With regards to the BOM V1

Should the 10k SIL resistors RP9, RP10 and RP900 Mouser code be 652-4609X-AP1-103LF? It currently has a Mouser code for a normal 10k resistor.

Yeah looks like a mistake.

Guess I'll be the South end of a North bound horse today. For OSX Numbers here's how one opens a .ods file.

And then your get;

Gotta be a Windoze thing... Guess I'm a horses as# for today.. :oops: :oops: :oops:

Build the remake without part numbers so should have been able to do the H4 if not for that pesky SMT stuff. :oops: :oops: :oops:

.ods is the default file format for Open Office btw.

Hmm. Found some small error I think in the BOM:

Cap C46, C47 and C48 is listed as 0805 package/SMD, 50pF but mouser part is 80-C315C510F3G5TA. A Thru hole cap. Part of DAC circuit. Must be wrong?

C10 doesn't have a mouser part number. Part of the audio circuit.

Good spot! Will be uploading a updated list later today hopefully.

V3 parts list now uploaded. Various fixes & additions in parts numbers. Added some sockets to the bottom of the list. Added Rapid & farnell for UK people. Prices are for Rapid and farnell, this is really for my own build of boards, so probably no use to outside of UK people.

Thanks exxos, I was planning to order from Farnell.

By the way. Can you use the 32MHz oscillator (2 pin) which I have desoldered from my donor board instead of the XO 4-pin which you have chosen on the mongrel build? The XO have GND, +5V and clock signal. The 2 pin have +5V and clock?

2 pins variants are crystals. They are not the same as 4 & 8 pin oscillators.

If you really want to use 2 pins, your gonna have to build this circuit to go along with it ;)
