Hi Savvas,
the PRP resistors were my choice, because they have a real good reputation.
Surely you could use the Dale´s, also.
Is there an up-to-date BOM for the project ?
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.

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 shunt´s to the Takman REX carbon type
- Delete the 0,1µF bypass caps for all shunt´s
Merry Christmas to all of you 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...

The Ultra High Speed Buffer PCB´s arrived!
That´s the "ready to use" module, witch will be shipped.
As i wrote before, you could use it on top to the
Twisted Pear "Opus WM8804 Receiver" Module.
I am just waiting to the 3-pol Wago Terminals that i´ve ordered.
After checking the module, i will collect the money for the pre orders.

An externally hosted image should be here but it was not working when we last tested it.

Many thanks Oliver my +5v regulator pcb arrived this morning
To use as a +12v output regulator is it just a case of changing the value of the trimmer? tia
Yes. Use a 5K trimmer, like in the -15V shunt line.
