Luxman MQ-80 1974

This is an interesting amplifier I found while researching a Mons Stereo Labs 6336A amplifier. There is no info about this amplifier so if you know anything please contact me. However here we have a Luxman MQ-80 utilizing the 6336A dual triode.

NEC 50CA10 Triode

The 50CA10 is a triode tube built for Luxman by NEC. It doesn't get much mention because originals are very rare. Fortunately Shuguang has started producing them again so I don't have to panic. I've been waiting for Thomas Mayer over at Vinyl Savor to write about them because I do not have very much information on them and his write ups are great. Don't expect any tube dissections here.
 There are only  two amplifiers that I have found that actually used this tube. One of them is the Luxman MQ60 which is a 30WPC Push Pull amp . Now that the Shuguang is manufacturing these tubes again I've seen several DIY amplifiers use them in SET and Push Pull amplifiers.
 Here are the well used and loved 50CA10s my Lux MQ60 uses. They will need to be replaced soon I'm sure.
Here is a pic of the replacement option from Shuguang via Leisure Audio.
 And the not in English Datasheets. 
Yes that is 50v .175a heaters.

Luxman MB3045

Here is a cool pair of Luxman amps. Push Pull triodes and good build quality. I think this are rated higher than my KMQ60's. There are beauties. I'd love to hear a pair even though I am going back down the single ended triode sound next.
 Luxman is called the McIntosh of Japan. It isn't hard to see why. They look incredible. I like them better nekid with no cages.

Luxman KMQ60 Stereo Tube Amplifier


Thank you my good friend Terry for the generous trade for this beautiful Luxman KMQ60 amplifier. I have been lamenting my lack of a good tube amp and this fits the bill.



Here are some pics. It is much heavier than I expected.


I really like the connectors on this amp. Why can't all vintage amps have connectors of this quality. I have a deep hatred of screw terminals even though they work just fine..

This amplifier uses the triode tube 50CA10. It is rare as Luxman designed the tube and not too many were produced. I will be on the hunt for backup tubes soon.
