Feeling I had nothing to lose, I did just that yesterday but used sili
glue to hold it all together. It was an interesting learning
experience. Unfortunately, it didn't help my problem but mine was
working; just not to my satisfaction.
It still works about the same so I ordered two new cartridges from
Mouser to see if it's me or the cartridge.
I had been wondering how age/time/humidity could have the slightest
effect on a quartz crystal millions of years old.
Turns out they are not quartz at all but Rochelle salt which, like all
salts, are very hygroscopic and turn to mush in time.
