little Help on my 1987 50W
Posted: Fri Sep 20, 2013 9:25 am
Hi there
I have recently assembled a great 1987 marshall replica following metroamp and SDM layout.
It sound very loud and great but I have a little hiss (like and oscillation) when I jump channel 1 and 2 and I increase channel 2 volume pot, near 3 / 4 .
If I connect singles input there is no hiss
I followed this layout : http://home.comcast.net/~jbjdav26/1987r17.jpg" onclick="window.open(this.href);return false;
and I have not used any shielded wire
cheers
Massimo
