xrk971 Pocket Class A Headamp GB

Jump to Latest
#63
You really don't need to match BF862 for the Pocket Class A Headamp except fromstabfpont of channel balance for left and right. Not too hard to get Idss match within a few percent. I easily found two with Idss at 13.53 and 13.50 mA. At least nothing like matching 10 pairs on the other amp.

Lots of last minute interest here. We are getting close to 50 board limit which is what I have ordered already. So it will be based on whatever is remaining.

Funny how there is all this last minute interest yet the votes went from 5 to 3 average. Obviously there are a couple of putz's here who are party spoilers who can't leave well enough alone. I know who you are. 😉

Ordering Parts

Hi there,

I am excited about this project, but am a bit confused about the recommended shopping carts. I found two that needed to be purchased:

Ok I have triple checked the layout vs the schematic. All looks good and I am almost ready to order boards. However, the fab houses in China will not open until Feb 3 after the Lunar New Year celebrations are over. So I will leave GB open for a few more days. In the meantime, please send me a PM with your PayPal email and where you are located (Country). I will send you an invoice.

Thanks,
X

We are currently at 38 boards:



To make ordering the BOM easy, here is a Mouser shopping cart for everything except the SMT resistors, SMT caps, and battery terminals.

Here is the Digikey shopping cart with all the SMT resistors, bypass SMT caps, and 4 pin PCB and mating connectors with crimp pins. Enough parts for 2 amps plus lots of spares for resistors as they were most economical to order in qnty 100.

Have I missed something or is there something else that needs to be ordered?

Thanks for everyone's help.

Hi Zimmer64,
Sorry for the confusion. The first cart from Mouser had the main components minus the SMT resistors - which you can buy from Mouser or anywhere else. On the second shopping cart from Digikey, I am providing the SMT resistors and SMT 100nF bypass caps as an option, as the prices are much lower than Mouser (for just SMT resistors). I figured folks might want to buy 100 pieces of ea to save money. Mouser would charge you as much for qnty 5. Also included are the small JST 4 pin connector for the battery harness. This is optional as you can directly solder the wires on if you wished.

Hope that helps.
