I would spray some contact cleaner in the socket and see if that helps. You might have to use a small screwdriver to pry the tube up a little in order to get the cleaner in there. Use caution if you use a screwdriver. You don't want to break the tube or the socket.

Be careful, I have seen 1 radio that must have had a loose tube socket, because someone soldered the pin into the socket. I guess they were too lazy to replace it. I hope that is not the problem with your radio.

Have you tried to push up on it from under the chassis while wiggling it from the topside?? (while holding it from the base of course!) Never seen one sieze up that bad before!

Wow thanks for the advice from everyboddy, when I look under the chassis and I wiggle the tube I can see the the pins moving like it wants to be removed and I can pull the tube up about 1/4 of a inch and thats as far as it will go I can't figure it out. I don't want to break the tube socket.

From below, I would put a couple of drops of WD-40 on each pin and leave the set upside down so it penetrates. Then wiggle and wiggle.

Can you maybe spread open the socket contact with a scribe maybe between the pin and the contact to allow some extra space?? Kinda grasping for straws now......
Or, Must be a solder burr or something like that on one of those pins, maybe you can round down the tube pins with a pair of pliars just a little and then attempt to pull it out again! The fact that you can remove it some is a good sign.... The band selector switch is in your way too..isn't it? |

this happen one time to me, when I left a few tubes in while I replaced a couple of caps. a drop of solder fell on one of the tube pins in turn soldering the tube in the socket, soon as i put the iron on the pin the tube slid right out.

Glad to hear you got it out.. What a cool radio. You have any pictures of it by chance? I've got two Zenith consoles. One of them is a 39 with the same face your's has.

yes I can put some pics of it, however it is apart right now but I can put pics of the chassis and the console and parts, and yes this is a really neat old radio and this is the first Zenith chairside I have owned. I am very excited to get her up and running but it's going to take alot of work, but that's the labor of our love.

pictures of Zenith 7S342
As requested here are some pictures of the Zenith 7S342, I removed the chassis and the speaker from the console and that was not a easy task, does anybody know where I can get some parts for this such as, and I am sure what they are called but there was little plastic pieces that go next to the selector switches there is 12 all together but I do have one so I know what they look like, they apparently fall off very easy, and I am going to need the decales, I did find one site that does sell decales but not what I need.

Those plastic pieces that you need as well as the push-buttons are available as reproductions but I just can't remember where I've seen them!
But, two places to check would be Rock-Sea Enterprises and Old Time Replications. Old Times website is www.antiqueradioknobs.com and just google Rock-Sea Enterprises. |
