I don't see the inductor listed for the REF design, only the NIGCWIPS.

I believe even for the NIGCWIPS the inductor is optional(might have to change the value of the output resistor as Mauro states here.

You know, I saw it in the pic at the beginning of the GB thread, and just assumed it was there. I guess not. No problem then.

Brian, After looking for a while it seems everything is as it should be with the BOM and schematic from post #58 of the "REF" thread. I was just having a serious brain fart.

Cheers,
Russ

Can you describe the smell of a brainfart to me?

Perhaps you can post a ***.WAV that we can play over the amp to compare our sonic impressions.

It is great work that you are doing guys!!!

Here's the BOM. I think it's complete (went over it again this morning and made a few fixes).

Raw price per kit is $56.25.

This does not include:
- shipping charges from the vendor to me,
- the price of bags and boxes for packing the orders,
- the shipping out to you.
- PayPal fee (2.9% + $0.30) per order

This is a little lower than before, and the kit price will be ammended. I have been trying to think of how to accurately get a shipping price from the vendor before actually ordering. I think I will simply estimate $7.50 per vendor.

So 7.50 * 2 = 15/15 = $1 per order.

Currently we are at $56.25 + $1 = $57.25 per kit + paypal + shipping

Great work Brian. Thank you so much!

One small typo in the parts list. The"LM319N" should be "LM318N". No big deal since we have the schematic, but it is a critical part. The digikey part number is correct.

This is a very good price for a kit like this.

Cheers!

Corrected BOM. Fixed part number of LM318.

Also, I wanted to point out that I selected the TF (insulated) version of the LM3886 so that finding insulator pads would not be an issue.

I think using the LM3886TF package is a wise choice. Finding good isolators can be a pain because some have better thermal qualities than others.
