Krell kps 25 sc

His name is Ruben, his Audiogon name is serraniruben, try sending him a message, maybe he can help. But it's been 9 years !

What part is working ? It has 3 separate parts, drive, d/a converter and class a preamp. The dac is probably not working and if it is the 20 bit version will likely not work again, those dacs are almost impossible to locate. In the preamp section, the heat has most likely destroyed some of the capacitors, but that is easily fixed by any decent repair shop, remember to order the most heat resistant replacement capacitors. If the laser in the drive is not reading the CD, it can be replaced, the chinese started making that laser again, and it can be found on ebay. Sometimes the rubber belt driving the laser head get brittle and needs replacing, and the metal track the laser moves on definitely need lubrication with a thin mineral oil. All parts of the Kps 25sc can be connected separately if they work, you probably need a separate dac, the drive section is  a JVC pro drive, one of the best ever made. I’m using mine into a Yggdrasil dac these days.Good luck !

Normally the disc spins if the clamp is in place, even if the laser is not working properly it will try to read TOC. What happens if you try starting it with no clamp ? Does it say “no clamp” in the display ? There is a sensor connected to the lid mechanism and clamp sensor connected to the main board with a fragile cable and connectors, you have to carefully disconnect this before being able to remove the top section, maybe it is torn ? Go into the menu and find the auto play feature and set it to off so it is not depending on the lid sensor, you want it working manually!

Click on my user name, and send me a private message.  On the Krell : Go into the menu,by pressing “Menu” turn the volume dial until it says “Cover” then press menu again, and turn the volume dial again until it says “Off” ( it gives you the other options “auto” and “ auto play”) exit the menu function by pressing “ menu” 2 times. Now try if it will operate !

Probably laser, or/and servo control board problem, time for a specialist, my guy is in Sweden ! There is a good guy in Holland too.
If you want to try yourself, next step would be replacing the laser head, but it is really easy to mess up a new laser if you don't know what you are doing.

Maybe, try searching the net, i bought my lasers of a Argentinien guy here on Audiogon  9 years ago, and one from a vendor on ebay, but i don’t see any for sale at this moment. My ebay purchase history does not go far enough back to be helpful, sorry !

Congratulations ! I hope you like the sound, after all that work, personally i know how satisfying it is when that damned thing is working again !
