Newb layout question

[Bane]

I'm building my first amp. I'm building a 5e3 to get my feet wet before I dive into an 18 watt. I'm testing now and have run into a problem. I'm not getting proper voltage to my preamp tubes. I'm backtracking to to try and figure out where I went wrong and the first thing I'm seeing is I haven't done anything on the pins marked "Fil". I have no idea what "Fil" is. I've searched for the term and can't find anything. Can someone educate me please. Thanks in advance!

Welcome to the site!

Fil is short for Filament, meaning the heater wires. Tubes don't work without them.

Thanks,
Josh

Fil = filaments or heater pins. On 12A.. preamp tubes it's pins 4+5 and 9 if wired parallel. And on EL84 output tubes it's pins 4 and 5.
Post detailed pics of your build + voltages measured per tube and voltages of the B+ line

Wow. That explains it!! Sheesh. That was a pretty big miss huh? Going back over my layout, looks like I go from the lamp to each tube. No idea how I missed that, and I feel like an idiot for it, but thank you guys!

There are no stupid questions, just stupid answers, we all have brain-fades sometimes and often those brain-fades lead to a eureka moment, and the lesson is never forgotten thus becoming a better learnt lesson than if thought we understood it in the first place.

Heaters are in, now on to the next problem. Thanks again guys. That was a real "doh" moment:)
