But I am a little confused by the way you have shown the results too, I do not understand what 'and 0.5k' or '3.3K to R7 to pin D' means.

So as there are no numbers on the resistance picture on post #404, can you check them again and record the values please? Alan
All measure are form the gound.
I measure 3.2K between R5 and R7
I measure 500 Ohms between R7 the pin D of Q2.
I measure 3.3K between R5 and pin G of Q2.

Sorry my mistake.

No mistake, just a different method I think.
And I am still not quite with you yet. So let's try something else.

Unsolder one end of R7, measure its resistance. (Should be 10k)
Next unsolder one end of R5, measure its resistance. (Should be 100r)
Leave them out of circuit for the next test.

Now put the Black meter lead on the ground wire.
Measure the resistance from ground to S, then from ground to G and again from ground to D of Q2.

Let us know the results. Alan

Perhaps Jason, future designs can use an East - West switch position instead of the North - South currently used.

Why? There is a unwritten standard for audio equipment power switches, it's up, in, or clockwise to turn power on.

In or clockwise is common for on but outside the US - down is common for on. Lots of countries outside the US have powersockets/outlets with switches on them that operaate down as on and the same with light switches.

Vive la difference!

Yes, I agree wholeheartedly and completely.

I did specify audio equipment, not light switches/mains outlets/etc...

I have never seen a 'down - on' light switch: not in South America, not in Europe I think either.

I would switch off every light, every time I wanted to turn something on!

It has to be down for on otherwise how do you see the red dot on top that tells you it's switched on? Plus, my toaster is down for on!
