4 track record head with bracket mount. Glass head surfaces are in excellent condition. The problem on these designs is the glass ferrite head cracks open of internal wire and head's surfaces can corrode! I can re-polish the head. It's a very special process that costs $88 plus international shipping standard (see info below). Head re-lapping will not work on this. Replacements of heads is extremely difficult to match spec. The electronics are very special to the performance of record + play. It does not follow normal rules but it can work OK if unit is calibrated back to standard N.A.B calibration with Maxall or Ampex 456 tape. #9 condition (more possibly available from other parts machines contact us 617-926-8020 )
