All.ods.  you can also use this file and open it with  OpenOffice - export it to a CSV file and import it on mouser import tool.  

important

update 2024:   don't use low ESR Caps at the LDO outputs (LM2991/LT1963) otherwise you can run in unstable Voltages, Defect regulators, circuit swings - ripple.

I ordered from: TME, mouser, thonk and musikding

my mouser cart: http://www.mouser.com/ProjectManager/ProjectDetail.aspx?AccessID=0901ddef92

this cart is limited to my own usage for one device - you need to order standard parts like resistors from another source to save money.

for male/female headers use a different brand or headers with more pins in case they're out of stock.

order 10 resistors instead of 2 and you'll get the better price.

not including all ic-sockets

  1. Don´t install the header as described at the beginning of the build - otherwise you run in trouble ( normally is the process: put the male and female header together, put it on one board and use spacers and screws to hold this in correct place/alignment,

then solder the male/female header. this is the only way to get a correct alignment of the pcbs and frontpanel.

2. solder the 4x TL1963 and lm2991 not to close together - or you risk a short between the solder points or regulators.

3. use matched transistor pairs as described in the buildguide, but from my pov. you cant match a 2N3904 and 2N3906 to the same value.

make sure you installed a jumper on JP10(2pins)  and JP19 (3pins) (bridge the second and third pin with a PC jumper)

(my analog board picture shows my build with one failure - near the 2N4402 are 56K instead of 56R in the picture)
