Longplay33 Posted October 15, 2023 Report Share Posted October 15, 2023 Do I have to push in and turn the potentiometers on the back of the ar3a speaker to correctly adjust the sound. They feel spring loaded to me.. Quote Link to comment Share on other sites More sharing options...
jnolan5784 Posted October 15, 2023 Report Share Posted October 15, 2023 No, they are not spring loaded, the knob has a set screw that allows for them to be removed. Sometimes this set screw has loosened and the whole movement seems a bit "mushy". A tiny flat screwdriver can usually fix this. Quote Link to comment Share on other sites More sharing options...
RickB Posted October 16, 2023 Report Share Posted October 16, 2023 They also could be corroded-very normal on these. Are these new to you and have you downloaded the AR3a restoration guide. It should explain a lot of what is going on with the speakers. Quote Link to comment Share on other sites More sharing options...

At the very least the controls' wiping surfaces are tarnished resulting in intermittent contact. More likely, they are corroded. Roy Quote Link to comment Share on other sites More sharing options...
Longplay33 Posted October 19, 2023 Author Report Share Posted October 19, 2023 Thanks everybody , I just brought a pair of raw wood ar3a from a relative of the orginal owner. The serial numbers are 17,003 and 17,028. All the speakers look orginal except the grill cloths have been changed. They sound very nice to me and I was told classical was played through them. The only flaw I have found is when turning the pots on the rear the tweets and mids cut on and off as I turn them. I am able to get all the speakers to play at once and have left them there. I would like to change the grill cloths back to look original if anybody knows where I can purchase something very close looking. I have downloaded the restore document which appears to cover everything ! Thanks for all your support, it's a relief to have your backing.

RickB Posted October 20, 2023 Report Share Posted October 20, 2023 The recommended linen may not be available but there are others-www.123stitch.com-search for 18 count linen-off white. Some are pricey some are more reasonable. Quote Link to comment Share on other sites More sharing options...
Longplay33 Posted October 20, 2023 Author Report Share Posted October 20, 2023 Thanks, I'll check that site out Quote Link to comment Share on other sites More sharing options...
RickB Posted October 21, 2023 Report Share Posted October 21, 2023 Also yours might cleanup with Oxi and detergent-try that first-remember not to soak the grill material backing too much-check again the AR 3a restoration guide. Quote Link to comment Share on other sites More sharing options...
