You can get a cap checker quite reasonably on Amazon. Just be sure to discharge the cap manually with a shunt before you use it, or let the amp sit for quite a while (so the caps discharge that way). I forgot about that once & fried my first cap checker. (And I did have a shunt handy . . . I just forgot.)
Indicators of worn/bad capacitors?
I'm sure this topic has been addressed before, but perhaps I can ask again: What indicates capacitors are in need of replacement in a solid state amp? Specifically, my system seems a bit harsh/bright lately. Nothing else in my system has changed (LRS, VPI HW-19 with Mörch UP-4 arm/Sumiko BP#2, Mytek Brooklyn DAC+, Cambridge CXC CD-2, Classé Audio DR-9 with very few hours on it, various cables). Could that be an indicator of bad capacitors?
Thanks in advance,
