This page is for the sourcing of items in the UK/EU for Pedja Rogics' NOS DAC pcb.

Some of the components are still sourced from the US because I haven't been able to find a supply more locally yet.

Mouser electronics has a fixed shipping cost of $12 upto 4lb 2-3 weeks delivery. As the recommended CMOS clock comes from them it makes sense to order some more items from them at the same time. Also some items a priced more competitively.
