ERR12V repair

Hi,

I'm just preparing to perform the ERR12V repair on my K3, and
notice that in the bag I was sent the pin connectors are
gold-plated but the replacement sockets are not. I thought the
idea of the change to was make the path gold to gold all the way
through... can anyone confirm if this is correct?

Thanks and 73,

See Eric's response:

Has anyone ever seen any documentation of approximate Serial Numbers or dates of manufacture that this mod applies to?

Re: ERR12V repair

Hello all:

I had this error during Field Day, so I'm very interested in modifying my K3/100 #2826. However, I'm not seeing this kit listed as one of the "mods". Wondering how to obtain it. Suggestions?

73,

It applies at least below s/n 1500 since both my K3s (s/n 622
and 1450) had the tin plate pins on both the KPA-3 and RF board.
1450 has been back to the factory, 622 is waiting for me to get
around to it.

According to this message:

http://www.mail-archive.com/elecraft@.../msg130495.html

Regarding the parts: "They will be supplied free of charge on request
(email "parts at elecraft dot com").
Regarding the date of manufacture: "I believe we've been shipping the
gold-plated connectors since sometime in 2009."

All,

Thanks for the responses to this. I've gone ahead and fitted the
parts.

I've also had a few queries off-list, so I thought I'd reply to
the original post with a summary for future reference.

o Firstly, the update is not listed on the mods page. The original
thread regarding it can be found here:
http://elecraft.365791.n2.nabble.com/Older-K3-100s-can-be-updated-to-avoid-possible-quot-ERR-12V-quot-problem-tt7284312.html#a7285353.

o To get the parts, drop a mail to parts@

o In terms of the vintage of affected kit, my K3 is #2847.

o I took some photos as I was going, and have posted my method
at http://clarkema.org/posts/2012-06/2012-06-08-k3-service.html.

I do feel that it would be helpful to have an entry for this on
the mods page, with proper instructions. I for one would be
extremely vexed if my K3 failed completely in some remote and
interesting spot because of a known fault that I could easily
have remedied before leaving home. It's all too easy to miss a
single thread on the reflector (assuming you even subscribe) but
I suspect most people check the mods list on a regular basis, and
certainly when planning a trip.

73,
