Greetings,
i man wondering if anyone is familiar with the Fisher "Spacexpander" Spring Reverb Unit, and how to attach a potentiometer to it. The unit has a jack labeled "Control Cable Jack". i'm assuming that i could solder the potentiometer to a cord and run it into the jack and get flexability this way. i'm curious though, what connects to what as far as the 3 prongs on the potentiometer being soldered to ground and hot part of cord.

hmmmmm.
any reply is helpful...i give thanks.

you need the following ingredients <BR> <BR>- Stereo Headphone Jack plug <BR>- A 250KOhm Potentiometer &#40;250K is the figure I found in the user manual. When I measured the resistor on my own Spacexpander it was only 198K! Probably the resistor value shifted that far over the almost 40 years this unit is old now?&#41; <BR> <BR>- Use a 3 wire cable and connect as follows: <BR>the sliding contact of the potentiometer goes to the tip contact of your plug. The two other pins of the potentiometer are connected to the ring contacts of the plug. <BR> <BR>- The original Spacexpander control uses a potentiometer with an additional switch: If you pull-out the potentiometer knob, the sliding contact is shorted to the second ring of the plug. &#40;The one which is further away from the tip&#41; Thus the reverb is muted completely.

ok. the directions seem simple enough but, is it really that easy? does anyone have pictures of the finished product for viewing?
Is this a radio shack project or do i need to buy specific parts from niche electronics shops?

Yes it is that easy. For your enjoyment I just took three pics of the original pot. See below..

Hello to everyone!
I am new here, and writing cause i got a problem with my k-10.
I bought it off ebay in a pretty good condition.
Of course it had NO control potensiometer, so i ordered one from fisher.
Problem is, that they sent me only the knob...(i thought they were selling it together with the cable..)

SO

As i am not good at electronics at all, maybe someone here will be able to fix me a control cable for my k-10, if i provide him with the new potensiometer.? At a given price of course..

You can contact me at: goena88 at gmail dot com for that.

I d appreciate any help, cause my fisher is dead without it ;-(

thanks a lot
