Had to sort 3x XE6000 with the same issue a while back, amps had to go to Hungary and the entire repair process took over three months. At our expense. |

If the temp sensor is jumping around suggesting its hot when its not, this is an easy fix that can be done in the UK.
There is 1uf surface mount capacitor on the circuit board right next to a hole in the circuit board where the wires go to the temp sensor. Slight stresses on the board can cause the capacitor to fracture. We replaced them with a small tantalum bead capacitor (instead of surface mount) and they work fine. It take about 30 seconds to replace the capacitor, and about 30-40 mins to disassemble and reasssemble the amp as there are so many damn screws.

That seems to be a very common failure. I had 3 or 4 amps with the same problem.

i had 6 with the same issue.
good amps with out a doubt, but in this day and age the lack of on board dsp / digital inputs makes it very old fashioned.

I'm aware of two 'common' issues. 1. The 1uF capacitor on the temp sensor circuit. Fails due to mechanical stress on PCB. I'm told this has been/will be resolved on all future amplifiers as they are aware of the problem. 2. Soft start resistors. Not sure if this was a batch issue, but we had a number of amplifiers with failed soft start resistors. Replace with recommended alternative and problem solved. Apart from the above 2 issues, which are in reality very simple fixes, and can be done by anyone with reasonable soldering skills, I can only recall one faulty PKN amplifier which has had to go back to Hungary for repair - I believe it may have been a faulty user nore than a faulty amplifier though.

I have one that is possessed. Developed all sort of problems. PSU blow up as last issue.
All the rest are fine beside some that had that temperature sensor capacitor replaced.

are these temp etc faults on xe or xd or both?
i had 2 xd2500 separately fail for the same reason a few years ago.. symptom was the amp appeared dead, nothing happened on power on. irish supplier at the time (sol) was super helpful and got them dealt with quickly. the explanation i was given was some smt caps broken due to physical stress on the board.. haven't had an issue since then (5 years maybe?) and have used the amps many many times since. |

Yeah both have the same problem.

Ive seen amps with much, much worse problems happening much, much more often. All in all, the issues I have experienced with PKN are very minor, and although irritating, they are not that serious.
The temp sensor capacitor they are aware of, so Im sure this will get engineered out if it hasnt already been.

I reported it to them around 3 years back, that's quite a long time to fix such a minor issue.
No UK distribution either at the time and they wouldn't even entertain us doing the fix ourselves. |

They are great amps. i can not complain a single bit. But their support is not so great.
They are not willing to send me the schematics for the PSU. They dont understand that customers very often dont want to send the amp 1500km away to be serviced and wait 3 months to get it back.
