Transformer for Pedja Rogicīs DDNF I/V Stage
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.

Just a comment: i have used a 2x21v transformer to feed salas shunts outputting +-19v. I noticed the heatsinks get very hot. I'm unsure if 24vac input to the shunts is too much/on the edge.

the heatsinks are in "good" thermic condition (200mA shunt current set with 10R).
How is your current setting for the lines?Posted 25th May 2011 at 04:38 PM by dvb projekt -
Exactly the same config in the salas regs as you use, except higher Vin and Vout... And significantly hotter (but not so hot that the fets burn), i cant hold the heatsink for longer than a sec or two

However, you could change the heatsink on the shunt regs as followed:
Standard Heatsink:
Aavid Thermalloy 513102B02500G - 11 C/W - Mouser Part No.: 532-513102B25
Hotrod Heatsink:
Aavid Thermalloy 531202B02500G - 7.5 C/W - Mouser Part No.: 532-531202B25G
