Power supplies / Re: SSR01 => unregulated DC input requirements
« Last post by kunlun121 on May 11, 2022, 02:18:26 PM »In the end I was happiest with a 100uF smoothing capacitor. That is not a typo. (Measured load was 40mA rather than simulated 18mA.) It leaves a significant ripple for the SSR01 to deal with, but with 10V headroom in unregulated DC input this was no problem to eliminate for the super regulator: there was no measurable AC on the SSR01 output. The turntable sounded better with each reduction of smoothing capacity. Lower than 100uF probably won't be useful but I may yet try 56uF so see what happens. The super regulator is a weird and wonderful device.
