Been lurking around the trinity site for a while now. Finally had time and money in the same space for a build. Let me know if my tired eyes are missing anything as I go here

Looks good so far. Didn't check the values on the board tho.

Caught one mistake I made on the layout. Too many long days at work and only getting nights on the amp once the kids are in bed. Just checking in on the buffered loop. Am I reading right that I would run the line from the master V wiper over to the board, and then from the board down to the lug with the v3 resistor? Loving the build so far. Even my kids are getting in to watching it progress

Run the coax from the master wiper to the Fx board then run some coax from the Fx board to the 22K.

Good morning /afternoon to you. I just preformed a start up on the triwatt.
I ended up using used tubes as I am waiting for some tubes I ordered to come it, and I have a couple questions, 
I have 12ax7's in v1-3, at7 in v4 and old RCA 6v6's from a garnet amp in for power. 

My readings are

V1 1:132
       3:1‎.3
       4/5:3
       6: 118
       7: 0
       8: 1.1
V2 1:199
        3: 1.2
        4/5:3
        6: 126
        7: 0
‎        8: .7
‎V31:287
       3:1‎.6
       4/5:3
       6: 190
       7: 0
       8: 1.6
V4 1:286
        3: 76
        4/5:3
        6: 265
        7: 38.8
‎        8: 87.3
V5 and 6
       2:3
       3:471
       4:437
       5:-32
       6:-32
       7: 03
     
      ‎Now I suspect when my new tubes arrive, these will change a bit. Most seem within spec as I read it, 
But v4, 5/6 seem to be a bit out. 
Do I wait for the new tubes
I should also say, I missed a couple jumpers on my initial start up, I did have a little heat from the Zener diode area. Once I have some time, I will be looking at it again. The jumpers I missed were between 620k and 180k next to the diode there, the one between the 2k2 and 7k5 near the bus bar

It does fire up, and I did plug a guitar in, very low noise floor, and the tone is ‎beautiful. I am excited to get it finished once I have some more time to set aside for it.
