Today the Dual Balter CV Gate Delay from Non Linear Circuits in the case.
I just change 2 things, the jack socket of the INPUT of the second, i use a switch jack socket to have the same thing on the 2 output when i don’t use the second in.
And also add a switch on the second for 2 values of capacitors (for long/short delay)
a patch with it
Here my stripboard layout
