Good point. It raises a philosophical issue about just when off is off. I will do Standby and On. No problem. I don't know EU regulations but it may be that less than 0.5mW is "off." Certainly is from a low energy perspective. By the way, the AC mains is plugged into a smart switch that responds to Alexa but obviously when I use that 3rd switch I don't see the red LED.

I should also mention that Mark's IPS#7 is installed in the M2X and some very gratifying and interesting listening is taking place by rolling not only op amps but pre-amps. More to come on the M2X thread.

Sharing another completed project using Mark's soft start board. It is doing it's job in my recently completed Tubelab SSE. Makes life easier on the tubes set for a 2 sec delay along with the piece of mind that only 5V is running to the push button switch on the front. I think the blue led power on "accent lighting" it provides is perfect using the spec'd resistor. Of course now I need to do something about those retina abusive white leds on the components to the left.

I am sure I have been one of the needier builders so a big public thank you to Mark for his generosity in helping me out!

Lovely build, spiggs. Congratulations! I agree with you, that eerie blue glow from within is very appealing. Well done and good on ya.
