I recently purchased the Nelson Pass designed amp kit and have been able to proceed with the build quite nicely even though I am new to the game. I have reached the stage requiring the installation of the transistors and the MOSFET's. What precautions should I be taking in order to prevent damage from static electricity during the installation? How should I implement those precautions? Thanks in advance.

I would say from my place 'not at all'.
This is true because the relative humidity never goes below 80%.
You have to be careful if you get zapped from static discharge after rubbing your hands on certain things.

This may sound funny - but I spray a little water on my self , my clothes , surrounding(NOT the solder station or other similar sensitive stuff) with using common salon/garden variety spray to increase humidity levels & reduce static.

just 'brushing' your hair and body clothes with wetted hands may remove the worst 'accumulated' static
washing hands first may be a good idea in any case
and then avoid all kinds of plastic afterwards
Just keep hold of something grounded or make a lead that plugs into the mains with just an earth wire in the plug.
Try not to touch individual pins, rather grasp the device with all pins at the same time.

The Forum stated a long while back that the high capacitance of the gate Pin to everything else protected the Gate from excessive voltage.
This seems to have applied to all the high power mosFETs that I have handled, tested and installed. None has ever been damaged by static.
However, low power and very low power mosFETs do not have such high capacitance.
So far having worked with a few 500mW to 10W devices, I have not damaged any. Was it luck?
jFETS seem to be impervious to mis-handling.

cotton lab coat or clothes, antistatic work mat, antistatic wrist strap, best to play safe. Damage may not be instantly destructive, but can cause reduced life expectancy or problems later on.
Your clothes coming in contact with certain chair fabrics can also create static build up as well.
I have gotten into the habit of grounding myself whenever I sit back down in my work chair, before I touch anything else. If you have a grounding point close by, it is easy to do.
