all the original tubes are easy enough to get , so I don't understand what they were trying to do .
What tube is subbed in there under the chassis the 12AU7 ?
What tube is disconnected ?
This might be the same tube as a original , but the tube socket cracked , so it got wired up under there rather than drilling out the rivets and properly .
The thing that we must take into consideration is that most likely when this TV was last "repaired" it was of little value , so you can expect to see these kinds of shortcuts every so often as alot of customers only wanted to spend a few bucks on the repair or get a new set .
Might be a pretty simple fix by reconnecting the wires on to a properly mounted socket .
Don't think you got a dud just because you didn't get a picture .
Those caps are about 60 years old , alot of sets are dead like that , and come back to life with just a recap .
Does there appear to be any burned parts ? resistors , caps , wiring ect....?

The tube under the chassis is a 12BH7, it looks pretty burnt up too.
Doesn't appear that any of the tubes are disconnected or missing.
Nothing looks to be burnt just very dusty, will examine closer.
I am not thinking that, I was thinking I wouldn't get a picture because of the strange repair/add on. So I didn't even attempted to plug it in. Once the stuff is put back to original I will try to power it up.

Here's an unmolested one from that link earlier in this thread.

Nope they are MIA. I seen that photo, I guess what I will do is take the laptop in the other room by the tv and start putting things back to where they should be. I am thinking this stuff was added in to connect the tv to some kind of accessory or radio or something.
