Transformer for Pedja Rogic´s DDNF I/V Stage

Posted 23rd May 2011 at 10:44 AM by dvb projekt
Updated 14th June 2013 at 09:47 AM by dvb projekt

If you would build the DDNF I/V stage with my PSU & Salas Shunt modules,
you could order a custom made transformer at
AE-Europe.

It has the following data:

Primary:

115-0 / 115-0
(for 115V & 230V usage)

Secondary:

24V-0-24V / 2A
24V-0 / 2A
Magnetic Shield

You could order two versions:

- Standard: EI-core € 64,-

- High End: C-core (same size as 30317) € 112,-

Prices are excl. shipping and VAT
Delivery time around 6 weeks after order.

Intel's just held their 2011 investor conference. I'm not an Intel investor but after that performance if I were, I'd have sold out by now.

Welcome to the wonderful world of ARM guys!

If you want to get down and dirty, here are a couple of articles to get you started. Be sure to check out the comments!

If you'd like an illustration remarkably parallel to Intel's style of groupthink, go here:

For all of you who want an alternative non-tube I/V stage,
Pedja Rogic was so kind and permit me to make a pcb with his circuit.

To get a smaller pcb, i made two connectors for the needed big 10µF caps.

The PCB will have the following data:

Material: FR4 - 2mm
Layers: 2
Board size: 110x95 mm
Surface finish: Immersion Gold
Copper weight: 70µm
Soldermask: Both sides - green
