spurte Todor om hode alternativer ifall det må byttes ( hold mitt utenfor diskusjonen)
There are several options:
A) standard Studer head - very good, life of about 6000 hours, 540 eur;
B) long life amorf. Studer - 10k hours, 660 eur;
C) same as A but a butterfly head, with only 0.75 mm track separation - (standard tr separ is 2mm, that is 1/3 of available tape width) wider tracks give you 2 dB S/N improvement, if the tape is recorded on btf heads. 660 eur.
D) as C but long life - 760 eur.
E) Custom made 15 ips long life head - 860 standard or 960 butterfly. The custom-15ips means that the head specs are tuned to give max performance in freq responce at 15 ips. So, the performance at other speeds will be reduced. In contrast, standard heads are made to perform at their best at the middle between the highest and second speed (between 30 and 15 - at 22 ips, or between 7.5 and 15 - at about 11 ips.
så hvilket velger jeg ev : Longlife og butterfly i alle fall men så....?
