Hey guys,
I have a quick question regarding the replacement of capactors in my MS- and M-series amps. Do I need to replace all the little bitty caps as well as the power supply/rail caps? I have read the threads in the FAQ/How-to section and see no mention of this. I'm trying to figure out what it's going to cost me to re-cap an MS-2125, an MS-275 and an M-100.
Thanks!

MS and M capacitor replacement
Re: MS and M capacitor replacement
i would just do the psu caps unless there is any signs of damage to the rest ie- film shrinkage and leaking or swelling. generally it's just the psu caps that need replacing but it wouldn't harm to swap them all out..

Re: MS and M capacitor replacement
Thanks. The caps in the M100 are definitely swelling, but no leakage. No leakage in the MS2125 either but I think the big caps are starting to swell. It's hard to tell since they have been covered with a PG sticker/blue plastic wrap.
What you mean by "film shrinkage"?

Re: MS and M capacitor replacement
Ever dive into a cold pool? That's shrinkage. 
The plastic film around the capacitor shrinks due to prolonged and/or excessive heat. Those look fine but I don't think they're original units for an M. They may have been done already.
Slide a cigarette paper under the cap and check for residue - leakage. It's a good insurance policy to replace them anyway.

These caps are in my MS2125. I've had it for at least 10 years. It looks like just a sticker on the top and some heat-shrink plastic around the body of the cap. I slid some paper under all the caps on all my PG amps, and none are leaking enough to dampen the paper. I did find a few drops of clear liquid around one cap, but couldn't find any more.
