Octal tube socket inverter

[tuyen]

Hi guys,

Hope you can advise. Im after what essentially is a octal tube socket saver but wired invertedly (ie. pin 1 on the bottom goes to pin 8 on top, pin 2 on bottom goes to 7 on top, etc.). Long story short, I soldered 5 octal tube sockets on the wrong side of a pcb and not really able to change them over so need these ‘inverters’ so it will work.

So wondering if anyone has seen anything that could work. Do the octal socket savers that I see are for sale online able to be taken apart easily, so I can rewire them? Or alternatively, the octal tube bases, what top piece could I be able to use that fits on top of it securely? I could wire it up that way.. sorry for being long winded! Bit desperate and frustrated at myself for not following build instructions properly 🙂

Cheers,
Tuyen

Get an octal plug base and a plain old octal socket that will fit into the open top of it. Run insulated wires down from each socket pin, and thread them through the hollow plug pins, and snug them up to seat the socket. bend each wire slightly as it exits each pin. Now solder the wires into the pins.

Voila.

Don't be too upset. Everyone's done something like this, once.

Don't you really see any chance to desolder these sockets, e.g. by using an air gun?


Best regards!

I agree, desoldering is the way to go.

Desoldering the sockets not possible, as it would mean swapping about 50 components (including heat sinks) that I am not prepared to do!

Thanks for the post enzo. That’s what I was thinking would be best approach. Will order the parts.

Success in electronics involves double-checking everything in my experience - tedious, but less tedious than the result of getting it wrong as can be seen here. If only there was a magic mirror machine to reflect the valvcs!!


I've seen tube extenders made by taking an old broken/worn-out valve, breaking off the base, wiring to a socket and gluing the assembly together.

Why? Just unsolder the sockets, and use wires to connect to chassis mounted sockets.

If you have the room, I agree with kodabmx. Chassis-mounted sockets won't put stress on the boards, and you can get bottom-mount versions that are very tidy looking.

If you want to make adapters, try these:
