I'll keep this simple. I'll state the tube and the readings will go from Pin 1 to the last pin sequentially. I won't give the pin number for clarity sake. I'll list the resistance readings as measured/should be. All were measured from chassis ground except where indicated otherwise.
12CA5: 96/68 0/480K 0/12 0/14 530K/480K 1100/1000 295/295
12DQ6: 0/0 12meg/22 0/0 192k/9k 1meg/1meg 500k/Tie Point 20/20 3/0 15/25 (Top Cap)
To me, the 260v C voltage isn't getting to the 12CA5...but I'm kinda lost! Any thoughts? I'll remeasure to be sure.
