Roland SH-101 – Power Switch Replacement

It is very common that the power switch in the Roland SH-101 becomes bad, which was also the case in my friend’s unit. This can cause various strange issues, the unit powers up as it should but when the button is touched various strange issues can occur. This can be resolved either by opening up the original switch and cleaning it or replace it with a new switch. In this case we decided to replace the switch with a new one.

The original switch is no longer possible to buy new. There is a suitable replacement available from some shops. I am not affiliated with any of these

The original switch has eight pins and the replacement one has six pins. This is not a problem as only four of the pins are used. The replacement switch should be mounted in the top six via holes closest to the power LED

    i can’t seem to adjust the bender board LFO Offset to 0v on my SH 101. Do you think this is caused by a bad power rail?

      Sorry for the really late reply here, didn’t get a notification from WordPress. Did you resolve this? It is a bit hard to say for me as it is very little information to go on and I am no expert. It’s always a good idea to check all the voltages (e.g. +5V, +15V, -15V etc) before doing any deeper troubleshooting though
