Typo in R11B formula in the previous message, correct formula is below. It was missing a parenthesis although LTspice didn't mind it.

R11A N014 N012 {1000*R11setting}
R11B N012 N017 {1000*(1-R11setting)}

I usually parameterize trimpots like the example below. Then you can use e.g. (0,1) range to try 0%-100% trimpot settings or change the formula to R11setting/100.0 if you like (0,100) range better. LTspice doesn't like 0-ohm resistors, R11setting of exactly 0.0 and 1.0 won't work in the example below. ?

I'm looking to go back to school to get a degree in EE and I'm previewing some courses.? Needed to familarize myself with LTSpice.? So I created the 100V from the 182T just to mess around.? Of course I also put a few of the transistors in backwards just like I did in reality a few weeks ago! lol.? But after fixing that, it works!? Unfortunately I don't think you can add trimpots, so you have to adjust the value of R12 to adjust the voltage.? Right now it is dialed in at 100.3V.? I created a folder called 'LTSpice' so people can add files for any simulation related to HP equipment.? I added this file to that folder.? I figured it could come in handy for troubleshooting purposes.
