New Foreplay build Questions

Hi, My OD3 is glowing but the 2 12AU7's don't. I'm getting only 2.3 VAC  on 4, 5 and 123.5 on 6 of the transformer terminals. The wiring looks good. Any ideas?

Check the orientation of the diodes and the capacitor back there. It has been a source of difficulties a few times. If there is an error, check the diodes and inspect the capacitor for signs of swelling - they may have been damaged.

Thanks Paul. When looking at the capacitors I found a solder I just plain forgot. All the tubes are glowing.
