I obtained this Luxman MQ70 tube amplifier. It is in an excellent cosmetic condition.
The reissue one probably looks much better than the original one.
It has newly designed output transformers and a new circuit design. The physical layout of the amplifier differs from the old one.
This is a very good designed amplifier and it looks very good.
When I switched it on, one of the power valves had a red anode.
The cause was a short circuit coupling capacitor. A lesson, always check and measure the
voltage on the coupling capacitors. There was no damage to the power valve.
Set the bias, DC and AC balance.
I used it with a Luxman CL35 preamplifier and the combination sounds good.
