KregB voltage slightly high (6.8V)

Hi there
I'm seeing the KregB voltage reading as 6.8V (vs. 3-6V range). Is this OK? KregA is 5.3V.
The amp sounds fine.
All resistance checks are fine and other voltage readings are OK. I've gone over the Low Current C4S wiring. All LEDs light up.
Low C4S
IA - 148V
OA - 77V
KregA - 5.3V
bRegA - 148V
IB - 149V
OB - 79V
KregB -
6.8V
bRegB - 148V
High C4S
IA 192/192
OA 148/149
bA 0/0
IB 0/0
OB 97/98
bB 148/149
Tip - 45mV
Ring - 50mV

Yes, that's OK. If the amp is new, you may find that with some time that particular voltage will drop a bit as the 6AQ5s cook in.
