hi poynton ,

Take care, looks old version only had S1 only, no S2 or S1 with doube unless was selected for DA96 or 94 of marantz.

Many re-print I saw. although I directly order from taiwan cost USD 17 per one. stell looks like re-print.

thx

Hi.

Apparently, the seller was a Tech. Manager for Marantz and 'obtained' 2 of these chips for his own use on a double DAC project.

So he guarantees that they are correct !!!


Could be a bargain - on EBAY UK at the moment - look for TDA1541A

Hi Andy

I can give 100% guarantee of this chips authenticity. I realise what you mention regarding the S1 and double crown printing.

Between 1992 and 1998 I worked for Marantz UK as technical manager. I had involvement with the Special Edition (SE) models they were producing at the time, preparing the initial samples for review and supporting production.

If you recall the CD12/DA12 transport and separate D/A converter? A high-end unit. Ken Ishiwata (hope you've heard of him) devised an upgrade mod, one component of which was a double crown selected IC. I carried out all the work required as specified by Ken and it went off for review to Ken Kessler. Subsequently the mod was offered to existing owners of CD12/DA12 units. I carried out the first couple. I have two of these ICs which came from the same packaging tube as the ones we were fitting in this mod at the time. These were with Ken Ishiwatas blessing.

I always intended to build myself a double differential D/A based upon the CD94II output stage, but never quite got around to it.

I realise that this is a sought after device in double crown spec, didn't realise that someone might fake one... Please be assured that this is absolutely what it says it is.

Trust this explains its provenance.

Kind regards ...................................

I guess Philips perfected the process in 1989!

I Holland we say: "are you drawn from the toilet with force" to the person who is willing to pay those prices.

But on the other hand, at this very moment i am listening to a Non-os TDA1541A, and wonder how it could sound with a S1.

You can always buy one from me for 75 euro

Shipping included of course.
