I have sourced a great transformer for this project. Like any other buy, the multiple cost of 5 to 10 is really a great price. A PM from Oliver OK'd this GB and he even helped me get the international voltage fixed.
Here are the details.
Toroidal Power Transformer
Dual Primariess for use in USA & International input.
PRIMARIES ARE INSIDE A SLEEVE.
7 Secondaries:
4 x 12V @ 1A, 1 x 20V @ 1A, 1 x 9V @ 2A, 1 - 150V @ .1A.
ISO 9001:2008 - Certified - 3 year warranty.
Company has 30 years of Design & Manufacturing experience.
LEADS: S=Multistranded wire. Length tolerance: +/- 1/2".
Manufacturing tolerance is +/- 3%.
NOMINAL SUPPLY: 117/234V +/-10%
RATED PRIMARY CURRENT: 1.0/0.5A
RATED FREQUENCY: 50/60 Hz
TEMP. RISE AT RATED LOAD: 38 ºC
DIMENSIONS/WEIGHT: OD = 3.9" - H = 1.8" - WEIGHT = 3.1 LBS
MOUNTING: WASHER/PADS = 70mm - THICKNESS = 0.05" - HOLE DIAMETER = 0.25"
Mounting Hardware: Includes a metal washer and 2 rubber pads.
CORE DATA: CORE # 900140 - CORE LOSS = 0.9 W - NO-LOAD CURRENT = 7 mA
Dimensions stated above are nominal. Tolerance is +/-10%.
OTHER SPECIFICATIONS: Transformer meets UL506, EN 61558 and CSA C22.2 No. 66 standards. ROHS compliant. Class B insulation.
Cost each before tax and shipping for 5 units is: ~$150. Cost each for 10 units it gets down to ~$115
If there is interest, I will get costs, for shipping & handling information put together. I am in California, USA
Thanks for looking,

Hi Aguaazul,
Why four 12v secs? If I am correct, 3 are needed... +5, -5 and 3.3 volts.
The 20 volts sec is for the -15 volts and the other two left are for the Tube-I-Zator.
Is that fourth 12v for accessories like spdif to i2s ?
Maybe is a dumb question but I was curious....
Regards
Jorge

Transformer for Red Baron V5 & Tube-I-zator V3.1 - Update
I just ordered a prototype in USA only voltage. When it get's to 10, I'll put together final pricing. The company will handle all the shipping directly.
On the secondary wiring I chose to have the + voltage a solid color and the 0 voltage a corresponding color with a stripe.
