[Kenwood] TS590S power spike hardware modification

[Steef PA2A]

Hi,

Kenwood finally has a solution for the power spike that drives some amplifiers into protection. After this mod my TS590 is perfect now. DK5TX has put some measurements on his website www.5tx.de

This is the letter Kenwood has sent to its dealers.

It seems Kenwood has finally listened to the complaints from all over the world about the TS-590 ALC issues. The following information was originally posted at the beginning of April on the TS-590 Yahoo Groups.
  Attention all Kenwood Dealers,

  We understand that there are TS-590S owners that are still having problems with the ALC spike issue, even after a firmware upgrade lowered the spike. If you have a customer with an amp that is shutting off and going into standby please share this info with them. The radio must be sent to a Kenwood Service center for the modification, it takes approximately 1.5 hours to complete and takes several parts, it is not doable by the end user.

  There is no charge for this modification, in or out of warranty.
  Kenwood will pay the return shipping from the service center.
  The owner pays for shipping to the service center, and we take care of the rest!
  The U.S. service centers will be ready to perform the modification in late April.
  Serial number range: B09xxxxx to BC3xxxxx
  From SN B4100001 the modification has been applied.

  Thanks for your support.
