I understand this might be an OLD issue, but I accepted a task from a friend who has had the board populated by another friend (based on original layouts given me). I finished the board and at some point found a newer layout titled REV 3. Following it I wired it up and installed. Well the amp fired up on first try (cool). BUT it sounds very constricted when you turn the volume up. Low power and ugly crackly distortion.
Now I can't seem to find any reference here to the BBRI stuff..... ?
Voltages are:

Pin 1 2 3 6 7 8

V1 194 1.5 202 1.5
V2 202 1 292 5
V3 209 23.5 39 199 24 39
Leaving the Trem tube out for this discussion....

6L6 3 4 5 6

V4/V5 414 414 -42.5 414

Comments appreciated and a pointer to the old info on this build also appreciated.

Any thoughts on this problem?

All tube test GOOD in a new Orange tester.

Hoping it isn't the OT.

The volume is extremely low, at about 7 it turns to a low volume ugly distortion.

Any help?

Have you checked the 470ohm resistor in the PI to be sure a 470k wasn't installed by accident? That's a classic mistake that is made on many new builds and your symptoms do suggest that.
