adding a wired remote volume switch

Can you take a photo of the bottom of the board.  Take it square with the board.    The power switch is the one with only 2 connections.  All of the audio adjustments have 3 connections.   I am pretty sure that the 2 sets of 3 connections directly toward the front of the control from the power connection is the left and right volume.  The picture will help me confirm this.

Not only 'thanks for the fast reply', but 'thanks for the fast RIGHT reply'! While I went ahead and posted the pic you requested to the end of that same album, given what you said I verified that the '2 connections' are off/on, and the next set of 3 (to the right in the pic) are the volume. But I am confused about the reading on those three. (Lets label them 1,2, and 3, top to bottom). When I check resistance between 2 and 3 it ranges from 4.5 ohms to 15.65k ohms. When I check between 1 and 2 its almost constant at 2.2 ohms. Does that make sense to you? Also, when shopping for a pot, what should I ask for?

Volume is on the other side of the power switch, there are 2 for volume, one set for left and the other set for right. Off/On is correct. Volume are the 2 sets to left of on off. Radio shack sells a 100K ohm stereo potentiometer, only problem is there is no on/off switch. They do sell a pot with on/off, only problem there is it is only one channel. 271-1732 is the part number for the stereo pot. Notice the 2 bottom connections of the 2 sets of connections are connected together. That is the ground connection. The connections directly above the jumped ones are the wiper of the pot. That is output of the pot. The top connections are left and right signal.

It would probably be easier to move the entire board and shaft. How far away are you needing to move it? Somewhere on your camera there is a picture of a flower. This is the macro function, it allows your camera to focus in an extreme close up situation. Try selecting that and take another pic just like the last one. I am having trouble seeing the traces on the left side of the board. Seriously, as long as you are not trying to move it several feet away, and you have somewhere you can mount the pot and circuit board, it will really be easy to move the entire setup.

First, I did use 'close-up'. But obviously my technique needed some work. I just went through that drill again and posted a much better shot. OK, now you are forcing me to be completely honest... I don't have the option of moving the original switch because I am in the process of mfgr'n a replica of the original radio head from a 30's vintage vehicle. You see, back then the big old clunky radio was mounted up against the firewall with a couple of mechanical inner/outer drive cables running up to a small radio head in the dash. The radio in question is a new mfgr unit with a manual tuner (so I can sinc the dial mechanically) . I am remoting the manual tuner and have that worked out. I also have the front/rear control worked out. But I cannot remote the original volume control because I would have to have the bigger, inner knob for the treble/bass control show, and that is not an option. Also, because the 'treble-bass' and 'balance control' are 'push to engage', the knob would stick out to far. Not acceptable. My ultimate desire is to have the radio head look as close as possible to original, but have the radio itself located in a hidden, but accessible location for adjustment of those seldom used controls. Just so's you know what I am talking about I have posted a photo of what I am doing. I have digitally remastered the original face, found a source for the the needle and lens, and have worked out how to reproduce the plate, and original knobs (not shown it photo). So now I am a whole lot less confused than when I started this thread but now I need to figure out how to isolate the on/off, volume control. It should have been obvious to me from the beginning that the orange and red were on/off (daaa) but I see now that it seems like there are (2) pair of red-black-white wires. Yet there are (5) circuits; (1) bass/treble (2) left/right (3) front/rear (4,5) volume. How do I isolate just those wires so the original switch (in its original location) controls everything but on/off, volume. And the remote switch just handles on/off; volume.

Do you understand parallel and series wiring configurations? I will draw you a picture tonight. All you need to do is parallel the new pot with the volume section of the old one. Same with the power. You will have to leave the volume level on the actual radio volume control set to a pretty high volume level, Either on/off will turn radio on. They will both have to be off to turn the radio off. Either volume control will adjust the volume level of the radio up to the volume level set on the other volume control. I hope you can find a stereo pot with an integrated power switch. It has been many years since the search, but we searched high and low for such a piece, no luck, but that was before the internet was available.

"Yes" to your first question. Thanks for taking the time to produce a drawing for me. I will be looking forward to seeing it.

You should use shielded cable to do this. The black wire is the shield of the cable. Radio Shack sells a suitable cable. Connect both shields to the radio and to both bottom connections of the potentiometer.
