Hello 
I am new on the Board.
After some years of Pedals and Amp Restorstions I started my First Full Build.
Unfortunately i got some troubles with my SLO build.
The Problem is:
Without a Pedal in the Loop the Amp works Fine. Even with a Patch Cable only in the Loop it works without a Problem.
But if i put a Pedal in the Loop Everything that comes out of the speakers is annoying hum. Nothing Else, no Guitar Signal. It doesnt make any difference which Pedal i use… on the other Amps they all work Fine.
I think the Layout on the Jacks is Right.
In the Rosamp Layout it looks like the bare Shield is connected to V4 Pin 7. that didnt make Sense to me so I connected the red wire like on the other Parts. Maybe here is the Problem?
When This Problem Happens I wont get Sound from the Amp Even if I restart it. It is only some whispering low Sound noticable.
I have to wait a few minutes, Plug and Unplug the Loop Jacks a few Times and then it works Like before.
Maybe you can help me out to find the mistake?
Otherwise i really Like how the Project went so far. In the past I have done some restorations to a Marshall 2204 from 1988 and a early Soldano Hot Rod 50 PLUS (which i still have.)
Please forgive me Language Mistakes, i am from Germany and so its a Little Challenge to Talk English.
Kind regards
Christian
