Additional Details


The Dynacord was described by the maker as ‘professional-type dual speed recorder for rack or portable mounting’. Solenoid-activated pushbuttons allowed smooth transport through all functions without having to first stop the machine – separate spool motors allowed dynamic braking while a direct capstan drive gave a ± 0.2% speed accuracy.
Two amplifier units were available, the DP-100 Broadcast model and a slightly cheaper DS-10 Audiophile model (pictured).
The tape mechanism had three heads, two speeds (15 ips & 7½ ips or 7½  & 3¾ ips) and could accommodate 10½ ” reels.
Price when new was $395.50 for the DTM tape mechanism, $150 for the DP-100 Broadcast amplifier and $90 for the DS-10 Audiophile amplifier. The case was $40 extra.
