Hi, building up the mini tiouner but the caps C3,4,6,7 state they must be low ESR but the part numbers for Digi-key are not. Searched everywhere but cannot find 22u 50v caps with an ESR less than 1 ohm? Any suggestions?

In practice I don’t think it is that critical. I used standard electrolytics in my minitiouner and it works fine.

The regulators specify a low ESR but I would think anything reasonable would be fine. Just don't use 50 year old stuff from the junk box. I used the ones from Digikey.

Thanks guys. The digi-key ones are no longer available, hence the hunt. If the German ones don't arrive I have some similar and will drop those in.
