I just finished up my [silent:arts] dual la2a
Just a couple little things to fine tune: I wired the pots backwards (not a big deal) and I need to adjust the trimmers. Also I should shorten up some of the power cables from the power transformer.
But the big thing to do is to get a 25k pot for the gain and use it in conjunction with a 75k resistor. The unit puts out so much gain I can hardly turn up the gain before it's clipping.
Overall it's very quiet. The right channel shows more noise than the left which might be a result of how I'm running some of the other wires carrying power. But it only shows noise when it's cranked - in normal operation it's silent.
1 question - what size fuse should I be using? I've got a 1 amp fast-blow in it now. If I turn it on with the relays engaged it'll blow the fuse. Maybe just switch it to a slow-blow?
I always seem to do something stupid in my builds. If anyone spots anything please let me know.
here's some picts:
