AR 3A tweeter problem

Some pots can be rebuilt and some are too far gone. I used L-pads in my 4x's. It was my first restoration. If you want authentic pots the ones from Chris1this1 are worth a try. While you're in there be sure to replace the capacitor. You'll need one 20uF per speaker.

Thanks!

I'm not looking forward to it.  It was tough enough working through the 12" hole of the 3As.  Working through the relatively small hole of the 4x, yikes.

It's not that bad. The xo is very simple and some of the work can be done outside the box. Cut the leads off the wax capacitor but leave it in place.

The HiVi option seems very good to me.  I used to be able to hear 20 kHz on the test records, but not any more!

If that is the solution, I'll do it.  Thanks.

I would like to know what a good test record is for assessing my hearing please.

You can find free tests online. You need to use headphones.

I was actually referring to those old "test your stereo system" LPs.

If you're registered with 23 and me, they have a hearing test.
