I'm actually pretty impressed with this unit. I listened to it intermittently throughout the restore process. It's only like 13W/ Channel or so. After replacing the six 2sc458 and the main filter cap it started to come alive, but the kicker was the replacement of the carbon trimmers. The stock ones were poor quality, probably the flimsiest style I've seen. Both left and right channels had the bias dangerously floating all over the place. With the multi-turn added and the spec dialed in ,,,whooo it's on a whole nutha' level. I also love the fact that this 2002 has pre ins & outs, I think that got scrubbed with the 2002A if I'm not mistaken. A pretty cool feature to have in this price range. Edit: From a serviceability standpoint it's a straightforward job with the nifty inclusion of a removable bottom panel, unlike say a KA-3500 or the KA-1400G I did recently.
