universal chip pre-amp project

[Atilla]

I would really like to try the ucp 0.2 for my preamp design. It'll be great if there's a way to get a board to give it a try.

digi01, is there some convenient way for you to send to Europe? Maybe some non insured, standard post letter? Light and anonymous should not be a big deal..

I think you can improve the printed board layout by putting ground to separate the opamp between 1234, 5678.
eliminate traces running across 1234,5678. Underneath the opamp.

Yes,i would like provide pcbs.i have sent the UCP_v0.1 cam file to the pcb house.

P.S.
for a completed design.i have no idea about the power supply part.i will try standard fix regulated psu or batteries.
i think DC detection,RF filtering is useful function too.thanks A.T.
i do not like dc servo,it is too technical,short of human interest.

Hi Zang,
what's the status of the first samples? I can't wait to test this out..
About PSU: any suggestion? What are you using to test this setup?
Maybe you have ideas on using also an "universal" preamp PSU...

I like the concept...a minimalist universal chip pre-amp. Yes, I'd like to give this a try. Digi01 I am pleased to report that I hit the buy button. I think shipping address is with my Pay-Pal details upon the payment. Thank you for designing this.

I have got the samplers last weekend.the first round shipment will be post in a couple of days
I have assembled one unit,look at the attached photos.
thanks for your suggestions about the "universal" preamp PSU.I use a bipolar +/- 12VDC voltage-regulator diode based PSU.I prefer the things going to simple.I will draw a sch file for you review.
