Features of This Unit

Design of using vacuum tubes for all 
amplification circuits

All the amplification circuits consist of vacuum tubes (ECC83S 
x 2 pieces, ECC82 x 2 pieces, and KT88 x 4 pieces) that are 
manufactured by JJ Electronic in Slovak Republic.

Necessary and sufficient rated output

The rated output of 25 W+25 W (at the load of 4, 8, and 
16 Ω) that enables necessary and sufficient sound volume in 
various speaker environments.

Output tube, KT88

KT88 manufactured by JJ Electronic in Slovak Republic is 
used in the push-pull structure as an output tube, which has 
the reputation of powerful and thick tone quality.

Parallelized first stage

The amplifier on the first stage has been parallelized and 
directly connected to the driver stage with a high S/N ratio 
and low-impedance transmission.

Triode connection

The proven Mullard type circuit (for the driver stage) has been 
equipped, and KT88, an output tube, has been used in a way 
of triode connection.

Impedance matching

Speaker terminals dedicated for 4, 8, and 16 Ω are equipped, 
which can be used according to the impedance of the speak-
ers to be used.

Old-time parts layout

This product has a parts layout inspired by the design of old-
time masterpiece, MQ60.

Monocoque chassis structure

This product features a monocoque chassis structure that is 
orthodox and has been proven.

OY-15 output transformer

The OY-15 output transformer contained in an aluminum die 
casting case has been revived in an original shape.

Large-capacity power transformer

An EI-type large-capacity power transformer is used to obtain 
persistent tone quality.

LUXMAN’s original block capacitor

LUXMAN's original large-sized block capacitor is used to 
supply stable power.

2-line input

There are two lines of inputs for input terminals; one is a 
variable input capable of sound volume adjustment, and the 
other is a direct input to bypass the volume.
