I've cleaned the trimpots with DeoxIT and FaderLube, and will set the bias before I put the unit back into service. It will not get played again until then.

I have a Kenwood KA-5500 amp which I acquired about a month ago and rebuilt. It worked when it arrived, so I only replaced electrolytics in it as well as the bias trimpots which the AudioKarma guys recommend be replaced with 10-turn Bourns trimmers. I made darn sure the bias was set before it was put into service! And the 10-turn trimmers are a great idea. Setting the bias on that amp, even with 10-turn trimmers, isn't exactly an easy task.
