[Elecraft] K3 upgrades and Modifications Checklist

[Ted G7BQM]

I recently purchased K3 Ser No 104 and have done most of the hardware mods on this list.  However two items are listed as 'No Docs' and just wondered if anyone has details on:

!.  8 volt regulator filter capacitor E530174

2.  Power meter diode upgrade E560048 D36 & 37

Googling has not helped so far and I haven't been able to find out approximately when these mods were introduced and how important they are.

Any help before California wakes up would be much appreciated!
