Just finished building the Plexi v6. With the exception of V3, all voltage checks ran nominally. All tubes are JJ for now (NOS for later). Measurements made with Fluke 87.

After reading through many threads, it seems as though V3 deviations are common with this build (or at least I've seen a handful of members experience similar issues). I've checked resistor values and installation. Everything looks good to go. Sound is amazing with little to no noise/hiss/hum. Haven't hooked up VRM yet since I wanted to experiment with the current setup.
Speakers are Celestion 12" G12H Anniversary 30W (8 Ohm) and Celestion 12" AlNiCo Blue 15W (8 Ohm).
I attached some photos of the build to showcase the craftsmanship that you can expect from Trinity. I am 100% satisfied customer. Thank you Stephen.
