Hi Bob

The Electrolytic Capacitors are in the Power Supply board KLM-480B. 
They can't be missed. Those are the biggest of the lot. From what I'm 
told, the value should be: 35V 2200uF (x2) + 16V 4700uF. What I ignore 
is which goes where (C11, C12, C13). 

Also, any ideas where I can get ahold of a bunch of Switching Diodes 
1S1555 (or equivalent) + 50V 0.68uF 85° Electrolytics Capacitors? At 
least 10 of each. Digi-key doesn't have any and I doubt Mouser does. 
I'd need them quite urgently.

Thanks in advance
