Manley Variable Mu Mastering Version’s Balance Trimpot?

[distorter]

Anyone know where is the “balance” trimpot of the Manley Vari Mu Mastering Version?
I am reverse-mod my 5670 unit back to 6386 version.
The instruction says: “Replace 10k "balance" trimpot with 500 ohm trimpot.”
But where is the 10k balance trimpot?

I wonder if anyone can answer the question. Thanks!

Try the bottom side of the pcb… the manual lists it between the 5751 and 7044 tube on each channel

Thank you for the reply. Mine is the very early version, I checked the bottom, only a 50k potentiometer right under the 5751 socket...
