I went for the big one - 48V >100mA
http://w1.316.telia.com/%7Eu31617586/#48%20volts%20phantom%20power%20supply
Am I thinking right - do I just split of the 48v and 0 rails into multiple DC outputs and feed these to separate 48v input of different preamps
And if so how many preamp phantom power requirements can this drive?
If it is 10 then fine - but if it is 100 then this is way overspecced..

I couldn't find any 3K 1 W resistors at RS but went for a 3.3 with 5% tolerance - is that okay
And also - the resistors are metal oxide film - is this okay?
Many thanks
