Well, I finished up all my soldering/components installation yesterday, and fired up the amp for the first time today....no sound

No hum, no buzz, no nothing.
Now, after a PM from Coco, I realized I installed the shielded cable incorrectly - would that contribute to my lack of sound?
Here are my voltages as well (recommended voltages in brackets). Any help from you experienced builders out there?
Voltages:
V1
Pin 1 - 133 (120)
Pin 3 - 2 (2)
Pin 6 - 136 (123)
Pin 8 - 2 (2)
V2
Pin 1 - 167 (167)
Pin 3 - 1.1 (1.1)
Pin 6 - 210 (175)
Pin 8 - 50 (70.5)
V3
Pin 3 - 377 (380)
Pin 4 - 349 (338)
Pin 8 - 22 (22)
V4
Pin 3 - 380 (382)
Pin 4 - 349 (339)
Pin 8 - 23 (22)
Any suggestions?
