Hi Savvas,

the PRP resistors were my choice, because they have a real good reputation.
Surely you could use the Dales, also.

Based on Oliver's original BOM, I wrote a little spreadsheet that works out what to order from whom. It's easy to change quantities and add or delete components as you go along.

The downside is that it also tells you what you have spent - or are about to spend.

If Oliver has no objections, I'm happy to forward it to anyone interested.

HTH

Thanks - my concern was that during the journey there had been changes - but a nice spreadsheet would be great (I can always delete the cost column!!).

Here it is. There's nothing fancy and it should be easy to "localise".

Notes:

* You must fill in row 4 with the number of modules to be built.

* Items in a strike-out font are part of the original spec but had to be substituted. It made sense to keep them in the list but mark them.

* You need to put your suppliers in column I and edit J66 to J72 to match. If you add new rows for parts not on my list, you need to edit the range as well.

Usual disclaimers apply. Let me know if (when) you find errors.

Very cool spreadsheet! Only two changings on Salas recommendation:
  • Change the 220R resistors on the shunts to the Takman REX carbon type
  • Delete the 0,1F bypass caps for all shunts

Merry Christmas!

Christmas holidays, always a good opportunity to do some diy. Unfortunately, since I am travelling to family abroad it will be limited to some 'paper research'... currently trying to figure out the functioning of the Pedja Rogic Diamond I/V stage.... not very far yet.... if someone knows good (dummy) literature on such discrete stages let me know...
