Hey Vid, thanks for the awesome guide! I am ordering parts to perform all these updates on my machine.
One quick question, you suggested removing the 27 ohm resistors and replacing them with jumper wire when replacing the TIP42 parts with MOSFETs. If I replace the 2N6122 parts on the row drive (Q47, Q49, Q51, Q53, Q55, Q57, Q59, Q61) circuit with MOSFETs (IRFZ34NPBF), can I replace the .4 ohm 3W resistor with a jumper? What about the 100 ohm 3W?
