First a question then an observation.
Has anyone been able to contact Mark or anyone from Core Tech? I have sent numerous emails, phone messages and I even sent messages through the Audiogon system with no reply.
My observation and a concern is that the 300 watt version that I have has NO ground connected at the output. With a power strip I plugged in a voltage tester and it shows an open ground. Thinking that my power strip may be the problem, I then tried an adapter to convert the IEC end to a AC 3 prong. Again, the voltage tester shows an open ground. Is this normal? Now maybe the transformer grounds the unit, but everything else after that has no ground.
