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.

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.


Have you read his heresy opinions:

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