Luxman M-02 amplifier, the dumbest amplifier ever.

[wattsabundant]

One of my post retirement gigs is doing repairs (amplifiers/receivers) at Stereo Lab in Columbus Ohio. Although the facility is relatively large, consoles take up a lot of space so I usually pick up the unit, fix it at home and drop it off when it's done.

What's wrong with these photos? Image 0411 is the bottom of the amplifier. Image 0406 is the top. Note that the board and associated components are toasty.

I guess, heat rises. Poor engineering to have those components on the bottom side.

I prefer my boards on the rare side. those appear to be beyond "well done"

It seemed like a good idea at the time...

You are assuming Luxman had heat control engineers. From my experience, if they did he worked part time.

This is the same type layout as the Yamaha C-4 preamp. Has a few issues due to heat but nothing like the charred boards I have seen in Luxman gear.

I have one of these amps and they will win most beauty contests. The design is very similar to the HK and NAD amplifiers. Mine is not as toasty.
