Preamp schematic check [message #80774]

I found a preamp that I'm thinking of building because I have a stack of 6SN7's and VR tubes. No better reason right?

Anyway, it's a BEZ Q4B preamp that comes from China, point to point wiring handbuilt by the designer, and has gotten some pretty good reviews from the people who have bought it over the last 10-12 years. It's simple, I can kinda follow a schematic, but I always layout a wiring diagram to help me visualize. Actual layout I can do, just the wiring bit helps me not screw up. So here's a few photos of one of the preamps, it's innards I could find, the schematic, and my little diagram. IF anybody has the time to check my wiring diagram I'd appreciate it.
