1974 AS 120W RCA B&W Portable TV Repair

[JManX]

Hello everyone! This is my first post so bear with me. Also, let me know if I posted this in the wrong place so I can post it somewhere else.

So I recently found an old TV in my grandma's garage. I plugged it in and found that the only channel I could get was when the main dial was set to 0 and the lower fine-tuning dial was set to just below 28. But, all I could get was audio. I tried it with an antenna attached to the VHF leads and to the UHF leads. I still only got audio. Next, I took apart the TV and looked inside (I discharged the CRT safely) then noticed that a lot of the vacuum tubes and their inside bits looked pretty worn out (this TV had been used a lot). So I decided to take out all of the tubes. But, since I'm an idiot, I forgot to mark which tube went where, and some of them are different tubes but have the same sized socket. I went to a local surplus store and got replacement tubes (most likely never used) but I don't know which sockets to put them in. I have searched all over for schematics or something. There are 9 tubes all together. Any tips on if there is some sort of indication as to which tube goes where.

Thanks.

P.S. I have included a photo of the inside of the TV and where all of the tubes go.


EDIT: I found out that one tube is MISSING. There's 10 slots but I only pulled 9 tubes. The missing tube is a 4KT6 tube. On the schematic it says that it is a 1st PIX IF
