Hello all, I am chugging along on my Philco model 19H- code 128. I am looking at the expected voltage chart from the Rider volume page 4-18. The Control grid to Kathode should be 2.2VDC- I am getting -21VDC. I think this may be due to me re-stuffing the triple electrolytic cap, item number 29. This has a 2, 8, and 10 uF cap in it. I think I have the 8 and 10 uF caps in correct, but there are no polarity markings on the schematic, so I put them in as they logically made sense. However, I did not put in an electrolytic in place of the 2uF cap. I put in a mica with no polarity(or something of a similar material, what I had lying around). Does anyone have any experience re-stuffing this electrolytic cap, and if so, should the 2uF cap be electrolytic, and the polarities? Thanks for any help.
