One of the best product of Luxman in 60s year, output power is 30W/channel, very good working condition.
Amplifier was maintenance and technical check by OTOMON LAB to be sure that it is working perfectly. Sound is very very sweet and powerful. Tubes are very easily to be broken as shipping, generally, I dont include tube but if you need tube you have to promise that no claim and no return in any case.
You can search on internet about name OTOMON Lab to know about their maintenance service.
