SEX3 page 61 glow test fail

[dkazakoff]

Hi there. I worked through the manual to page 60 passing all tests and checks until now. At this stage proceeding to page 61, I've inserted the tubes, connected power, and the tube filaments DO NOT glow. Checked the fuse, tried swapping it out and back again with another. Tested the switch again, passed. Checked terminals L and N, 120v. Couldn't get the tubes to glow, so thought I would proceed with a few voltage checks to try to narrow it down. Here is what I get on the first 7 terminals:

TERMINAL / V TARGET/ MY V
2 / 65-95v / 383mV
3 / 15-18 / 0
4 / 0 / 0
5 / 0 / 0
6 / 385v / 276mV
7 / 400v / 275mV

I'm considering re-wiring. Can I use a higher gauge than the 23awg which comes in CAT 6e? (I'd like to use 20 or 21 awg)

Let’s focus on getting the stock build to work before you swap in a bunch of different parts. Can you post some photos of your build? Good lighting, a nice overhead shot, and some close-ups of those terminals that are way off would be a great start.

Definitely post build photos and the voltages you see on the H1-H8 terminals.

I would not rewire the amp, and it's a bit of an odd question, as there shouldn't be any of the CAT5 wire installed yet if you are on the glow test stage.

Ok, here are some photos--> https://drive.proton.me/urls/4RMXVARJK4#cIWy9DnEmSOi
I can upload them here as well if that is better for you let me know.
