Hello, I have an old Super Space Drum, and at at he power-inlet it says: 24V Ac 100mA but it doesnt have a transformer in it. Does this circuit actually work on 24 V Ac? When I connect a 9V Dc adaptor to it the LED lights up. Is there a way to be sure BEFORE I connect 24 Vac?

Those were originally made for the Canadian market.  They do require 24vac.

Thanks a lot. I bought a 24 Volts Ac-adapter but my unit doesnt work. Whats the most common problem with this pedal? I checked all solderings and all cables inside and they seemed OK.

Blown CA3094 chips perhaps?

Try Scruffie if he’s about.
