Misc:

Superficially similar to the Philips N1502 both externally and internally. Very few components interchangeable between the two models however. Slower tape-speed and a slant-azimuth recording technique (to almost eliminate cross-talk between video tracks without using tape-wasting guard-bands) made possible the longer playing time without a noticeable loss in picture quality.
