Hi all, First time poster here. I just built my first kit, a 5F2A from Mojotone, and got a lot of help from @theprofessor's build thread. I've got the whole thing wired up, and am now checking voltages etc. I have wall AC at the fuse, and the right AC voltage at the tube heater wires. I also have high voltage at 4&6 on the rectifier (around 325V measured to ground for each). But: - The rectifier tube isn't heating up. I did test it (2 to 8) and it does have continuity. - I'm not getting any voltage at the filter caps. What's my next step to troubleshoot this? Thanks so much!
