Finjima Posted April 4, 2017 Report Share Posted April 4, 2017 I have not see these before nor mentioned here as a option for replacement pots. http://www.ebay.com/itm/25W-15-OHM-Wirewound-Rheostat-Potentiometer-25-WATTS-/262880483677?hash=item3d34e5d95d:g:iW0AAOSwI-BWKRAH seller has them in different wattages 25/50/100/200 but I only seen the 25 watt and the 200 watt (was wondering about the 50 watter too) listed at this time same price as the L-pads and no need to mod the cross over. *note to those who are about keeping original, do not panic! 90% of the time it is only important to keep it original at a time of sale. the rest of the time its the pursue of sound. unless it isn't and this prevents you from sleeping at night knowing you have something that's not original in your whole house. in that case try to be polite here. there are noob's present ** I would rather have a set of original AR stats in very good condition, that do not degrade the sound and performance of the speaker There may come a time soon when these pots become a valid option in the repair of my AR-3's I would like to hear from a number of people, including those willing to give these try also Link to comment Share on other sites More sharing options...
Carlspeak Posted April 4, 2017 Report Share Posted April 4, 2017 You can buy 4 of those (delivered) for less than the current price of one similar Ohmite rheostats of which the Chinese rheostats appear to be a copy. Will someone step up and buy a couple who has a DMM to check them out? Of course, consistent quality will always be in question. It's good to know though, the Ohmite's are made in Mexico.

stupidhead Posted April 4, 2017 Report Share Posted April 4, 2017 looks like a good alternate, but still should "house" them as they are wide open backs. Link to comment Share on other sites More sharing options...
Carlspeak Posted April 4, 2017 Report Share Posted April 4, 2017 I started out 'housing' Ohmite rheostats in 3-sided wooden boxes with a top. Eventually simplified to stapling a piece of porous fabric over them. Link to comment Share on other sites More sharing options...
genek Posted April 4, 2017 Report Share Posted April 4, 2017 The person who owned my 3a's before me had a rather...unique...approach to keeping the stuffing out of his replacement level controls. Link to comment Share on other sites More sharing options...
Finjima Posted April 4, 2017 Author Report Share Posted April 4, 2017 I hope you saved that, It would make a good test bed for Rheostat testing Link to comment Share on other sites More sharing options...
Carlspeak Posted April 4, 2017 Report Share Posted April 4, 2017 Those outboard L-pads are as sealed up as the original A/E pots. The original owner needn't worry about the stuffing. Link to comment Share on other sites More sharing options...
genek Posted April 5, 2017 Report Share Posted April 5, 2017 No, they're gone. I installed a nice, clean set of early AP units from an old AR-2a with windings and wipers potted in lithium grease. Link to comment Share on other sites More sharing options...
lARrybody Posted April 6, 2017 Report Share Posted April 6, 2017 I would like to see the comparison between these and the Ohmite's. As far as the 25 watt 15 ohm rheostats, it looks like there are only one available. How different would the 25 watt 20 ohm versions be when used in the same application? There appears to be many of those available. Link to comment Share on other sites More sharing options...

There appears to be many of those available. Here's another option. Search ebay for "Set 2x PPB-15G 15 Ohms 15 Watt Ceramic Wire Wound Potentiometer". I bought a set and will report back on them when they arrive. Looks like the shafts are very long but cutting them down should be no problem. They're Russian pots from a Bulgarian seller. Not 25w like the Ohmite or Chinese pots, but as Roy pointed out to me, the L-pads many of us use are "only" 15w and there have been no problems with them. -Kent Link to comment Share on other sites More sharing options...
genek Posted April 9, 2017 Report Share Posted April 9, 2017 There's currently some 15 ohm 25 W sealed back Ohmites on tedss.com. Pricey at $129 each. https://www.tedss.com/2022003170 Link to comment Share on other sites More sharing options...
ra.ra Posted April 10, 2017 Report Share Posted April 10, 2017 7 hours ago, JKent said: They're Russian pots from a Bulgarian seller Those look pretty nice and robust - - - and hopefully will work well after you test with some measurements. For trimming the shafts, try to find John's (xmas111) posts about using very similar eastern Euro pots in one of his AR rehab projects. The biggest challenge I can see is whether the diameter of these will be small enough to fit side-by-side within the existing spacing of vintage AR's that accept two pots.

lARrybody Posted April 10, 2017 Report Share Posted April 10, 2017 Bought eight of these last year for around $30.00 apiece. Used four in some AR3a's. I am now down to four. Currently these are going for $45.00 to $50.00 each. They are getting way too expensive. Link to comment Share on other sites More sharing options...
Finjima Posted April 10, 2017 Author Report Share Posted April 10, 2017 Those Bulgarian pots do look impressive and are a even better deal, way better build quality just by pics alone.(compared to the Chinese ones) I'm not getting the high price for the omites, these mil spec or something?

ramjet Posted April 13, 2017 Report Share Posted April 13, 2017 I bought four of the rheostats from Bulgaria on eBay (Russian MIL Spec apparently) and used them in my recent restoration of my AR2ax speakers. As noted by others they are open and do need to be covered ( I stapled cloth over the crossovers before re-installing the insulation fiberglass). The shafts are a little longer than the original rheostats by about 1/4" but this is a small penalty considering their low price and the fact that they work quite well.

They came today. 12 days from Bulgaria--not bad. They're just a tad bigger than the A-P pots, smaller than L-pads, so no problem there. Shafts appear to be steel and will have to be cut. I paid $19 including shipping for 2 pair (4 pots) but it looks like the price has gone up a bit. Still not bad IMHO Link to comment Share on other sites More sharing options...
