Micro Seiki DDL-150

1 9 7 7 1977
1 9 7 9 1979

Despite the higher model number, the DDL-150 is 40,000¥ cheaper version of the DD-100 :

> same power-supply but without 78rpm speed,
> 6kg lighter base with 2x MDF / 1x lead plate,
> no integrated MA-505 with load switches,
> no C-150 reinforced dustcover,
> ceramic shaft base instead of teflon.

The motor and zinc alloy platter are however the same and the same optional side armbases could be used to use a second tonearm.

The later DDL-150Z is a limited edition version with a lighter & smaller platter (35cm / 4,5kg) made of diecast aluminium instead of zinc alloy.

The C-150 dustcover is an 8mm thick acryl item weighing 3,5kg (!) measuring 59,8 x 9,8 x 46cm with a reinforced back.
