Are we any further forward on this yet Dave?

Do we have a donor transformer yet?

Hi Philip, all....

It would seem that the morite guy grabbed all he could but did not get HD3 output Tx design......

More info seems to have come to light and I will investigate this and let everyone know what the SP is ......

Yes! I have a brand new unsued one here to make more from!

Regards

Dave

WAD HD83 and WD HD3 output Tx's
Grandchain design No D8449. I believe that Graham Luscombe is the man you need to talk to about them. He is winding me 6 as I type.....

The HD83 mains was wound by Morite in Torroidal style. Grant Armstrong at Amethyst put me onto Frank at another company I think are called SP wound or something like that, who have the design for the mains.

I got Graham at Grandchain to wind me three uprated mains for a reasonable price into the bargain..... 165V@100mA and 3.15-0-315V@2A
So a bit extra juice if you need it. Filed under D9403. It's an E/I core type.

Shame I have to wait a couple of weeks but it should be worth it....

Just a quick update...

The Grandchain transformers have arrived, and are very very well put together. Delivery was way in advance of the agreed delivery date.
Overall very happy with the service and price I received. Gone to do a lash up now........

Sorry Phil, all...

It's only for completeness. And also to let everyone know what a bang up job that Grandchain did for me.....

Very very happy with their products.....
