Hi Mike
Thanks for the information. I surely can find BC550C (there wasn't any left at the store, they normally have them). I 'll post evaluations (subjective of course) when I finish it, soon I hope.

Hi Chris,

I will have 2 spare boards, and I have modified Eagle files, that enable to make artwork from gif images or so. I think we should ask Michael about his opinion, as this is his baby.

You guys tell me what you prefer.

Hi Pavel,
Thank you. Just PM me if you need anything. I have both RMAA 5.5 and normal (Leader) equipment to test the unit with. I'm still getting use to RMAA.

Hi Pavel,
What is the distance between the registration marks? That will help me scale the pattern.

Thanks Pavel - Chris

The distances between centres of the angle marks are

Carlos,

it was Michael who had designed it, I only added 1 resitor and changed dimensions .....

Tribute to Michael !

Well - I am interested in the result. The OLG -3dB point is about 30kHz, as I verified, this should be a good starting point for a good sound ..

destroyer X · 2005-10-07 2:37 pm

Yes, pretty boards, i could see that was Michael boards, but he did not shown parts

Applied over.... you complete the job...thank you, i think he will be gratefull to you too.

thanks.

Pretty boards!

Carlos

Aren't the canadians already metrics ?

Pavel, maybe you can use the exportfunction from eagle and create
bitmaps with let's say 300dpi, or for very nice printout with 600dpi ?
If Chris then prints it with the correct dpi...

Mike

anatech · 2005-10-07 2:59 pm

Hi Mike,
We went metric years ago. Good call.

I learned to drive in MPH, KPH doesn't mean much to me!! Measurements in meters or less certainly do. Thank goodness for Physics classes!

Anatech, it is great to have you here with us, you are experience in repair..goood!

All those brigth men here is great...i am feeling very happy!

And the board turns more pretty!

Carlos

Hi Carlos,
"Man can not live by repairs alone". My first love is design anyhow. It's easier watching the mistakes of others, 20/20 hindsight. Besides, I make more than my share of mistakes! I get a good laugh out of it.

destroyer X · 2005-10-07 3:08 pm

I am sorry to be talk deep true to you.

But i really apreciate you Chris.... a good guy!

regards,

Carlos

Michael,
they were made by export function from Eagle, at 150dpi, just for filesize. I can make them in higher resolution, if any request here.

PMA · 2005-10-07 4:01 pm

Higher resolution

Here it goes ..

Ah, my point was, if Chris prints them out with 150dpi he has the
correct dimensions, or open them in Photoshop with 150dpi...
That's all !

Hi Mike, Pavel,

I was able to print the foil diagram at 300DPI from photoshop with the correct dimensions. Thanks!
