Hello everyone, I after the above chip from 1990-95

Does anybody know of a UK distributor likely to have old stock?

Many thanks

Why bother?


** Spoken like a true electronics philistine.


DAC chip technology has moved on since then.


** Shame how all the audio devices that used that particular chip have not.

I agree.

Ask Meridian?

How do you know it is the DAC chip that is causing the problems?

Slainte,

Jim

If the chip is cooled it is okay - apply heat with soldering iron and
it starts....

I'd remake all the solder joints before changing the chip.

I'd agree. Might easily be a poor solder connection. So if you are keen to
keep using the original spec DAC then remaking the connections with care is
worth trying.

Slainte,

Jim

But is there a 'drop in' replacement he can use in his D600 speakers? For
all I know, there may be a fix using a newer DAC, which is why contacting
Meridian is worth a try.

And TBH I suspect replacing with a normal version of the DAC might actually
sound fine. :-) But I think it makes sense to try and restore to original
if possible if he wants to go on using the speakers.

Slainte,

Jim

I can get a TDA1541A easily enough. The silver crown will be a lot
harder and more expensive....

This bloke has some interesting information about the Philips DAC:

That's not "information", that's opinion, (and in my opinion he's nuts).

A lot of what he says is a truism (true of any good DAC), and the rest is
wild speculation.

I can see the desire to use a pin-compatible replacement if this is for
fixing up something that is broken.

**Typical American attitude. If it's broken, chuck it out, regardless of the
inherent quality of the device.

Have you read his heresy opinions:

I thought no.7 was interesting. Is he comparing performance sound
pressure waves with amplifier outputs?

Oh dear, "a little knowledge is a dangerous thing". He has that "little
knowledge" and thinks it equips him to produce a page like that!
