Hi Russ, I have not read all the posts on the EPG and you might know this already and if so please ignore this and forgive me, but seems like I read that there was a question of how to evacuate and charge the system with argon. You can use what one would use to evacuate and charge an A/C unit [vacuum pump and refrigerant gauges]. Also I had a question on your VIC build, I have about 100 or so LED'S, green, red and yellow. I was wondering if they could be used on the VIC I want to build and if you knew of an inexpensive way to test their wavelength nm, I salvaged them off of old electronic boards as I also did to build my Lawton PWM circuit, all used electronic components, works great.  https://www.youtube.com/watch?v=jlgZK1Ydm_I , well there will be more questions to come, thanks..:D

Yes you did, sorry I was thinking that it didn't go through.
