[Boatanchors] Old Electrolytic capacitors

[Philip Atchley]

Hi,

Today I replaced the filter capacitors in the SP-600.  The ORIGINAL one had a 
date code of 8-52, same as the 1952 contract date on the receiver. 
Surprisingly enough, all three sections still checked good for leakage, 
capacitance AND power factor.  Of course the radio has played a lot of hours 
over the past week.

ONE peculiar thing about this capacitor,  It's a standard SP-600 triple 
20uF/450 Volt unit in a metal can.  On the can is drawn the three capacitors 
with a common Negative (which it is).  HOWEVER, from the common negative lead 
the drawing shows a resistor tied to ground (which I assume is the case). 
BUT, using the Ohmmeter I read infinity between the common negative post and 
the case.  ?Que Pasa?
