[vintagesynthrepair] K2000 outputs blown
2004-10-08 by laurent
Hello all, I just joined this board. I recently bought a Kurzweil K2000 and am experiencing strange problems. This Mix outputs are very low and the Headphone outs are very high, cliping at medium volume. A quick search on google revealed the following: "This was a common problem on early K2000's. Later units had a protection board installed (also available as a low cost upgrade for older systems). Problem, as I recall, was that static electricity or floating ground problems could blow the output transistors when pluggin/unplugging cables to the unit. There is a transistor on every output that mutes the output when you first turn on the keyboard. Static electricity can fry these. If you plug in an audio cable to the K2000, THEN plug that cable into an amp, chances are you will short the tip of the plug to the chassis of the amp. This will destroy the transistor. The remedy is to replace the transistor." I was wondering if there was any K2K owners on this list who would be familiar with this issue and how to fix it. Thanks in advance Laurent

Hi, Thanks. I have sent a mail to Kurzlist but haven't had any response so far. Laurent

Just one question(well, 2 actually). If the transistors are blown, can if check it somehow? Can I change them myslef? I have opened the synth and I think I can see those transistors next the the various outs. Rather small but I guess it's doable with a little care. What do you guys think? Thanks Laurent
