JVC M-L10

Beautiful and bestselling amplifier with a ten-year production run.

Since transistors are current-amplifying devices, they are used as such in the M-L10 - but sans Gm Processors as in the P-L10.

The M-L10 is based on Victor's traditional Super-A circuit, in Power Cascode mode.
Keeping voltage constant but letting current vary allows to avoid phase problems as caused by loudspeakers' capacitance and inductance - the M-L10 can therefore drive as easily a real-life loudspeaker than it does the purely resistive loads of the test bench...

With Active Bias, cascode bootstrap and low-heat power transistors, Victor got itself a musical and cleanly powerful... besteller !
- see image #5 for the details and the Tech section for the complete description.


The transformer is a big, very big, enormous, Godzilla-esque, toroidal hidden under a two-part square metal casing ; to access the board under it, it easily slides to the back for complete removal

The main caps are four 80V / 10,000µF, probably ELNA For Audio.
The rest of the componentry was (as time has proven) refined but reliable : high-stability metal-film resistors, low-noise Zeners, silver-foil clad contacts and unetched capacitors.
Victor in Japan and JVC outside Japan however never cared to detail any of this more precisely.

At a time when Kenwood (L-08M) or Pioneer (C-Z1a) were trying sci-fi designs, Victor crafted magnificent enclosures made of real rosewood trims and 21 lacquering steps. And sold much more than the others put together.

Wise hi-fi of the discrete kind - Victor !
