Pedja Rogic 1541A DAC Custom-Wound Transformer European Union Group Purchase

jonclancy · 4th October 2004, 05:46 PM

Hi All,

those lucky enough to to soon be receiving one of Pedja's 1541A DAC pcbs might be interested in this GP. I have had a quote from Airlink Transformers for a custon-wound toroid for this DAC. I specified potting and banding. Hopefully dispatched to you direct from the factory.

Here is the info:

I am looking for a quote, please, on a specially wound toriodal
transformer. I have been part of a DIYAudio group purchase for some 1000 VA toroids about 9 months ago, and will hopefully be able to get 10 plus orders for this particular spec. The application is a high-quality Digital to Analogue converter and the windings are as such:

Transformer TR1 secondary windings

#nominal voltage current rating actual circuit requirement
1 7-9V 1A 20mA
2 7-9V 1A 13mA
3 7-9V 1.5A 27mA
4 7-9V 1.5A 37mA
5 21-22V 2A 40mA
6 17-18V 1.5A 15mA
7 17-18V 1.5A 15mA
8 7-9V 2A optional, for a reclocker

The 7-9V seconadries I would like to specify as 9V. The 21-22V as 22V, and the 17-18V as 18V.

In summary, five secondaries of 9V, two of 18V and one of 22V. I would require the toroid potted and banded as well, please.

No rush on this. I would appreciate if consideration be given to
dispatch to individuals ex-works. I will coordinate payment and
dispatch details.

Rgds

So, what do you think?? Can anyone improve on that?

Cheers

Do yourself a favour and stay clear of Airlink transformers. They have extrordinary bad service and a real bad relation to warranty issues and specs. As soon as you've paid, any problem that may occour....is your problem, they don't care. I fought them for several month over a couple of errors obviously made by them, which they didn't want to correct.

This is the general attitude of Airlink, not just one careless person.

There are other transformer manufacturers in the world, no reason to support a company that behaves like that.

Hi Magura,

I have PM'd you.

As ever, I am open to suggestions from anyone who has got a rock solid recommendation.

Cheers

Hi Jon

Just set you a PM to see how you got on sourcing the transformer. I'm in the UK and need one.

Dave

jonclancy · 31st January 2005, 09:36 AM

Dave,

you have mail.

Is there anyone else in the UK that is interested in a custom-wound trafo? I have been a bit tied up recently, so soucing this part has slipped below my horizon.

Cheers

My memory may fail me, but I don't recall a mail from you.

Jon,

not in the UK but also interested in one of those transformers,
or even two of them - (I'm trying to talk a friend into this project)

jonclancy · 1st February 2005, 12:45 PM

Hi Magura,

cast your mind back to 5th Oct.......

I haven't had them chase me to follow up the quote, mind you.

A decent supplier at the right price would be excellent. I'm more than happy to try another couple of local companies for quotes. With the GBP and Euro so strong against the USD, it might also benefit us to look further afield than the UK or EU. If anyone has any suggestions, please feel free to list them. I have emailed Plitron and VM and we'll see what they say.

I have also just had a spending moratorium strongly suggested by Mrs C, and I have agreed to it. Therefore my limit is somewhere around 50 Euros (slush money) for the trafo - unless I can do some window-cleaning on the side!!!

Cheers

Jon

Antrim have called me to confirm the spec and will be quoting in a few days - got 10 prototype orders in front of ours.

They will be more expensive than Airlink, but I believe the trafos will be quieter.

More as it comes.

Nice one Jon, keep us updated
My dac has been up and running for a few weeks, I'm currently using separate transformers but a single one would be better
I'm also struggling for a case, the dac and transformers are bolted to a piece of wood
