afb, avs, t q, metering rods

Yeah, kinda like that one but the one I use has a bigger diameter magnifier than the one you posted.

Im getting ready to suck it up and buy a nice microscope so I can use that to see down to the bottom of these hotter plugs. I can make it display on my computer screen or the giant monitor I’m going to buy.
Now try it. I caint see what you posted either. lol
