LUXMAN MQ36

Commentary

This is a stereo power amplifier developed by Lux as a complete form of a bulb-type OTL amplifier which had not been commercialized much by manufacturers until then.

MQ36 consists of 2 output tubes, 2 driver tubes and 1 pre-driver tube.
The output tube uses 6336A, a 3-pole tube originally developed for communication equipment, and the output of 25W + 25W (16 Ω) is obtained by thoroughly refining the circuit.

Two thermal relay tubes and relays are used as protective devices.

It is equipped with a check button, meter and regulator to check the operation so that it can be used with peace of mind at any time.
In addition, it is designed so that if any abnormality is found, it can be adjusted on the spot.
