Vintage Tube & Vintage FET Microphone PCB Kit For DIY & New D7 Custom Capsule

Hi Poctop,
How did you choose the 0.32H choke for the 269 / 49 PSUs? I usually think of them being higher, 5-10H.

Hi Poctop,
How did you choose the 0.32H choke for the 269 / 49 PSUs? I usually think of them being higher, 5-10H.

1- Avaliability
2-Henry

2- DC current Max  : In General the higher inductance the lower DC Max, since i had in mind the psu to be solid with most tube configuration possible as
even for other mics some are more energy-Vorous  Heater current than others.

3- Footprints

4-Price

So basically  A trade-Off on all those things,

Be noted that the 500mH form this series will work fine , but at a cetain point filtering a already clean DC output Voltage is pointless.
dont forget the RC filetering Stage also Work well on this,

here is a quote from
http://prorecordingworkshop.lefora.com/topic/11780711/Chokes-in-Neumann-PSU


the choke is actually optional on the 2469 passive psu
you can replace it with a 10 ohm Resistor , I never had the time to actually try it with and without and compare on my list tough, 

Hope this helps,

D-Elam 251E with True Pattern Switching on PSU , I had to terminate what I started,  

this was a very fun build.  Specially the Point to Point HZ bridge,  half PCb/half PTP for the Optimal Results and Maximum Fun

Enjoy,

more Info soon,

I needed to get rid of a pair of stamping siders with the aid of a metal cutter and a file
