During the recap of my CX-1000 I encountered this very stiff and cement like glue which was used to glue on larger capacitors on the main board. It doesn't come off like the other older Yamaha brown glue, which is much softer. Normaly I use a sharp piece of wood which doesn't scratch the PCB, but this glue is too stiff / strong. I tried with a small screw driver and already scratched the PCB Does anybody has tips / experience in how to remove? Any help appreciated!
