My new old admiral tv!!

[Tube TV]

Looks like someone's done some handywork in there .
Why they would bother is another story ?
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....?
