Hi
My friend designed two regulator with very small size. He is willing to offer PCB sample to member on diyaudio forum.

Dual regulator : SIZE: 82mm X 59mm
Positive regulator : SIZE: 65mm X 41mm
Supply voltage range : 5V -- 80V

here are the pics of the regulators:
dual

positive

This is the PCB:
dual

positive

Schematic:
dual

positive

The mounting on chassis:

each member from DIYAUDIO can ask for one sample PCB(dual or positive). Because the different voltage has different BOM, please tell me output voltage you need. Only 20pcs of samples for each reg.

Applyer only pays the registered airmail shipping fee 3.00USD.
My email address: coffin@diyzone.net

cheers

Hey coffin,

I'm very interested in the "female screw" in the "mounting on chassis" diagram.

Hi
Sorry for my English. Is that called "bolt"? in Taiwan we call it "hat for screw" or "female screw"......
No offend to any female.....

And had been revised.....

Hi Coffin,

PCB must be very cheap - you waste so much area by lying down RB caps?

How is performance of these regs?

Cheers,
greg

Yeah, I was getting a bit excited, sorry, I'm not interested in nuts.

hey Coffin,

I was only having a little joke, it is perfectly clear that a female screw is a nut. Sorry, I should have been a little more respectful.

Hi
The performance of the PCB is pretty good!
Very low noise, low impedance.
The sound is very neutral and transparent.

Actually, the dual mini reg PCB now is the second version(the first version is color green, 2nd is purple), it sells very hot in Taiwan and HongKong.
