......Many years ago I got a transformer custom built by a guy in the lane that leads to the station (sorry I don't remember the name). It was very well done. If you can find the shop, I heartily recommend him.
Most probably the name of the shop is "Tomson Transformers" just near the bridge after remote control shop.

u right sir
Suggest you visit the metal market where they sell metal sheets in retail , bare wires etc. They all seem to have thin copper sheets here. However the copper band is used only as an electrostatic shield. The inner non closed band between primary and secondary would effectively reduce noise coming in from the mains side. It will need to be connected to the ground scheme.
Do you guys really have so much trouble with noise on the mains ? Unless you are just trying to make the ultimate supply !

Finding coper sheet for belly band may not be easy...
Where are you located ? Copper sheet is a standard product. You can buy it from the metals market, or you can buy it from the guys who supply the motor/transformer rewinding industry.
I don't understand why people are having trouble buying copper sheet.

That is because every one is trying to find it in diyaudio.com . One has to hit
the road which I am going to do in a couple of weeks and then post here the
address, telephone of the retailer....

I am from Goa and I can get all the brands(in the world) of liquors only. Rest all is 100s of kms away.
Anyhow, I just showed an easy place to get a copper sheet. I don't need any. Thanks for the help anyway.

Surprise info: Finding the enamelled wire is also a nightmare here...

I will definitely shield transformers in this way in the future.

Thank you very much for your post. It is exactly the
time I am looking for SMD and was thinking of searching
in LR, already asked Visha who did not have. Thanks
again for the definite source.

Dear Masood,
I know you are looking for this for at least
two years now in this forum. I already told you before that
I use toner transfer method and have no idea about photo
resist method. You can ask Viki.
Best wishes
Roushon.
Many have tried ordinary thin paper as found in catalogues. Try some papers of different types. Who knows you might get lucky and we all can benefit from it.
You might need to touch up the gaps...try bow pen with enamel paint. Some prefer nail polish as it dries quickly.
