AUDIO HEAD RELAPPING
HERE AT AMP SERVICES OUR HEAD RELAPPING
PROCESS IS ONE OF CARE AND PRECISION. WE CONSIDER OUR WORK TO BE THE FINEST
AVAILABLE TO THE RECORDING INDUSTRY AND OUR FINISHED PRODUCT TO BE A FORM OF ART IN WHICH
WE TAKE GREAT PRIDE.
Too frequently analog recording heads are replaced before their full
productivity is realized. Considering the expense of new replacement heads, it makes
sense to maximize the usefulness of your existing heads. Especially when this can be
done at a fraction of replacement cost and without sacraficing quality.
WE WILL RELAP ALL ANALOG AUDIO HEADS INCLUDING:
2" 24TK to 1/4" mono - cassette dup
heads - cart heads
film heads - audio stacks for video
- all metal & ferrite(glass)
 | THE PROBLEM : |
| |
| When new, recording heads have
a specific "radius" or "contour" to the crown (area where the tape contacts the head). As moving tape wears down the head, this radius, which plays a role in frequency
response, becomes flattened,outside tracks become more worn or "shallow" than
inside tracks, and the tape no longer contacts the head properly. |
THE SYMPTOMS :
The effects of this wear become evident to the operator
as:
1. LOSS OF
HIGH END- ESPECIALLY ON OUTSIDE TRACKS
2. SIGNAL
INSTABILITY
3. OVER-ALL
LOSS OF LEVEL
THE CURE:
Amp services will
perform a preliminary check of inductance, DCR, and measure the depth of wear on your
heads to determine the percentage of life remaining. If warranted, we will then very
precisely restore the contour and polish the heads to a mirror finish. Great care is
taken to continuously monitor this process, ensuring that the final.00025 of wear is
removed during the polishing process and that no material is removed unnecessarily,
thereby maximizing the productivity of each head. after relapping, your heads are
then mounted on their head assembly and a complete digital / optical alignment is
performed with respect to AZIMUTH, ZENITH, TRACK HEIGHT, GUIDE HEIGHT, WRAP,
and SCRUB.
A comprehensive lab report documenting
all incoming and outgoing electrical and mechanical specifications will accompany each
completed job.
