Possibly the RCA connector on F6
With RCA disconnected from the B1, 10.6 ohm from RCA pin to the chassis
On the pre side, 2.6 ohm.
I will try to reinstall the RCAs.
your link to the SMPS was to an open chassis supply
I am assumming that it is completely open. I even put an isolation trans infront of it.
is its chassis grounded or floating
chassis is floating...not connected to the pre chassis at all
yes,you got this right.75,000uF per rail? That's 150,000uF for the amp, yes? 0.15F? Did I get this right?
I need to think more
Me too...
The B1 board is connected to the pre chassis! Do you think?
Nope. that's not it. I just checked

Do 3 more measurements
1) Measure resistance from Meanwell 0V to chassis of Korg Pre
2) Measure resistance from Meanwell Chassis to Korg Pre Chassis
Edit 3) Measure resistance from Meanwell 0V to Meanwell Chassis
Include these measurements in the drawing
If you do this someone will see where the problem is. My brain is fading (lack of sleep).
It will be easier for everyone if you draw what we have so far.

yes. no readingDid you measure across your RCA cables
1.6 ohm1) Measure resistance from Meanwell 0V to chassis of Korg Pre
2) Measure resistance from Meanwell Chassis to Korg Pre Chassis
no reading. Meanwell sitting on a wooden platform...glued it

no reading.
I've been working on this all day. My brain is shutting down too.
Do you use a 3 pin plug or 2 pin mains plug with the Meanwell psu?
I am using a 1:1 isolation transformer to supply AC for the meanwell. I thought it would isolatate any possible ground issue and safe as well.
3.Do you have a mains cable with 3 wires
2 to the isolation
1 to the chassis (I am thinking that this may be the cause)...cut off the safety wire to the chassis?
I will connect the MW directly to the main power.
