Cabinet input/jack plate

[olypen]

I have an issue with finding an input jack plate for a 412 guitar cab. I have one but it has been tinkered around with and i dont trust it with my tube amp because i dont know what the inmpedance is anyways i need to find a jack plate with all the stuff with it(wires, cuircuit board???) and i know that marshall and randall and all the brands dont just sell them because they have the serial#s on them. Anyone know what to do???

I've seen them @ tubes and more.

Try Antique radio supply if you're interested in the Marshall style jacks. I think they have both mono, and stereo.

YOu will most likely have to buy the jack plate, some jacks, and wire it yourself. If you want switching circuits and such, you will have to make them up or buy the boards from Marshall or Crate or whoever.

The fact they put serial numbers on those jack plates doesn;t mean you can;t buy them. The numbers are added, the plates are not made with them.

The impedance of the cab depends on the speakers inside, not the jack plate.

If the cab is functioning put a meter on it and find out the impedance of the cab. If I understand you correctly you don't need a new jackplate you just need to fix the one you have, or rewire it properly if necessary.

This is what i have

So i have a 412 cab that had celestion rocket somethings in it really crappy speakers and i replaced them with celestion classic lead 80s(16 ohm).
What i need to know is how i would go about getting a new jack and wiring it up and know what the impedance is...if that makes any sense. i am going to be getting a new tube head and just wanted to get my cab working correct and know what the impedance is so that i dont get that messed up.
So how do i go about the new jack setup for this 412 cab with 16ohm speakers???

Jack plates here.

With for 16ohm speakers the cab will be 4 ohms mono and two 8 ohm stereo sections.
