Chromopaper or technova is used on screen for screen printing, Even if some how you manage to stick this paper on copper clad board and develop it, how are you going to etch it, As i told earlier Chromopaper dissolves in water, and will be washed away while etching,

Untill 2009 I had faced problem regarding finding high quality components here in Kolkata.

Now a days the story is different. More and more high end parts are getting into market here.

Last month I ordered 2SK1058 which I have been searching for about 3 years here with only mission-failed return. Last month's report was different. I did get my 2SK1058s within 24 hours of ordering. GGoD these FETs are damn expensive, I usually get my IRF FETs for INR25/- max; but these hitachi devices took me INR160/- per device. But I know that they are expensive, the fun part was in watching the shopkeeper's face while he was delivering me the FETs. He said something like this- "Goodness sir these transistors are damn too much expensive... i have never stocked such a costly transistor in my shop ever... Are you sure these are the devices you look for?" I clearly got him, he was unable to see a reason for a mere average diyer like me to order those parts... it's fine, and it's changing. In future I hope more expensive and premium parts like the high end opamps from Burr-Brown or NSC or vacuum tubes like KT88/EL34 etc will be readily available here... within six months or so...

BTW, I also got my Nippon Chemicon audio grade caps last months with those FETs.

dear shan
how are u ,i also get these transistor rs250 /in mumbai at visha electronics last year when i was on tour do u have any pcb of tr 2sk1058 and2sj162.if have plz share with me.thanking u my old friend u shan.yours ever masood

@ masood.
I have 10 PCBs remaining and each priced @100/-. Contact me at audioampdiy@gmail.com if you want to buy.

I am also planning to make more LM3886 PCBs after this lot with simpler layout. (very few people uses the special audio application circuits and additional components).

I am also working on a Stereo LM1875/ TDA2050 PCB with power supply. Will post the PCB layout on my blog shortly.

Cheers to Indian DIY
