I have a difference in DC voltage after regulators on B- And B+ rails in my Sony TA-E90ES preamp. On B+ side I have 22.50VDC and on the B-side -22.59VDC. What kind of impact can difference of 0.09VDC make on preamp performance? What is causing this difference (resistor's value?)and how can I correct it?
Sony's manual shows the same voltage.
Regulators NIC 2SA985 and NIC 2SC2275.
Any help or suggestion on this matter would be greatly appreciated.
Thank you in advance.
Bo
