line and the ripple inverter transistor hanging from its base swinging like a monkey on a line. Only one or two leads to connect up now. Should I flip a coin?

Oh ya I forgot. I put a circuit breaker right after the transformer.

Hey thanks. I need to explain something here. I'm not that learned. My view is this. Lower alternating current off of the secondary then goes to a full wave bridge rectifier since I want it isolated from the ground so it takes 4 diodes. Diodes only let current pass in one direction, the...

Thanks, will do.

Hey, that's a good circuit diagram, only it's missing the ripple inverter transistor.

Thank you for all the help. Making and posting a schematic for something this simple seems to much of a hassle to me as I only need to connect two leads of a transistor up. Thanks anyway. I think I'll just go and try to figure it out by myself.

Also, what do you think of Pyramid's line of power supplies.

I don't know how to post a diagram even if I had one.

Transformer 30v 20a, bridge rectifier standard, filter capacitors 20k each, power transistors 15a each on top of each other with heat sink, and potentiometer from the high side to the base.

Are you sure. Sounds like you would like to insert it on the high side power line. That sounds like putting a secondary control before the control. Is this right?
