The LUXMAN vintage audio website ®
replacement DML units now available.
We are proud to present to you the new DML units we made.
The Luxman DML units: DML-01 and DML-02 are often the cause of problems in vintage Luxman gear.
These old DML IC devices break down after some years as they have bad thermal properties
and do not meet the Luxman standards. You should replace them when you find some in your vintage Luxman.
Replacing was not easy in the past as there were no spare parts available.
Some fake DMLs were issued on some internet sites, but these were made primarely for the benefit of the sellers.
Also some were replaced by discrete parts giving problems and having bad thermal properties.
Now a completely new conception has been made by the famous DML engineer from the USA.
This design without compromise and without commercial means, you pay for what you get.
This is the only non-commercial ultimate solution on the world.
For the Luxman vintage gear owner this is the real thing. Take a look at the photos and be convinced.
All work done by the DML engineer and me is free of charge, you pay nothing for all our efforts and hard labour designing,
producing, testing these fine new DMLs, we do this for all Luxman vintage gear owners in the world,
all Luxman owners just pay for the DML's they order and the shipping to their address: nothing more.
These DMLs are professionally made in the USA meeting extreme specs and of highest quality
and only available through this Luxman Vintage Website.
The transistors used are matched and each DML is tested and meets the finest modern standards,
now you as Luxman owner can give your Luxman a new life, meeting even higher standards than the original Luxman design.
The DMLs shipped to you come with additional Mil. spec. 10 turn pots and with additional socket.
So you can use them with or without a socket and you can also replace the old potentiometers for better DC offset setting.
A DML installation manual in PDF format is downloadable from this website here below (under construction).
We take pride in designing and producing these fine new DML units for the Luxman Vintage audio gear owner.
The original DML-01, it breaks down and should be replaced..
Photos new DMLs:

Distortion less than 0.001%
Noise better than -110 dB
Drift substantially less than the original DML design.
Thermal range: storage -40 to +90 deg C. / use with guaranteed thermal specs -10 to +60 deg C.
Selected FETs and matched transistors and each DML is tested.
These are non encapsulated DML modules with selected dual FET and matched transistors for better thermal properties.
Additional Mil. spec. 10 turn DC offset pot and additional socket option.
Measured bandwidth up to 10 MHz.
These DML modules can be produced to your personal specifications with personal choice of parts at special price.
Each new DML is tested individually in a working Luxman.
Lifetime limited guarantee.
In my experience with several Luxman amplifiers our new DMLs are a true improvement:
the sound image is much more dynamic compared to the old DMLs,
its a joy to experience how well our new DMLs perform in real life situations,
try it and you will be amazed! Success guaranteed!
If you are not able to replace the DMLs yourself or cannot find a tech to do the job: contact us.
How to order:
These DML-01 and DML-02 are available for all Luxman owners at cost of the production of the product,
there is no profit involved, you only pay for what you get and additional is shipping and possible money transfer fees.
For all Luxman owners in the world, the prices in $ are:
The DML-01 cost $ 33 (excl. shipping and fees and local taxes), price per DML including pot and socket.
The DML-02 cost $ 38 (excl. shipping and fees and local taxes), price per DML including pot and socket.
For Luxman owners that want to pay in € the prices are:
The DML-01 cost € 33 (excluding shipping, bank fees and local taxes), price per DML including pot and socket.
The DML-02 cost € 38 (excluding shipping, bank fees and local taxes), price per DML including pot and socket.
If any offer to you is made for more than the price on this website, then it is not our product, it is counterfeit.
Be aware of the fact that in Luxman amplifiers there are usually 2 to 4 DMLs inside,
to keep L and R channels equal we recommend you replace the DMLs in couples: each one L and one R.

Note: Please download this document here on my website for free, there are other websites
like http://scribd.com the website of Scribd, Inc. where you can also download this document,
but there you have to pay for it, they do this without my approval or asking me, they stole
this document and I get nothing: no money for the sale of my intellectual property.
