Well, I finally got my tombstone!
#12

The Motorola 51x17 got 24s to replace 20s, . . . . I believed that was close enough also,  although it has stopped playing properly in the last few days. One might wonder if the 25% extra capacitance taxed the rectifier, but I am still without a way of testing tubes here to find out which one has bit the dust.  We'll see....eventually.

  I'll get the 600 volt caps when I start re-capping the 610. I guess I'll  test the power transformer before purchasing anything though.  I hope I don't have another disappointment there, like with the 39-6.  I'm still trying to get an answer on whether anyone believes a radio will still operate with 1/2 a secondary open. 

I noticed that insulator on the one cap in the 39-6 also, and am slowly picking up on that negative bias-thing. It's an irritating anomaly of circuity design in these Philcos to me,
( among numerous others), but I guess that's just the way Philco decided to do that, instead of with another secondary voltage and rectifier  like I've seen in other circuits. I know how important negative bias is,.... I've seen output tube's plates light up like filaments without it. Icon_e_surprised
