    the manual, troubleshooting & schematics are here:

    resistors & caps -, the quantities listed are more than you'll need, I wanted to have a few spares of each.

    you need 2 - 27 ohm 1/2w resistors for the diode/scr board i grabbed them here because I forgot to get them at mouser

    300amp clamp meter so you can follow the procedure to adjust the trimmers.

    10K pot- front panel curent control rheostat

    NTE5994 diodes for the diode/scr board

    NTE5545 SCR for the diode/scr board

    2n525 transistor

    2N4062 transistor

    2n2646 transistor

    2N3390 transistor

    MCR107 scr

    Kemet Axial Tantalum Capacitor 1uF 35V T310
    for some reason I cant see the parts list you put together would it be possible to get it from you? never mind i got it sorted out ty for this my friend.
