    Well s7e9h3n wants his unit back so I have to stop playing.

    I’m going to return it with the no argon charge so that s7e9h3n doesn’t get over cooled. The final charge is 123, 22, 23, 14. The captubes are:
    #1 = 81" x .055
    #2 = 90" x .042
    #3 = 90" x .042
    sub = 30" x .026
    evap = 72” x .031 x 2
    (one captube per head)
    Exp. tank= 30" x .026

    I did play so that I could see what I could get out of it. Here are the temps with the thing pushed and tweaked with argon and methane. Methane worked well.

    It’s the bomb!

    Load, Inlet, head, out, suc/dis
    0 w, -123c, -123c, -123c, 13/145
    50 w, -121c, -121c, -121c, 15/175
    100 w, -121c, -120c, -120c, 18/185
    150 w, -119c, -117c, -116c, 20/200
    200 w, 116c, -100c, - 112c, 23/225

    Now I’m hooked. Next project will be a ¼ to ½ H.P. shooting for -60 to -80 @ 150 watts. Comments ? Thoughts ? I know “show some pictures” I will. I raided my barn and here is what I found: some things to work with.
