Hi This voltage will depend on the tolerance of the 8 volt regulator. If the 8 volt supply is on the low side of the tolerance then you will not be able to reach the 3.8 volts. However 3.75 should be close enough as this is just a ballpark adjustment. The final adjustment will be made later by turning the AGC on and off and adjusting for no change in the background noise.
