Luxman RX-102 receiver - "Suckface" Yes, Suckface..........

Recommended Posts

I had no idea what a 'Suckface' was before this.

An interesting nickname for an interesting unit.

I don't want to give it back.

 

Sounds really, really, nice.

 

New recap record - 122 off the buggers  :o

Resolder where needed, also did a full resolder of main amp and speaker selector boards

New speaker selector switches.

New speaker terminals.

Reset Bias (was very low 8mv vs the correct 14mv).

Reset dc offset, now 0.1mv.

 

Not much chit chat this time sorry.

Lots of pics though.

Enjoy.

Next 2 pics show why its nicknamed a 'suckface.

When its turned off the right side of the front panel sits flush with the main dials.

Turn it on, and the front panel 'sucks' back to allow access to the dials.

Bloody neat idea.

The actuator is a motor driven slide with a flywheel loaded spring return when turned off.

Front panel doesn't 'snap' back and forth, it slides either way in under 2 seconds.

Boards can then be fully removed for servicing.

Very nice to work on, all boards can be removed or worked on by removing a few screws then maneuvering that board out.

Messy 'lying down' caps made neater by using parts that actually fit the available space.

Mmmmmmm yummy flux clean up...

Undo 4 screws, front section swings out to allow full access to all the front boards.

Yum. "Gorilla snot". After two main caps were removed, and after the snot was scraped off and chemically cleaned.

I do have a heap more pics, but these should be enough to give you an idea of how much work some units can take.

And the awesome results that can be achieved ;)

Dunno. thats your choice. :D

 

It is such a unique design.

Apparently the original face servo failed previously and the owner ended up buying another second hand unit (interstate) to repair this one.

He also says he has not seen another one that actually has a working 'face'....

 

I openly admit, I do like the sound from luxmans. So I'm biased.

HA, ironic, I've never owned a luxman...............

Ohhhhhhhhhhh I see.

Hiding things from the wife for fear of premature castration.  :ph34r:

 

Being single I don't have that issue. Mind you that's a win lose sorta situation..

 

In that case,

anything over 10 years needs to be thought about.

anything over 15 years needs to be examined.

Are you referring to the amp or to a wife?

My run with the opposite sex has not been, good. (Last one was a private nurse that stole her patients medications for her own use)

So I'll leave that decision to the individual concerned..

Thank you. But young I aint.

Ohh so old.

No worries. I'm as much of an 'internals perv' as the next guy.

And some of these older units really do put the new stuff to shame. Not always in sound quality, but just in sheer style or form.

Bridget bardot may not be the best looking these days, but hell in her day, Phoooooooooooarrrrrr. :D

Since your in canberra, why not get onto skippy or pete mac. EDIT or Zaphod. Knew I'd forgotten someone. Sorry bout that.

Their in your neck o the woods.

And all I can say is, don't put it off.

Just cause it works today, doesn't mean it isn't getting damaged further.

 

This luxman had one channel intermittent. Caps. purely down to old leaking caps.

Nope. But that means very little these days.

 

Best I can suggest is starting a thread for it, maybe in amps or diy ? EDIT - ( I'm just thinking this way you can get far better answers directed at your particular unit for best results )

 

Do up a list of questions and observations.

 

That way everyone can throw in their thoughts and suggestions.

 

There are some very clever, well learned people here. And I am more than 100% that with all the knowledge we/they/them can walk you through anything that could come up:)

 

The 'crowd' is a force that can fix anything.
