Emerson 637A Restoration

Just pull the bottom solder tab down a bit slide a new contact from a similar socket in from the top and solder the tabs together under chassis. That is the least intrusive method.

I have to pull the tuner so it'll be a few days before I report back. Thx

I found the time tonight. I had an old Motorola chassis that had a similar tube socket. After robbing the socket, I cleaned off the solder on one of the pins, then I used some short needle nosed pliers to "flatten" the small indentation in the contact. I then used some small narrow duck bill pliers to push it up and out of the socket.

I then cleaned up the contact. Ready for the tuner.

I pulled the tuner and removed the turret. Lucky me. the #1 pin on the 6J6 was the easiest one to get too! I removed the solder and the resistor and jumper wire from the old contact.

I inserted the "new" contact and used a small flat 1/8 dia. pin punch and a small hammer to drive it home. It felt secure.

Then I rewired the contact with the jumper wire and resistor.

I then tried the tube in and out several times. Good to go!

Thanks to ElectronicM for the suggestion.

I reinstalled the tuner and now I have sound.

I then found a 12SN7GT bad. I had it listed as bad but installed it anyway! I replaced the tube and now I have HV!

I put in the 10BP4 CRT that I cleaned up and restored the DAG with Slip-plate.

A few tweaks on the back panel controls and here is what I have. The CRT works very well! Of course I'll have to take some time to align it and set it up.

I do have an annoying 60 cycle hum/buzz in the sound. After I align it if it is still there, then I'll look into it.

That chassis probably looks better than it did when it rolled off the line. Great work!
