Those voltages look normal and the pop is fine.
Probably have a signal wiring somewhere. Check all the pots and switches.

Ah, i knew this would happen.. I'm missing the connection from lug 3 of the Volume pot. fingers crossed this is the only thing wrong

ok, added that wire. still no sound... gonna recheck wiring again.

The wire from the 2nd lug of the master volume to the power tube should be shielded right? It doesn't show it in the layout but its in the instructions. I have the shield grounded at lug 1 of the master volume. Is this correct?

This is the volume pot or gain pot( on schematic). The Master is the pot feeding the output tube. But yes Lug 1 of the volume pot is grounded and the shield is connected there too. The Master also has pin 1 grounded but at a different point in the circuit. I wouldn't think it neccesary for shielded wire at the Master volume location.

ok... in that case. I'm stumped. All the measurements are what they should be. and All the wiring looks right to my eyes unless I'm missing something really obvious...

I guess all I can do it go over the wiring again and again, and double check the bottom of the board... but if that was incorrect wouldn't that cause incorrect measurements?

Not if the problem is in the audio path. The voltages could all be fine.

Do you hear anything when you probe pin 7 of V1? ( probe with a meter lead or even a small screwdriver ect.)
stew

Just tried and got nothing.

How about pin 5 of the output tube. This spot is not as sensitive as the preamps so listen carefully.

I rechecked both spots... I got sound on both this time. I must have not heard it the first time.. so yeah. hum at both pins

Sorry if we've been here before but....pin 2 on V1? ( with all controls turned up).

no sound there. for sure this time

Then try pin 7. Then try pin 5 on the output tube.

Ok. Have a look at the schematic. You see the audio leaves pin 1 of V1 and is coupled to the gain pot via the coupling cap C2. It ends up on lug 3 of the volume (gain) pot VR1. It then leaves that pot on lug2, goes through R6 (330K) to the grid on Pin 7 .
Can you check that path backwards with your probe and see where the signal stops. Be carefull on the tube end of the coupling cap ...there's high voltage there!!!

I'm not getting anything at any of those points.. unless I'm doing something wrong

Ok.. we know there's a pop when you touch pin 7. So there's nothing at the other end of the 330K connected to pin 7 ?

no

When you prepped that shielded cable you didn't short the center conductor to the shield in some way? You didn't use the center lug on that connection strip next to the tube.? The volume pot doesn't have pins1 and 3 reverse wired?

no, no, and no.. Should I redo the shielded wire just in case? I believe I was careful to avoid shorts though.

Well you should get some sort of pop /hum/noise when probing both sides of that 330K resistor. Before ripping out that cable check that you don't get better results with the volume pot rotated the other way and the "tweed-tude" switch engaged.
