Repair woes Luxman R-117 AKA What fresh sweet hell is this

[tyeeslayer]

So I got this for free with another purchase as a non-functioning unit.
When I tested it speaker relays were not kicking, and volume pot was kind of "grindy"
So lets replace relays and deoxit volume pot and all should be good right? WRONG!!
I noticed some one had been in this unit previously. Half the screws on the back were missing, no problem I have plenty of those. The old relays had previously been removed, opened up, cleaned and put pack in. Not a great solution.
I got the relays replaced no problem. I fired it up on a DBT and relays kick in. GREAT!!
Then as soon as I turn the volume up a quick burst of music then it kicks out. So I turn mt attention to that volume pot. Crap this thing is destroyed unknown goo had been sprayed in it and it was broken with bent contacts and broken bits.
A search for a replacement pot turned up nada.
So I guess I have to see if I can rebuild this one something I have never done before, but I guess that's how we learn.
Wish me luck.

I've been searching for other R-117 info when I ran across your post.
My volume pot needed a thorough double cleaning before it functioned properly. The first go round left a little scratchiness and the receiver just didn't sound as I expected from the reviews.
Cleaned it the second time and sound and performance was markedly improved.
When I say performance I mean that the relays were taking a long time to kick in and the unit was going into protection mode from time to time.

I wonder if that volume pot is more finicky than other brands..The condition of yours suggests the previous owner may have been having the same problem I was and got a little too heavy handed turning the shaft back and forth to clean it...and sprayed a ton of cleaner in it. One thing I noticed is the shaft will not turn smoothly as we expect a clean pot to turn, because it runs thru the Remote Controlled motor.

Anyway, how'd you make out with your repair?

The volume control of the 117 is a known Achilles heel, unfortunately.
@tyeeslayer hopefully you got the unit working.

My R117 is acting up, mainly on the left channel. There are a few other threads on the left side issues. I'm just trying to get more information on them before I try anything.

Yes, good to get more info but wouldn't it be nice to get info that pertains to the issues you are experiencing?

Use speaker B and let us know if the issues go away.
