i have just get a hold of a couple of kickass relays in a dirt cheap surplus shop, the same kind ericsson used in there AXE stations have im been tool so they will work quite a while...
But im a litle dubuious in hove to operate them....
there were elna 24 rotary switches..., use some kind of MUX and buffer it the relays is realy easy driven 5v 100mW
if i where to use som kind of microcontroller i could make the relays make different combinations of parralleld resistors and achive more than 24 steps....
does anybod know of any solution i can copy ;-) or have any ideas or advices??
