Music Reference RM9 Mk.I schematic


2009-11-24 6:46 pm
Is there anyone who have the schematic for the RM9 Mk.I?
Made some new pcb for this one. Double sided and with 70um tracks. The silkscreen is marked with the resistor values I found on the old pcb but I`m not sure if they all were the original ones. Got 4 left so if anyone is interested I could sell for the actual cost.

I couldn't find the board I thought I had left, but I`m actually making a new and improved version. Its not been ordered yet cause I still have some details left to work on. It may take some time getting the board made cause this Covid 19 thing is effecting everything from manufacturing, shipping and custom service.
