Working my way through a Philco 19 code 126 and noticed two discrepancies on sealed caps.
1. Cap labeled "4989W" indicated in the Philco workbench reference material as a .09mfd and 200ohm unit, is shown in the code 126 schematic (item 5) as a .09 and 300ohm package. On the code 121 it is shown as a .09 and 200ohm. Go with the 200 ohm?

2. Cap labeled "8174B" indicated in the Philco workbench reference material as a 700pf and .05mfd unit is shown in the code 126 and code 121 schematics (item 8) as a 700pf and .09mfd. Not certain which I should go with on this one. Any suggestions?

Sorry for the "funny face" on item 2, should be an 8 but keeps coming up that way!
Thanks for your help, Jerry

I'd go with the 200 ohm and the 700mmfd and .09/.1
With bypass caps always go larger.

As usual, thanks for the response Terry. Shall go with the .1 and 200 ohm.
