I powered the set up slowly and all seemed OK so I went for full power. I was really surprised to see a distorted image. A little control tweaking and I got a stable image Those relacement vertical transformers are working just fine

Barely any sound though


After a little investigation, I discovered a broken antenna lead. Fixing that helped a little.



Then, I tried rocking each tube in it's socket and, bingo!, a 6AL5 wasn't making good contact. Plenty of sound now


Next, I hooked up a better signal source. The picture is pretty good, but rather dim. Not surprising really for an original CRT.


I switched to a dead channel and I have vertical bars similar to the last set I restored with the same chassis. This time there's one pronounced stripe and several faint bars.
I'll do some troubleshooting over the weekend. All in all, a very successful first power up
