Yes, sir. Great! I’ve had a few cold solder joints in socket pins and other spots, too. For my builds, that’s usually the issue.Finally found the issue!!
I noticed that the tube wasn't heating up as much as the other tubes. The left hand triode finally started conducting when I reflowed the solder on its heater pin. This is despite me testing and re-testing each socket pin with a probe on BOTH top and bottom.
Thanks for all the help and suggestions. Lesson learnt about cold solders!
