Vintage Luxman parts source?

[legal eagle]

I am looking for a "dual monolithic linear ic" (I believe the Luxman item # is DMLOI6Z0).

Luxman (in its current form) does not carry that part :tears:.

Does anybody know of a vintage Luxman source?

 

[dr*audio]

Sorry to be the bearer of bad news but there is no source for Luxman parts. That sounds like it could be a custom IC. If so the only option is to wire in a sub board with a replacement circuit, possibly as simple as an opamp. Do you have a schematic showing this part?

 

[legal eagle]

I do have a schematic for the amp, and I'll have to take a look and see what's there about that part. Guess I'll tell my tech what you said...:tears:

And you know what they do to the bearers of bad news...

 

[dr*audio]

If you can scan the schematic and post it or a link to it, I might be able to come up with something.

Does anybody know what parts the 5M20 amo share with other Luxman gear?

Or more to the point - does any other Lux gear use the "dual monolithic linear ic" ?

:scratch2:

I still don't think that part is bad. Did you ever get another tech to look at it?

I am gonna have another tech look it up next week, found a guy 'round here who knows his way around vintage gear - the only problem is that he is about an hour drive away, so it will take a while before I'll get to him. Actually, the reason i looked him up was your suggestion that I'll get a second opinion. Sounds like a good idea, literally.

However, i figured that in the meantime I'll get ready to the possibility that this part is actualy bad, and I might have to replace it. As there is a good chance Luxman used that part for more than one amp, well...

I have not seen that part anywhere else. I also researched it and could find no manufacturer who makes a front end for an audio amp in an IC. I had thought there may be a part that could be adapted.

You have one option for this part, a donor unit with a good part of the same model. A custom component you have here.

My thought exactly. Hoped Luxman perhaps used that part in another component :scratch2:

Dr*audio suggested my regular tech may erred in identifying the source of the humm and protection, so lets hope my tech erred...

I know it's an old thread, but I hope you held onto this equipment. There is a guy in the Netherlands that has replacements form the Luxman DLM made up from discrete parts. They are drop-in replacements. Very cool.

Yes, the DML-01 and DML-02 have been reverse engineered and are available from some sources. I have not read about any other DMLs from Luxman that have been replicated. The -01 and -02 are generally used in the preamps and power amps in the LRS and LSS lines.

 

[jdurbin1]

Very cool... do you know if they used them in the 5L15 as well, or was it just the 5M/5C models?

It's good to know that there are parts available. Might even buy some for spares, if the 5L15 uses 'em.

C-12, 5C50, 5M20/21 and 5L15 at least so yes the integrated amp has the DML in it.

Probably more, M-12 and B-12 I suspect, too.

 

[jdurbin1]

Got it, thanks. Just picked the 5L15 up from USPS this morning, can't wait to check it out.

[meewoo]

Haha, you outbid me on that one!
I would bid more if I haven't gotten one recently.:thmbsp:

 

[jdurbin1]

Needed something to match up with the 5T50 tuner I picked up here on BT!

John

5T50, the first digital tuner available. 5L15 one very nice sounding 80-watt integrated amp. I like LRS gear. Not that I own any. It was the main rig in the sound rooms back in the day.
