Hi, I need some help
I have some gain problems in my unit, I cheked the previous posts concerning about gainloss but didn't help.
So when the unit is bypassed the gain is normal but when I put the eq on the gain drops about 10db's, it's the same with both channels and it doesnt matter if i use balanced or unbalanced jumpers.
I have a stepped version using harpos xls values and the only thing different is that I'm using green pre psu with +-15v rails.
I just have cheked all my caps, they are the right value no errors there, also cheked solder bridges, all fine.
And measured all the ic pins and +-15v were on the right spots, I'm using JRC 5532d/5534d's
Do you have any pointers that I should check?
Edit...I also checked all the resistors with colour charts, all fine there and measured the ic:s hey were fine also.
So I'm litlebit confused and I was thinking that did I made some mistake using the rotary switches? I used Harpos xls v1 to calculate the pot values(no parallel resistor), I used 11 step lorlins and the center is normal 56k2 the rest of the build is done exactly by the bom. Did I made somekind of mistake, do I need to change some other parts to make the switched version to work normally?
