Re: Sugden preamp WAL AC Farnell.
Latest update.
Delighted to hear that the manufacturers are sure that it was designed by Jim Sugden.
Advised that a variac can sometimes cause instability issues.
Plugged it in to the mains and no smoke or pops to report.
However, can anyone suggest some DMM readings that I could perhaps take from inputs and outputs that might offer me some reassurance prior to connecting it to source, amplifier, and speakers?
