[Central-Electronics] 600L time delay

[Chris Farley]

Bob, 

C27 sees half-wave rectified line voltage through R23 and the diode they're denoting as "RLY B RECTIFIER".  This being the case, a traditional polarized wet electrolytic cap is perfectly fine :)
Have to admit, that schematic is kind of weird to follow.

C27 is the 500uF 50V can electrolytic in the 600L that is across the 
coil of the time delay relay.    Just wondering how modern electrolytics 
work in this application, since the cap sees raw AC.    That's probably 
what I used in my other amp but I'm not interested in pulling it out of 
the cabinet to look!
