The mod schematic I saw showed a tapped 3 meg pot along with some resistors and capacitors. That should be fine for any ceramic. If the input was updated to provide at least 1 meg Ohm load (higher is better) the fault falls on the cart itself
Many years ago when stereo ceramic carts were still considered contenders for hi-fi use, one of the major reviewing publications put the Sonotone 8T under test.
Their verdict was the two sides (L & R) were "two different cartridges" in one envelope.
Consistency has always been a problem with piezoelectric's. Now, with who-know-what quality control from foreign manufacturers the quality problem is likely worse.

I recently swapped out a defective Astatic cartridge with a Pfhansteil P51 on my personal 1015.
Since the swap the audio seems to have lost a lot of low end and sounds “tinny.”
Years ago when I restored it, I had added a Bill Bickers upgrade to the volume control box to improve the bass response.
Obviously I’d like it to sound like it did before the swap. _______________________________________________ Jukebox-list mailing list -- jukebox-list@lists.netlojix.com To unsubscribe send an email to jukebox-list-leave@lists.netlojix.com %(web_page_url)slistinfo%(cgiext)s/%(_internal_name)s Searchable Archives: http://jukebox.markmail.org/
