Luxman R-3055

Yes indeed... I enjoy listening to a Lux every day... Such a nice and sweet, seductive and smooth sound...
But not syrupy as can get with certain makes ala Marantz muffled.. the clarity and sizzle is still there in the music, never strident or harsh.
It has everything, but not too much, and lacks nothing sound-wise to these ears.
The phono stage's are often very good too.
 
I just restored an R-1040 which essentially shares the same amp board as the 1050 and the 3055 is far more alive and precise.
 
I got a 3055 and am restoring it as well. I had a few Panasonic FC and Nichicon UKU and installed them and ordered the rest of the needed caps from Mouser. In the mean time I took out the speaker connectors, cut a piece of rosewood and installed 5 way binding posts, I also installed 18ga OFC wire for the internal speaker wire. Larger wire should give more bass.
Binding Posts.jpg I also damped the chassis with Sorbothane. I will post more when I get the rest of the caps.
Many thanks to Jeff for his advice on this unit.
 
I used the list on the service manual to order some of the caps I was missing. There is a complete parts list.
 
I have all of the small caps in and am waiting for my filter caps from Canada. I did run into what may be a problem, cap #317 in the service manual says 16uf 16v for a value, I swear I pulled a 10uf from there (& that is what I installed). I check all of the cap values when done to make sure things are right and went to look in my bag of pulls - I did not see a 16uf cap. Jeff thinks it is a misprint. Has anyone else run into this conflict?
I did change the wires to the phono board to Kimber pure OFC cryo treated as you can see by the white and clear wires running to the board. I also damped the chassis and boards with Sorbothane (pink arrows). I have it on the underside as well.
All that is left as far as install goes are the filter caps which I will bypass with Mundorf SGO and to install 14ga AudioQuest wire for the power cable. I will post more photos when that stuff is done.

If anyone can verify the value of cap 317- that would be useful to us all, thanks- Nut
 
I had a funky thing going on with my unit in that the meters would show a tuned station but no sound would come out. I sent it to my buddy Randy at Out West Vintage and he fixed it. I just got it back minutes ago and WOW, everything sounds sooooo good. It is almost tube like and is the closest I have heard to that sound, which I love. I can't say enough good things about how this unit sounds for the small investment. BTW I did buy replacement filter caps but both of mine were good and within spec so I left them in... we are moving to Colo in a couple of weeks and I just don't have the time.
BTW- the value of cap 317 is wrong in the service manual- it should be 10uf

I am more than surprised by some earlier comments regarding the r-3055 as being a step down. It actually has better specs than the r-10xx series? I was expecting a Ho humm sound before powering it up. And boom, it’s sounds outstanding. There may be issues that need addressed if are less than impressed. Check your dc offsets and adjust bias to spec per the service manual and clean throughout. It has a live full and rich sound that has me wondering why I haven’t learned about Luxman sooner. I connected a dac to the aux inputs and ran through some tidal masters and it is beyond sweet.

I think it was a minor step down in build/parts quality from the previous R-10xx series due to the deteriorating entire audio market and the Japanese economy at the time. Luxman was always known for great receivers since the company began in 1925 but, I think the tuners in the R-30xx series were considered a further tecnological improvement over the earlier models. Alpine bought Luxman in 1984 ant he susequent quality declined and Luxman exited the US market in the late 1980's. Recently a new group of owners bought Luxman with the goal returning the brand to it's former glory and they are now back in the US market with very high end equipment.
