Rookie; replace my own amplifier caps??

Hi. I am mechanically oriented generally, and I have a knack for fixing things. I am decent with a soldering iron, and I understand the concept of "wicking" away old solder to replace a part. I love DIY projects. I have no, I say again no, training in electronics whatsoever, however. I am told that my 2001 Odyssey Audio Stratus Plus (120,000 uF capacitance) solid-state amp (I love it) likely needs cap replacements. I understand that "preventative" cap replacement is a hotly debated topic within itself; assume for my question the amp needs cap replacement. Is it likely that I could order a bucketload of Blackgate (or higher quality) caps of the correct values from PartsXpress and succesfully complete this project on my own? (Yes, I would unplug the amp) Thanks!

Hey Klipschking, you were the guy who started the other thread I mentioned. I suppose this thread is asking a different question as to whether you should be the Maytag repairman, but you ultimately have to answer the threshold question: do the caps NEED to be replaced?? Perhaps you already have answered the question in the affirmative.

Jeffrey is spot on. Get the whe amp assessed if there is a need. If no problems, leave it alone unless you want the upgrade.

If you want a DIY project then change the large electrolytic caps in the power supply. While it isn't technically challenging, it won't be cheap.
If I were you I would contact Klaus for advice. Maybe he'll make you a deal on the replacement caps.
FWIW, I would think the caps are still fine.

I agree with Jallen, that Jeffrey is spot on. I calculated from data provided by Nichicon on large electrolytic caps (I published it in different thread) that standard cap running in 35degC (95degF) has 80% of capacitance after 17.8 years. Long life or 105degC caps have much longer life. I would like to repeat what Jeffrey and Jallen said - don't have a cow, man - don't worry about it if it sounds good to you.

It's a piece of cake. If you know + from -, go for it. After 10 years is a good time for cap replacement. Caps don't always go bad, they just get sluggish and the amp loses definition.
