Budgie Preamp Parts List Revision

Hi Shannon,

Thanks for getting me in the forum. I just have a quick question on the parts list that you revised, just need to make sure what value to use. Below you mentioned on your post about R1 & R2 to sub from 271-210-RC to 271-215-RC - with that are you changing the resistor value and recommend using 215 Ohm instead of 210 Ohm? Another one is the VR4, should I change the value from 10K to 5K (FROM 72-T93YB-10K to 72-T93YB-5K)? Thanks!!!

1) Sub these from Mouser:

Code: Select all
C5,C6,C8   47uF 35V, 5D 2LS      647-UVZ1V470MDD      0.17
R1,R2      210, 1/4W             271-210-RC           0.13
VR4        10K Pot               72-T93YB-10K         1.58

647-UVZ1H470MED qty 3
271-215-RC qty 2
72-T93YB-5K qty 1

All those were just temporary subs as needed last June, and now they are obsolete. I've updated the Mouser Instant BOM link:
http://www.mouser.com/ProjectManager/Pr ... 3e143ddeed

Everything reverted back to the original parts list as it was in stock, except I had to sub a new part number for the 16P DIP sockets. There's a couple backordered caps that should ship in ten days. Note that I have the more expensive Nano on that BOM, so remove it if getting a cheaper eBay version.

Hope this helps!

Thanks very much for the update!!! I'm just waiting for all my ebay orders before completing the Mouser's. Mouser ship fast so I don't need to worry about it.

Thanks again
