The orginal power supply... it breaks down by an load over 1,5A...but maybe only because of them dry electrolyt caps...

remarkable, in the left button corner - there is the shematic of the swell Pedal (aka volume)

directly bevore the main-out plug, there is  photo-resistor which driven by an 24V Light bulk, the light shines thru a whole  or better a stripe which get bigger when you press the pedal...> real analog!
