[Jukebox-list] AMI F sound problems, or lack of

[Steve Wahl]

What cartridge do you have?  Re-reading your original post, I'm
thinking it sounds like a bad cartridge wire.

If not that, I second Aaron's vote for checking the crossover.  Mine
had the symptoms Aaron described (upper horn driver not working).

I recommend you check the output of the crossover with another speaker
or two, hooked up in place of the F's cabinet horn speakers.

Personally, I simply bypassed the crossover for a split second (hooked
the tweeter horn directly to the amp output), but that may have
contributed to the horn driver dying a year or two later, so I no
longer recommend that practce. :-(

In my case there was a bad capacitor (a non-polarized electrolytic if
I recall correctly).

Definately, if you try another amp (any home stereo receiver will do)
feeding the speaker, and another speaker fed by the AMI's amp, you'll
narrow down the problem.
