New/upgraded TC-7520 power supply?

Well that seems a very reasonable price.
Could you give a bit more detail about it Stan-its design in relation to the old one.
Would you like the old one back by the way (I hate waste)?

Have a look at this alternative:

A cheap linear jobby-anyone used this or any other linear regulated supply?

is that model a linear supply? presumably then they get the output voltage range by switching the transformer secondary, otherwise there would be a lot of dissipation across the regulator at low output?

I have the 1612 model and that one is a switching.

Here is another supplier who describes it as a linear supply:

What is wrong with you guys? You were just told that a regulated linear is not ideal for this DAC and the rest of the thread is speculation about some PS being Linear.

Anyway, I think I'm going to go with the PS from the guy who made the DAC. I mean it's 23 Euro. You can't do any better than that.

Finally someone who is on the ball and paying attention.

In the words of Stan himself:
'What it needs is a low ripple voltage and current. So far only off the shelf linear power supplies can produce those types of figures at a low price'.
No disrespect to Leo but when the designer makes a comment like that it seems reasonable to be to look at alternatives.

No worries, I just try and help, not trying to force things on people;)

Normally a linear is better but thats without it seeing large uf on its output, regs in linear regs don't like to see that:)

The TC-7520 uses a two stage power supply design that is unconventional, and is of my own invention.
I am not going to sit here arguing with people and picking at words. You have had my say, I produced the two parts of the TC-7520 power supply, I wrote about it on my site,and I leave it at that. If people wish to ignore my time and effort and want to go their own way, well that's their choice. Just don't expect me to take part on discussions or offer advise on such issues. You are on your own.

You are wasting your time Leo. A few posts from now and your words of wisdom would have been forgotten. It is the 2nd time you have mentioned this, and the first time was not even noticed:doh:.
