who makes a good PCB mount 9 pin socket?

I have need of a replacement socket in my Knight KP-50. Any suggestions on where I can obtain a good quality one without breaking the bank? Whats in there now are your typical cheap crap wafer sockets.

I can't tell you for sure but I usually scour ebay when looking for things like these..
 
If it's a power tube, I'd probably use a ceramic one, even though the modern ones aren't that good (there's Deoxit for that...). For a preamp tubes, I have some old stock plastic ones. What's the pin circle (measure across opposite pins)?
 
I've been using Belton sockets, they have thicker metal and grip the pins tight. Almost all ceramic sockets are China made and quality is fair to poor.

NEVER EVER USE GOLD PLATED SOCKETS! The gold plating is very thin and delaminates causing all kinds of noises, poor connections etc.
 
I have an old PC chassis around here someplace that has Amphenols, IIRC on it, if you want to go used, but decent quality... Altho, you probably have some also!
 
Check eBay. I saw several vendors selling NOS USA manufactured. Read the listing carefully and see where the seller is located!
 
I have a Heathkit board with a few decent 9-pin sockets that's yours if you'd like used.

The Beltons are OK, but that one is a chassis mount. This guy solders directly to the board.


Curiously, the two phono sockets are not original. The originals are a nice phenolic socket, possibly an Amphenol with a grounding finger for the shield but not 100% on that. The two phono sockets are mismatched cheapo wafer sockets with no finger, so there is a wire ground soldered from the circuit board to the tube shield. Why on earth someone would change them out to that, I have no idea. Its unfortunate because the only trace damage on the board is around those sockets. They have been awkwardly patched, and will need further work whenever I change them.

I de-oxited the BS out of them and scrubbed the pins and contact points and I have both channels working now. I'd still like to change them, ideally to ones that match the originals.


I'll see if I can turn up some NOS ones. I just hope I'm not looking for some unobtanium socket with an oddball pin circle or something. I can make do without the ground finger if i have to.
 
I'd sort of prefer to stay new. These have been replaced once already and the traces are not in good shape. If I do this, I'd like to be sure it never has to be done again because it may not survive it.

Ah, I see the pcb one now. That one isn't quite the same as the original type. Mine have the center post in the tube socket, which is used for a ground and for some support. Given the crap condition of the traces, I'd like to go with a socket that has that center post to get as much support as I can get.


Too bad nobody makes a new board for this thing. I'd love to have a fresh one to work with.
