Studio Reference Amplifier

[prasi]

Hi, all the Wimas come from a German distributor (www.reichelt.de), where I buy the most components. They are not very expensive and the shop also ship internationally. But I do not know the shipping costs to India, but they are listed on the webpage (also in English).

regards Olaf

Thanks Olaf for the information. I did check the site and for India, default shipping is 22EUROS. Way above my budget!. Ok, I will keep looking for a cheaper alternative.
Like I had said before, i enjoy your builds and nice that you test every design before you post files... hats off!!

Hi, thanks.
I couldt not see any oscillations while testing. Also the Zobel was always cold.

Hi Olaf,
what are comparison of sound of SR100 and SR60?... just asking as you have built both of them...

Hi Olaf,

Oh, oh! I have built the SR100 over 2 years ago and the modules were never installed in a complete amplifier. The time has never been enough and there were so many new ones to test. Forgive me, but it's not really possible without to hear the SR100 again .
It may be that they are more comparable.

Sorry again and regards
Olaf

dirtypcb can not work with sprint files and i have not knowledge to change- mess.

 

[olafk]

Gerber?

 

[Bangla H]

yes please, if possible- my dumb problem- how to do?- only basics in eagle.

 

[olafk]

Hi, here are the Gerber files. I hope everything is okay. I have little experience with it. No guarantee. Maybe someone can look at this in a Gerber-Viewer.

 

[Bangla H]

Thanks Olaf, will try it.
My Gerber- Viewer is going to anywhere ?- not to find- hmmm... scratch had.
Have done- and not converted to eagle- i wish i know a little bit more- have to learn!

 

[olafk]

Hi, if it goes wrong, I'll etch a pair of PCB's for you.

 

[Bangla H]

Hi,
kikipcb i've tried- no answer yet and dirty seems that it not worked.
Thank you for generously offer- have to wait a bit.
If the order was successfully i will give other members with spare boards build SR60.

 

[Bangla H]

Hi Olaf,
Gerber works, order placed- now its time to relax, wait and cup of tea or something.
