Goodmorning everybody!

I am Bobby and I have been fool'n with electronics since I was a little kid. I think this place is a great way to spend some time! I am very pleased to find others with similar interests. I am in Florida now and I got a few old time TV's and stereos I am going to restore. Currently I am working on a project to serve senior citizens but I have extra time for this great hobby!
I love the info here on the rebuilding of those early round color tubes and the photos of stuff like the '64 NY fair and the many older sets. I hope to get to the next TV convention. I am still looking for the photos from the last one.
Soon I'll post a list of some NOS RCA parts I need to get rid of for shipping costs. Amoungst the many things I seem to have in common with you guys is that I am in need of more storage space!
This photo is of a RCA ctc-15 that I believe has had somewhat little usage judging by the amount of original tubes and lack of dust on the CRT and chassis. I think the flyback is an original RCA replacement because of the HV cage missing a screw from being removed at some point but seems to be running well and cool so far. I put new electrolytics in the main power supply and still have to get that special stuff to clean the controls etc. The CRT has a week red and blue gun from rejuvenate'n when it should not have been done(another long story) but I think it will produce a good picture whenever I get this vertical problem solved. I subbed the main electolytic near the 6GF7 (C4 50mfd) but no difference. It could be the 6GF7 but my tester is on the fritz and my gut says it is some resistor, so, I checked most of them and found a burnt(open) 1/2watt 150k that connects a tab of the vert height to a tab of the vert lin(R105). I was feeling good at that point telling a friend we would likely see a full picture but I was wrong! No big change but maybe the picture height went from like a half inch to 3/4". I can see snow or the broadcast signal so I do have a short picture but the photo may sort of look like lines. If I disconnect the yoke it goes to lines. I read somewhere here that someone had put a new vert output trans in a ctc-15 and I just hope I don't need one. I think it would be just a line if the trans was bad. I have started to check voltages but my extra digital meter only goes to 200vdc. My main RCA senior voltohmyst is also on the fritz.
It is exciting and frustrating to be so close to a full picture but so far as to wait to repair the test equipment to get it done! Meanwhile my living room may never be the same. I bet many of you can relate! LOL.
