I encountered another difference this evening - R177 is 2700 in my set but 1800 on the Rider's schematic. However, the RCA service info that came with the set shows 2700. I also notice at the bottom of the page Rider's has W93530-20 while the RCA just has W93530. Both do show 150K for R150 though.


I've have been making progress in spite of the schematic confusion and have this section just about done. I'm surprised at all the cap brands - Aerovox, Cornel Dubilier (C-D), Sprague, Micamold, etc.
No way that electrolytic in the middle could be reformed since it's blown a gasket.


I assumed the cardboard cover was held on by a blob of tar and tried heating it. No luck so eventually I just torn it off and discovered some sort of varnish was used.
Oh well. I'll cut it open, restuff and fabricated a new tube from something.
