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.

- Note that the schematic shows flip-flops' preset and clear pins left floating, and there are flip-flops that won’t work unless these pins are externally pulled high. In other words, pins 1, 4, 10 and 13 must be additionally connected to +5V. I can say that the LS (by ST) and F (by Fairchild) flip-flops worked with these pins left unconnected, but VHC, HC and AC (all by Fairchild) needed this external pull up. F series is open and defined but is not as full and clean as VHC.
