Considering you had the S/C for a while and know how it sounds, compared to how quiet it used to sound, I am sure you know what you are doing. S/C's all have "some" ticking hidden under that whine if you listen for it. You arent just listening too close now for it and that is all you are hearing because thats what you want to hear is it, heh? Every now and then, I will catch it in mine and suddenly it sounds 10X louder than it was before, but its just in my head. Once I stop thinking about it, its gone.

But, in any case, any info yo come up with on replacement parts for the S/C, share share share!!! I would love to stock up on whatever parts I can for it just have for a future rebuild, if I ever have to.
