Aria ADL-1 Analog Delay
(The Ken Multi, Monarch, etc. MDL-7 is the exact same model.)

This circuit board has a Cherry switch installed as an improvement to the nowadays fault-prone ALPS switches. Replacement procedure described here.

500K: Clock (turn fully clockwise for a few extra-milliseconds of delay time)
100K: Bias
20K: Feedback (very tame in stock condition, turn counter-clockwise to increase feedback and enable self-oscillation)
