[Elecraft] K3 - Reliability: Oxidized PA Power Supply Pins Issue

[David and Dianne on Comcast]

Hi Everyone,

I have an early K3 #371 from Feb 2008.

I have done all the hardware mods. It has served 
me admirably to date without major issue.

I saw in an earlier post today on this thread 
stating the following, "The latest was the 
oxidized PA power supply pins issue."

I am not familiar with this issue and do not 
remember reading about it here or seeing anything 
on it on the Elecraft web site under K3 modifications.

Can anyone shed some light on this issue or point 
me to an earlier thread about it?

Have there been significant modifications to the 
early K3 PA's to warrant considering replacing it 
with a newer PA version?

Thanks in advance for any info.
