Interior ^ Electronics
This cassette deck has power rail problems, the power design is incorrect, it should be upgraded.
Several parts is the power section should be exchanged, by the correct ones to get the design right.
The deck can be updated by placing extra capacitors in the power rail to get better power rail properties.
This power design problem is in almost all models in the 200 series of Luxman,
like the problems with the L200 series integrated amps, its clearly a matter of planned obsolecence.
The deck is easely adjustable for modern tape types and personal taste in recording.
The mechanics of the deck are just to standards, but not as well built as a Luxman K92.
Tape mechanics ^ Laufwerk.
Sound is very good for such simple and relatively cheap deck.
