The mother and father of all C.D. units in terms of qualty

[Telecolor 3007]

There where 3 companies that in the early days made relaible C.D. players:
"Sony", "Philips" and "Hitachi".
But "Philips" made what I consider the best mechanism. Theyr machines where very simple - they made protototypes of cooler one, but never made into production,
trough all "Marantz" which back then was theyr company made nice one like the 'C.D. 84', which had big V.F.D. display, a row of over 20 track display, direct track selection,
but the 1st and 2nd mechanism where wow! 'C.D.M.' 0 and 1. Sheet metal and cast Zinc. I have a "Philips" C.D. 204 - wanted 100, 101, 202, but too pricy - my machine was around 80-100 $ cheaper then at other sellers. It haves that cast zinc block. Besides the look of that mechanism, the assambley is very good, since more then these at least 40 years old machines works. And I don't know what made the so good, but despite beeing slower then linear tracking machines, they are very good at reading C.D.'s.
Oh, "Marantz" C.D. 84 used also 'C.D.M.' 1, but Made in Japan. I wonder if they where as relaible as those one made in Holland. My machine is Made in Holland.
'C.D.M.' 3 was also of metal, but not very relaible.
I wonder how 'C.D.M.' 4/53 and 4 industrial, also made with metal where in terms of relaibilty.
