I've got an old Altec Lansing ACS340 3.1 computer speaker setup that has begin to give me problems with the wiring. (Loose solder joints likely from having banged it around so much.)
I like the sound well enough to not want to upgrade to better speakers, so while I am tearing them apart to re-solder the connections I thought I would also re-build the cases out of hardwood to spice them up a bit.
I would like to replace the existing Volume/Bass/Treble pots with ones that I can put on nicer knobs, but am unsure as to if they are linear or audio pots.
I found a schematic for the system and it lists all three pots as 25k, but not whether they are linear or log pots.
Anyone care to venture a guess? Thinking the volume might be audio and the other 2 linear, but no real clue. Since the whole thing was marketed as cheap computer speakers for Dell computer decades ago I'm assuming that it's whatever pots were cheapest.
I'm guessing just measuring the resist. of the pots with a multimeter would answer my question right? Measure as I sweep the dial and see if the resistance changes linear or not?!?
It would be nice to already order the new pots and be ready to build before tearing apart the speakers to test as I don't have 'other' speakers to use while these are dissassembled.
Any guesses greatly appreciated!
Thanks!
