Paragon - LED pop

Hi All,

After my Pro10 issues with switch pop, I decided to try out a different 3PDT footswitch (A-3680) for my Paragon build. The switch was very noisy and I decided to try a softer switch ( A-5509). It got slightly better but I lost the daughter board for the footswitches as I couldn't successfully desolder them.

Here is the link to the <video>

My paragon build was with few mods - charge pump eliminated & C1, C12 to 10nF. Right/red side is high gain with 100K resistor & Left/Yellow side is regular gain with 1K resistor.

There are few things I tried so far but they haven't made much difference -
1) Changed C20 to tantalum capacitor
2) Changed LEDs, LED colors, size from 3mm to 5mm
3) Changed CLR R26 from 4.7K to 20K Ohm
4) AMZ method 1 to slow down the rush of current to LED

The switching is silent if I remove the LED.


I have attached some pictures. Please check them and let me know you see anything I might've messed up.

Thanks,
-AJ
