I have a solartron 7075 volt and ohm meter,its mains input conector/filter smels like a cap is bad,still working but smells horrid,i have a mains input filter from an ols 2215 scope i broke up for bits,the mains filter i removed from that is marked corcom st40? can i just plug the mains cable into it and leave its ass end disconnected from a load to leave it powered for an hour to test if no caps are going to fry ie riffa etc?.its a bit of a pig to get at the nuts at the rear of the solarcon filter so only want to do it once,hence testing the replacement from the tek 21215 scope.
