Group order of LM4780 PCB boards

[digi01]

Hi gays,I have designed two LM4780 pcb projects.One is standard two channel stereo amps,one is in parallel.The boards size is 127mm x 72.5mm,double-sided pcb,single chip.
the prices of small batchs is $20 USD/1PCB,30 pieces boards.If more, prices can also be reduced.
this is parallel layout projects,the standard stereo projects with the size of the parallel similar,same boards.you can use it make a stereo amplifier.

anyone interested?

this is my WIKI page.

its too expensive for a such a small pcb
worth less than RMB 20(US 3) each

I'll take a few if the shipping to Singapore doesn't kill me...

[digi01]

for li_gangyi,
shipping to Singapore,no problems Do you like the standard or parallel? I can make to order 0.1% resistors for the parallel boards use.Who has better suggestion?

i just checked farnell's site. they do not have LM4780. :|

[li_gangyi]

hmm...then I guess you'll need to get them straight from national...

I like discussing more technological details even more, making this project more perfect. I have designed a 4780 of bridge mode again.
