Tekker Posted December 4, 2009 Report Share Posted December 4, 2009 Can anyone recommend a replacement source for those old 16 ohm Polk Aetna pots? I managed to cleanup one pair, but the other's too far gone. I don't want to use L pads.Thanks,Bill Link to comment Share on other sites More sharing options...
Carlspeak Posted December 4, 2009 Report Share Posted December 4, 2009 There is no exact replacement in terms of construction. However, electronic parts suppliers like Newark do sell Ohmite 15 ohm, 25W rheostats that will provide the same performance. The only caveat is you will need to cover the wiper section as it is exposed - unlike the A/P rheostats. Covering it will keep the FG or PET out of that area and prevent 'dead spots' in the wiper action due to the insular nature of those stuffing fibers.Be prepared to spend some $ for new Ohmites. You may get lucky though and find some used, clean A/P posts on the net. Vintage AR on ebay offers a pot as well.You should also do a search on pots in the AR area. There's been much discussion about your plight in the past. Link to comment Share on other sites More sharing options...

JKent Posted December 4, 2009 Report Share Posted December 4, 2009 These are the ohmites. Heavy duty but as Carl pointed out you have to fabricate a shield to keep the fiberglass outhttp://www.classicspeakerpages.net/IP.Boar...9&hl=ohmite Link to comment Share on other sites More sharing options...
