Dave,

Have you given thought as to where you are going to get 50hz. power from? Here for line-lock 50hz. videotape machines, we have a 50hz. power source running at 220 volts. This is the only way to properly power certain machines that do not have a DC servo capstan and video drum (the capstan/drum is directly driven by the frequency of the AC mains).

Best Regards,

David Crosthwait

>>> *   Capable of handling fragile acetate-backed 1/4" open reel audio tape
>>> *   Has a minimum of three playback speeds: 3.75 ips, 7.5 ips, 15 ips
>>> (38.1 cm/s, 19.05 cm/s, 9.525 cm/s)
>>> *   Has quarter-track stereo and half-track stereo (NAB or DIN) heads
>>> *   Operates on 220V/50Hz power without the use of step-up transformers;
>>> switchable is okay
>>> *   Capable of handling reel sizes up to 10.5" (NAB or AEG DIN)
>>> *   Optional: switchable NAB/CCIR (IEC) EQ
>>> If you have any information, questions, or potential sources for
