Kenwood Basic M2 Upgrade

Connect its power cord to a variac and slowly ramp up the AC voltage from 0 to 120 over half a day. This will allow the electrolytic caps to reform, particularly if the amp has been in storage.

Any particular model you suggest? What does reforming the caps do/mean?

Thanks.. actually just shipped it out to drmaudio.

+1 jasonbourne - I would have all electrolytic capacitors replaced with higher temp, 105C caps, before putting into service. You can specify this to whomever is doing the service!

Its probably not there yet.. What would that do?

105C capacitors almost always last longer in hi-fi equipment due to heat. Electronics fail mechanically first, primarily due to thermal cycling and vibration. High temp 105C, vs. 85C caps mean, they are built better during construction, and can handle higher temps. Well worth the extra money if you're planning to keep you equipment for a while... FYI if you look at the price difference between 85C caps and 105C caps, it's not much. But when manufactures build 1000's of components, it can save $$ which translates into profit. Also if your equipment fails, you will have to buy another, that also means $$. Just my 2¢.

I mentioned it to them.. thanks for the info.
