hi jeliman,

if U had interest pls sign up. I had one new design Teflon dielectric, non-magnetic materials, which employs a high conductivity, Rhodium plated bronze copper RCA & BNC sockets. Full body is also Rhodium plated non-magnetic bronze.

I can post one to U if U like to buy the two items. If U like I will good offer to U. But I hope also good offer to diyers for your products.

Is IT OK????

pls sign up.

You could offer cheaper alternatives to opa 627.They are good but overpriced compared to others.This should bring the price down considerably.eg AD 8610.
It could go down usd 50 then if i calculate correctly.

Can U told me where I can get USD 50 per set??
I understand OPA627 had over price. But It still better to OPA2604 or other chips. Do U really can provide this USD 50 excellent price??? If U can provide in this price, I will glad that more diyers can benefit lower price products.

(PCB & Parts from China) USD 35+ Postage from China to me ( USD 3.5 per set.+ posatge to diyers by EMS USD 30~35, All chips ( TDA1541a+ SAA7220P/B + 74HCXXXXX+ Op-amp) i USD 35.
Paypal charge to me USD 2~3. Packing charge. USD 1.5.

35+3.5+35+35+3+1.5=110~120 USD

How can I save more money. Pls let me know?????
