Hello Ram . Sorry you are having trouble finding parts in your country and travelling 137 miles !!! If you can not find mylar/polysterene then use mica capacitors . Ceramic discs are 20% or greater tolerance and may give you problems. If you need a single sided circuit board then use the best solderable breadboard you can find with multiple holes per pad . It will take me several hours to convert sprint layout two sided pcb to a single sided pcb  . It is sad some countries around the world sell a very very limited supply of good electronic parts . BUILD A PROTOTYPE ON THE BEST AVAILABLE BREADBOARD AND PARTS YOU CAN FIND !!! Then later you can upgrade to a permanent professional PCB circuit board . MAYBE some other members can help you also . Thunting.com is all about Teamwork !!! I know you will be successfull on this project . I will still try to get you a black and white single sided image but it will take time . Maybe someone else on this forum has made one already and will see this post !!!.........Best Regards........Eugene

Note: I am just wondering if going to a single sided board will create any noise problems/oscillations ?

Hello Everyone . Here is an excellent brief tutorial on Breadboards / Prototyping . It saves me a lot of picture posting and typing. Great
Also here is a photo of an excellent solderable perfboard made by Velleman and a link on where to buy it :

Best Regards........Eugene

Hello ram , housein . I will send you the pcb layout software today if I find your e-mail addresses. I do not have any XR71 pcb boards . If I decide to make some pcb boards it will be in the winter months when I am not working and I will let you know . For now you can both use a solderable breadboard for your project .........Regards......Eugene
