Ah… it happened to me as well, that’s really irritating.  
I would not bother so much, use a wire to replace the broken part of the circuit and you are to go. Find what is supposed to be connected to what and that’s it.  
It won’t look pretty but that’s on the other side 😁

> Got it !! I am wondering if R11 was not the issue from the start. I connected with extra wires and it works great. No buzzing, no frequency cut-off, all good. Many thanks !!!
