1979 GTE Sylvania GT Matic CX9164W chassis E24-3
Just got this set in a lot of 4. This one was a huge mess. Got it cleaned up but the plug is cut off at the end of the cord which isn't a problem but I'm hesitant on testing till I know more about the flyback on it. There is a small bulge on top with some cracking and one edge is warped a little. Will it hurt to try or should I replace that 1st? I've circled the areas.

You gotta work on the pix sizing ! Dont feel bad, I wouldnt know how to
do it either !! I would ask my sons but I would forget in a few days. Anyhows It looks like an in line jug. Thats good as the earlier GT matic / Super Set deltas had a VERY short life. If it were me I would just fire it up with a variac. You need to confirm the CRT is good BEFORE you put time & $$$ into it. Post some sized pix of the area also first. All I can see is what looks like a chunk out of the FBT. 73 Zeno LFOD ! |

Ok, I think I got it. Phone has a resizing option but I never had to use it.

The small thing in the first pix looks like a spark gap. 2nd pix
looks like a tripler that is cracked open & NFG. Dont run it. After the week end I will see if I have a manual & give more info. Zeno |

Those were made from about '75 until '80, when they were replaced by the E32 single-board chassis with an IHVT.
On your set, triplers were a high-failure part, as well as the filter capacitor and bad solder connections. I ran into a few bad yokes and a number of weak tubes on these. When they're right, they have a nice picture. I think the tripler on these is an NTE523A.

Also, what is the filter cap on this? May as well replace with the tripler.

One thing I learned on an SCR sweep RCA is if the breaker is tripping and you want to know if it's the trippler or not just unhook the flyback output from the trippler input and stick the lead in a jar so it won't arc. If the breaker won't trip like that the trippler is bad, if still trips you have other problems....
You can do the same test to check the trippler if the set isn't tripping the break, but isn't making HV... Only you want to monitor Boost voltage. If it's very low with the trippler and normal or high without the trippler loading it then the trippler is bad.

I have the console version of this TV, mine still works yet suprisingly enough but its missing the "lock" for the front panel that opens up for the user screen adjustments so the user screen adjustment door is open all the time, which is also where the speaker is so the audio doesn't sound very good because the cover isn't properly baffling the speaker.
