Who exactly are these private vendors? Both Deang and JEM Performance are approved Klipsch service providers. Deang offered good advice regarding ESR testing of capacitors, and was providing sound direction for the OP. I don't see anything to criticize here, except that fewer and fewer truly knowledgeable people are left on this forum.

Eh, they'll probably be fine.

I was recalling Al's plot of the K-77M (red) vs the Alnico (black), but to be fair, the Alnico magnets may not have been up to snuff. Given that issue being a possibility when buying used, though, I'd still recommend the K-77M for Erivera.

You are correct, the K77M has the ceramic magnet, and it's response differs from the older alnico tweeters. You are on the right track looking for a k77M replacement, to preserve the proper voicing of your Khorns.

That's a great deal. Wish I lived nearby.

Even with a discount, that's a very big price discrepancy.

I have an early pair of Crites ct-125s. The bad, a couple of broken mounts (1 each). I need a torque wrench. They mount fine as-is. I bought a replacement horn from Bob (when I only needed one replacement), but never got around to replacing it. The finish is different, shinier. The good: Like I said, they mount up fine, and work perfectly. $100 plus ship.

It sounds like the input selector switch is bad. The sound you describe is what a turntable plugged into a line-level input would sound like. Turntables require RIAA equalization for proper tonal balance. Without it, your phono will be all treble, no bass. Just a guess, but I think the switch isn't changing the input from line to phono, so the line level input is always selected.

There's probably a metallic bit(s) that stuck to the magnet in the gap, causing the voice coil to rub against it. I doubt that the voice coil is out of alignment. Unfortunately, you'll have to remove the cone to clean the gap out. This will probably entail having to replace the surround.

If the speed is varying while playing (audibly slowing down), the pot's wiper or resistive element may be dirty. In MM's posted instructions above, I would add step 1.5: Run the adjustment for both 33 and 45 rpm back and forth, from end to end, several times. This will help clean the wiper and resistive track of dirt. Many potentiometers don't have a hard stop at the end of their adjustment, but will make a quiet click, so keep your ears open.

Fast or slow-blow?
