Fascinating! I wonder how the tubes would like a 1.2 volt trident on the Buffalo VDD? I imagine it would be money well spent.

Hi Felipe,

The R-cores are custom built from a place in Indiana (USA) called custom magenetics. They are very well built using winders made by Kitamura Kiden (The company that invented the R-core transformer). They are both 50 VA load and are dual primary (115V or 1230V possible) and dual secondaries (the red are 150V, 0.1A) and the yellow are (9V, 2A). They could do more secondaries if you need them. Both R-cores cost me $195.70 USD with shipping within the USA if I remember correctly. The R-core part number is: 1292-R-001 if you want the exact same transformer. The web site can be found here: Custom Magnetics, Inc.. I hope this helps you out. Thanks for the comments.

Greg

I am thinking of getting the tridents Frank. I have read they improve the sound (imaging, separation, dynamics, etc.) I have also read a number of people having problem integrating them onto the Buffalo II board though. I want to make sure I wil not have problems with them and when I am sure about the upgrade I will do it. I agree for the amount it costs for the Tridents it seems like a good deal.

Sorry, I know they were some big pictures. Unfortunately I didn't realise it until after I could not edit them. I'll make sure they are smaller in the future.
