Sorry, I'll try again.
I got the anode cap off; no pop, so I was confused.
Totally separate problem is that the wire shown above appears to have come loose. I saw a similar wire that was connected to the "motherboard" (top of the 2nd picture), so I pulled it loose to see how it looked and see if I could find a similar connector elsewhere on the board. I couldn't.
Does that make more sense?
?
