Model 29 Questions
#1

Gentleman

I have a Philco model 28 cabinet with a 29 chassis. Got the tech data from Chuck Schwark (nice big prints I can read) . Here is some info, most of the chassis looks undisturbed but the filter cap #64 shows to be a three stage 8,8,10 mf now what was in there were two 8's the 10 is missing, also the can itself is mounted on the top side but is insulated( paper wrap) from the clamp holding it in place. There is a lead from the cap case (under chassis) ground that goes to #57

Chuck has marked the polarity for me on the print so my questions are.

1 Could it work with out the 10? Has it been working?

2 In the print the polarity of the 10 the neg is tied to the neg of the two 8's and the pos of the 10 goes to the chassis. How does this work?

Want to understand what is going on electrically

Thanks Eric
