Do both halves of the 12AU7 glow?  Can you post some build pics?

 

[John.soriano]

I have included pictures of my build,
it looks like both halves of the 12AU7 glow, not sure how bright its supposed to glow though, i added a picture of it as well

also please excuse my beginner level soldering skills

You'll want to trim the twisted leads on those 3K resistors for sure.

If you measure the DC voltage carefully at A8, is it 0V or about 12V?

 

[John.soriano]

Trimming the twisted leads has done the trick and both LED's are now lighting up, i feel silly now. appreciate your help!

That shouldn't have fixed the issue, but if you have a loose connection somewhere that may have temporarily made things work properly.

I did find a connection that i forgot to solder, now working perfectly, thanks for your help Paul
