Green pre pcb and PSU pcb layout

82 x 59 mm

Once you have done the conversion, you can check on the size of a resistor, should be .4" hole centre to hole centre.

resolved ...it should be 85mm x 60mm to be properly scaled - damn printer settings !!!

peter - many thanks again

now good to go - etching later today.

[PeteC]

All etched !

one further question ref the Green PSU V6 - will it power 2 mic pres OK, if my TX has enough VA headroom ?

cheers

I would say up to 4...

 

[PeteC]

great many thanks gemini86 - now you've got me thinking about a x4 pre rather than x2. !!

The more the merrier!

I have done up to 8 Green channels on this supply.

The regs got VERY hot so I mounted them on the case, no more heat probs.

Hi

I've noticed 2 switches on pics of the green pres - I am assuming one is to switch in phantom power ( as per schematic ) and the other is a phase switch to switch hot and cold at the output - Is this correct ?

sorry for Q's but its not so easy to find in META which I've been browsing mucho.

Depending on the rev, there is also a HPF switch.

 

[PeteC]

thanks ,
its the early version and  just the 2 switches - must be phantom ans phase I guess

[peterc]

There was no HPF on the first version, so the 2switches were definitely phantom and phase

just a quick question on the caps in the V6 power supply

the 1000uF caps are only rated at 10v - is this right - I dont have the schem but expected higher voltage rated caps ?

I've ordered everything else I need for a Dual pre - with sufficient Power supply headroom to make it a quad later.

Keep the electrolytics to 25v or 35v, 100v for the phantom supply tripler

Peter

 

[PeteC]

thanks - the 100v are the 47uf caps then

so OK for the 1000uf to be 25v /35v

I'll go with that - many thanks Peter

itching to get these built now.
