Model 16X - Problem With Radio Reception
#5

Ron. Thanks for your thoughts on the electrolytic cans...very helpful. However, I have another complication with them that causes me confusion on the connections.

The 2 electrolytic cans were originally parts #87 and #88, #30-2014 condensers with values of 8mfd 500v on this chassis. In a later change noted on a service bulletin, part #87 was changed to #30-2067 with values of 10mfd 15v. The bulletin said that the connections remain the same as before. That is my problem. When I look at the bottom of 30-2014 there is 1 post on the side of the can and 1 center contact with a screw and nut on it...pretty straightforward when I put in the new cap with 2 wire leads going to 2 contacts. However, on the bottom of #30-2067 there are 3 contacts. 1 contact is the post on the side, but there are 2 contacts in the center...1 is silver in the very center, and the other is blue sitting a little off center towards the edge of the can. When I install the new cap I am unsure as to where to attach the two leads and which end is ground, or is there no ground at all?

Also I replaced 2 old paper caps part #30-4020 in another area of the chassis. They are green and about 1 1/2 inch long with a black stripe on 1 end. When I replaced them I assumed that the black stripe end was the lead to ground, similar to the markings on the newer ones I am using as replacements. Now that I am having the "no reception" problem I am wondering if that was a good assumption.

I appreciate any help you can offer on these 2 questions. As always, thanks for your thoughts and thanks to anyone else who can offer some help. Sonny
