Thanks to a friend who helped me maintain my sanity while working on this project, I now have a COMPLETE and ACCURATE SCHEMATIC for the HAKKO 936 T/C Soldering Station.
You and I corresponded a year or two ago about this, but at that time I did not have the info.
Please send me your e-mail address and I will send the PDF of the schematic, and PCB layout to you immediately...!
