I'm getting ~117VDC @ 0A and 0B on the large SB board (spec 75-100V). This is outside of the 10% tolerance stated in the manual. Is it a big concern? If so, what do I need to look at? This is a stock build, no crazy mods. TIA

Often when we see that it is a combination of a very strong 6080 tube and a moderately used 12AU7.

Gotcha thanks. So basically don't worry about it?

I wouldn't, especially since the OA and OB voltages on the big board are about the same.
