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!

Audiofeil, changing caps is as easy as changing socks for me. My advice was wrong because of the word "rookie". I'm so accustomed to working on electronic equipment that my mind "automatically" takes care of a multitude of things that could go wrong. "If it ain't broke, but it ain't working right, that tells me to fix it". Not so for a rookie.

By the same token, people who have been in analog since "the gramaphone" will advise "rookies" to buy used TT, arm and cartridge without taking into consideration the complexities of setup.

All people who have been in audio "since forever" should take into consideration the experience level of the person they are advising.

Is there any need or upside to forming (initially applying voltage at particular levels and time) audio power caps?
I'm not sure at what point (volts/ampacity/design) forming is recommended but if the OP is going to be somewhat of a perfectionist about the caps I figured it was worth asking the group.

Jeff_jones,

There is no need to form new capacitors. When capacitors are unpowered for many years electrolyte eats out dielectric (aluminum oxide) lowering breakdown voltage. Such capacitor should be powered at the lower voltage, increasing it slowly for a day or two to rebuild dielectric (voltage presence builds up aluminum oxide).

Every 20 years right?

That aside, there is no valid reason to change caps based on the OP's information.

And one day you will no longer be a rookie orifice 10.

Be patient.
