In this video I'll show you some tips to help repair audio equipment without the circuit schematic.
In this video I'll be repairing my Ensoniq SQ-R synth module from 1990.
I'll trace the fault and test and replace the components quickly and cheaply.
The main points:
*How I quickly narrow in on a circuit
*How I test capacitors
