Hi X

I know you're a busy guy but I wondered if there was an ETA for the BOM?

Putting together an order from a BOM takes me forever so any head start I can get is great!

I think you've said this amp would benefit from the highest tolerance components?

Cheers

Very good and timely question. I need the raw parts list auto-generated by Eagle from JPS64. Then I will take a crack at filling in main details like value and ratings, materials and package. If you or anyone would care to help and populate the Mouser/Digikey part numbers and even a shopping cart for the group, that would be greatly appreciated.

I'd be happy to help create an Excel spreadsheet of the BOM. Send the raw parts list when you get it from JPS64.

No problem! I don't have the technical knowledge to design circuits (yet ) so I love looking for any way I can give back to this forum. I may have a few questions about some of the items on the list along the way, so bear with me.

Update: I’m about half way through the BOM. My goal is to either have one BOM for the HPA and one for the Preamp or somehow organize a single spreadsheet to incorporate both. Let me know if you guys prefer one over the other. Once I have a draft I’ll send to X for review.
