how much if any does gain increase/decrease with psu voltage ?i went from the stock 40db to 60db and found that the cartridges were overdriving the opamps and causing distortion.
40db just wasnt enough with my passive pre.
so i went for 50db and everything is great now.
i want to to replace the 2 9v batteries with a pair of 12v 24ah sla and just wondering if the extra voltage will increase the gain anymore.
and can i just series the +/- rails on the board to get a 3-conductor to connect to the seriesed 12v sla or do the 12v sla have to be connected separately like the 9v batteries ?
the board looks like dual-mono but i thought the opa2134 needed +/- rails.
im thinking 1 of the 9v is reversed in the circuit ?
thanks.
