Hi all,
The Aleph 2 incorporates a 5 ohm NTC thermistor to connect chassis and circuit to ground.
Grounding chassis via a thermistor is in fact not allowed by European regulations, and I also prefer not to. I can easily isolate connector shieldings from the chassis, so for ground loops it should not be a problem.
It gives me the choice of grounding the circuit perhaps by an other means. I can leave the NTC, or maybe put a more fancy solution with a little switch or relay, or perhaps paralleling such a relay with a high ohmic resistor just to keep circuit ground properly referenced to ground, without allowing ground loops.
Does anybody have a suggestion?
Thanks,
Bakmeel
