Can we see some photos of your build?

What was your measured AC mains voltage?  What did you wire the amp for?  Where do you live?

What kind of meter are you using?  If you try to measure a fresh 9V battery, what DC voltage does it show?

And make sure you have the meter set to measure DC voltage, not AC voltage. The DC symbol is usually two parallel horizontal lines, one dashed and the other solid.

cheers, Derek

Resolved. Thanks guys. First time through I didn’t have set to dc then I got that going. Turns out I had the cap on pins 6-7 backwards. And had a bridge on the 9 pin tube. It’s up and running thanks
