re: L-510

What is the damping factor of this amp? It is not listed in the manual like with other amplifiers of his type.

Luxman L-510 instruction/owners manual

Thank you for this service manual.

I'm still looking for the instruction/owners manual of the L-510 or of its big brother (L-530) with no result until now. If someone possess one of them, it would be a great add to the site.

With regards.

re: L 510 owners manual

Hi Frank,

I'm a former Philips R&D manager original from Sweden. I have a L510 and a M1600 Luxman beside some mixers and Receivers. If you need some particular service advice pls feel free to ask me. I just served my Luxman 510 that losed one channel. Is not big deal to find components that match well the original ones and give same quality and performances.

Fairchils has a lor of good equivalents transistors that even exceed the quality of the obsolete components hand selected by Luxman engineers. The only think is to buy more components and select self before replacing.

best regards and thanks for the owners manual that I missed.

re: L 510 owners manual

... och vilken skulle du välja om du måste L510 eller M1600..
står själv i begrepp att göra det valet till ett par Quad Esl 57 med en känslighet på 93 och impedanse på 15

Med vänlig hälsning

re: L 510 owners manual

Hello Ion,

I need to service my L-530. I need to replace all the output stage transistors. Could you pass along those Fairchilds Partnumbers?


re: L 510 owners manual

Hi Ion,
Can you help me with substitution for transistors?
I'm happy to learn something new from other fan of Luxman.
By now I only change capacitors C506 & C507 in power section with new Nichicon-s Gold tune, 15000uF/80V.
btw, I have a L-510. Still not so sure that I clearly understand schematic of main amp.
A lot of current mirrors and current sinks there :-)
Anyway, I liked RIAA equalizer and sound of L-510.
Thanks a lot!

Best Regards!

Hi Kiril,
