Well, I got my Christmas present early-- I got my first color roundie
Yesterday, I got a call from the HI-FI dealer asking if I still wanted the set. He said he needed the room, and that I had to take it "as is" but for $100. I said, sure! Turns out that he just got another RCA roundie, also in a metal cabinet, but this one has the blond paint job. I saw it in the back of a freight elevator but I couldn't get close enough to ID it.
So, I was able to test the 21CYP22 before taking it and it woke right up with good emissions from all three guns
It came with many NOS tubes and the RCA service manual. So far, he has not found the back. It is now home sitting on my dining room table. Things look pretty good overall, but I did find one troubling thing: A large quantity of grayish-white goo has oozed out of the power transformer (see photos). It's weird, I've never seen this color substance come out of a PTX before. It's still quite runny, more like grease than tar. Anyone seen this before? Seller thinks it was stored in hot conditions at some point. So, one of the first things to check is the health of the transformer.
I'll pull the chassis this weekend and post some more photos soon. I'm glad that I waited him out!
