Restoring the monster (1000-ZXL)

This is my repaired “to as new condition” 1000-ZXL.
I welcome myself into the “I Restored a Nak-1000 ZXL and survived” hall of fame.

These are the faults I found:

  1. No meters.
  2. Bad dynamics on meter after PP caps replacement.
  3. Bad 400Hz tone (PP cap problem).
  4. No FF, REW or PLAY, because of idler tyre.
  5. High W&F, needed new belts.
  6. Worn pressure rollers / guides, out of alignment.
  7. Hardened grease, and oil spill all over mech.
  8. Damaged (chipped) erase head.

These are the repairs I had to make:


  1. Orange PP caps replaced in all boards.
  2. Troubleshoot meter dynamics: Bad CMOS Switch on Display board was replaced.
  3. Troubleshoot az. adjustment: Bad Flip-Flop on logic board replaced.
  4. Full electronic calibration
  5. Demagnetized Heads.


  1. Change idler tyre & belts.
  2. Clean old grease, re-lubricate.
  3. Fit new erase head, rollers, guides.
  4. Full mech. alignment.


  1. Wood cabinet sent for full restoration (no pics available yet).
