Hello, I recently obtained a pretty battered up K222ESJ from Japan, repair has been difficult but it's almost done! This unit in particular seemed to be in a pretty questionable shape. The first part of the odyssey was finding a proper 100V adapter, since I didn't want to damage it, I found someone that sold a 100V one from Japan and integrated it into the deck itself, so it now looks like a suspiciously european device from the outside, it doesn't heat up or anything since it doesn't draw much current. Then I repaired the mechanism, which was easier than I thought it would be, it's now all lubed up and it works beautifully without any noise, I ended up keeping the original capstan belt, but I did replace the mode belt. I lubed everything up and replaced the pinch rollers with new ones, I then aligned the tape path using a chinese replica M300 gauge. After that, there seemed to be some electronics issues, my father took care of those, one of the channels was not working, so we looked at the usual suspects: Broken traces (there were a few) and failed capacitors (there were also a few). On a hilarious turn of events, one of the connectors for something was not even soldered in from the factory, a big WTF moment. Unfortunately even with those replaced the broken channel still refused to work, so I started to fear a rare head failure. Fortunately my father fought through it and found three major problems: - One of the potentiometers had broken down. - One of the encapsulated coils had also failed (it's been temporarily replaced with a 10 mhenry coil, until I find a suitable 18mh one). - The head opamp had failed. In the name of science, the head opamp was socketed and replaced with a tl082 instead of the original 5220, I am not sure if this is a good idea for a permanent replacement or if I should find a working 5220. Besides from the many issues, recording appears to work fine, now just to find the new coil and we can finally begin calibrating the various potentiometers
