I did use 5952s, the voltages on the JFET gates change based on the trimmer, the source and drain are both 0, all of the voltages match the ones at the end of the build docs. Here's a pic of the solder side though it's a tight board so idk how helpful it'll be

The stuff near the trimmers is a few straybdog hairs lol.

I'll try pressing on the JFETs, but they're getting power so I don't think that's it

I just finished building the Tractor Beam, but can't get any phasing no matter what I do with the JFET trimmer. The level trimmer also has no effect on the output, nor do any of the external pots or switches. All of the voltages match up to the ones in the build doc more or less (a few are a little low, but not crazy), I tested the voltages on the switching board prior to wiring and they're also good. The one weird thing is the voltages on the gates of the JFETs don't vary unless the trimpot is adjusted (they don't vary with just time the way the ones on the ICs do). I bought a quad matched set of JFETs and checked them myself, so that's not the answer. I've attached pictures, any suggestions are welcome. Thanks!

I recently bought a few VFE boards and am getting ready to put them together - I'm looking at PPP, and the price seems reasonable for the enclosures, a little higher than what I normally pay, but not crazy (~$15/each), but the cheapest shipping option is UPS ground for... $24. Is this normal from what you've seen? It seems strange that ground shipping would be anywhere near that. I love getting pre-drilled enclosures if I can because even with a press, I kind of suck at drilling, but I don't know if I can justify $27/each for bare enclosures lol.
