新しいラックスマンDMLユニット 今すぐご利用いただけます。

Available now: new stock,

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.
Available NOW!

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.
