Luxman suck face

Congrats!!

(... "SERVO" face! :deal: :rflmao:)



Yeah - I fixed it on my old RX-101, a couple tricks involved but pretty straightforward. Also, lubing up the gear mechanism helps to quiet it down as it may scream pretty loud once it's working again without some fresh gear lube.

Here's mine after I got it working:


I'd want one just for that feature LOL
 
Was this luxman's first wireless remote? It sure is square and kinda clunky. Wish I had the battery cover for mine but maybe I can fashion something that works well with scotch tape over it
 
I am listening to my RX-102 now which just picked up it's rotation duty. It's a very good sounding amp. It has the right tonal balance, tight speaker control, airiness, big sound stage, sharp image, smooth and fluid high, and sweetness....

Also have the KX-101 which is also a good sounding machine. I enjoyed the music it records and plays. But I don't have a a deck with 20KHz response to compare to.

Suck face on both units were broken when I first got them. The fix was to replace the belt and lube the gears. Also needed to replace a FM IC as it's not decoding the MPX.
 
Update on the big Lux:

I took it apart somewhat and though the suck ... er, servo face motor works, it doesn't have enough power to turn the cam once it feels resistance. I would imagine the belt is stretched? I didn't take that apart at all. And of course no phono. So while playing with the cam and motor and making sure the spring was in the right place, I must have done something because the phono kicked on. Actually heard a click. Someone said there's a relay attached to the servo face somewhere. There is, it's underneath the left side (as you face the receiver) of the servo face mechanism - opposite the motor and underneath the cam. I took a little hook pick tool and with the cam just before the tipping point to release the face forward, clicked it into position and the phono works.

Since I don't really care about the servo face feature and I really don't want to take the motor assembly apart at this time, I desoldered the two wires to the motor, stuck a large nut in the face mechanism to hold it in place and made sure the little relay was engaged. Works fine and the face is all the way back.

Took some more time this morning to clean out the crap under the hood again. This receiver was owned by a heavy smoker. After 10 or so minutes, whew boy, did it stink up the joint. Smelled like an old musty basement had a fight with a hot plate. Cleaned out a bunch of dust and grime from the boards I can get to and anywhere else I could reach. Played it again for about a half hour and I think I've got the smell issue at least mostly under control.
 
No kidding. Usually I have to put the amp/receiver on top of one of my 5 disc CD players. Not so here. Plus it's heavy as hell and most of it seems to be in the transformer.

That 90 watt receiver pretty much qualifies as a monster.
Good luck with the work.
 
Heavy; that is sure an understatement. I got a RX-103 last year, updating the caps is work out.
Mine was probably similar to yours, the motor spinning but no face suck action. Belt was all I needed.

And the sound is just impressive. Enjoy.

Thread resurrection! OK its over a year old so may not qualify, but just picked up the Luxman RX 103s baby brother, the similarly infamous “servo face” RX 101, circa 1983 40wpc sound crisp, clean and powerful - but of course the suck face is dead. Great cosmetics, and bought it with the idea to resurrect the ingenious engineers at Luxman‘s idea of “when you turn off your stereo - bass, treble, balance, loudness and volume shouldn’t be touched by (your kids) unauthorized hands”.

My question is this: any nude top off phots of this sucker in action? I know the motor sometimes doesn’t get enough juice and I have a replacement belt, just want to see it functioning in all its glory from inside.

Any help is appreciated, and certainly those that have mastered this please share your knowledge, thank you

Some photos for your viewing enjoyment - this sucker was surprisingly clean, and well built for 80s plastic. I like it now, but will love it when this servo motor is resurrected!
