Rebuilding started on RCA Victor 6T74 from S Carolina.
 Hi, guys!! Thanks, again, to Polaraman for picking up my tv, and to my friend Huggy Bear for picking it up from Polaraman, and, delivering it to me. Well, I have it, and have started on the re building. To start, I have cleaned the chassis, front screen, mask, picture tube, and started on re capping it.Here is one view os underside of chassis a couple of weeks back.  It will take some time, but, I look forward to watching some of my old favorite shows on it.  Bill Cahill

Dang! My edidt failed. Now, I have to try again.
Here is another picture of set in early stages of chassis cleaning.  I have more caps in it now, and chassis is now totally clean. Bill Cahill

Hi Bill
Started rebuilding my 6T74 a few months ago. Have replaced all the caps except for the 1kv jobs in the damper circuit. Opened up the hv cans and mounted the filters inside. A member was kind enough to sell me a great 16GP4so when I got the caps installed and fired it up I had a black screen. I figured out that I was missing the ion trap. Once that was fixed it had a nice bright raster. After tinkering for a while got picture but poor horzonal lock. Did find a few bad resistors in the horz. circuit. Haven't had a chance to get back to as a friend gave me a Pilot Super Wasp to get working. Will get back to it in a few weeks. Terry

The mica caps in your horiz. osc., and the ones in video I F 's are likely culprits. I'd also make sure on the operating power supply voltage on 5U4. DC
It should be 370 volts there. On our increased line voltage, this set was wound for 117v AC, with set fully operational, voltage could be as high as 460 volts, which will shorten the life of your filters, ans several circuits. May I see pictures of your cabinet, both openned, and, closed, and see a picture of set on? If you need any help, let me know, and I can help you.... Bill Cahill

Just fired it up to take some pix and the width has gone down to about 5" wide down the center of the screen. Will do some troubleshooting and take pix later.
