The best conditions for a TP Buffalo IIISE
Hello folks,
I am pretty new at this site and this is my first thread in here..
I have assembled my Buffalo IIISE dac and I had some trouble with it, no sound on the output, but it seems to work out now..
I have read some threads regarding transformers directly on the dac output for I/V before an output stage. I don't have any experience with tranformers so I have been through this thread:http://www.diyaudio.com/forums/twisted-pear/164294-buffalo-ii-transformers-19.html
Joe Rasmussen put some examples on page 19. But I have to admit - All these post and meanings can confuse me a little..
That's why I am starting this:
I want the "best" terms of working conditions for my dac. I know about the brands Sowter and Lundahl.
I want to go fully ballanced with tubes at the output, with an amplifying circuit for both + and - (the rest of my setup is so)
On page 19 in the other thread, Joe Rasmussen posted example D, that looks interesting: The dac looks into an impedance close to zero, as I understand is best for this dac to performance. But I want the - pol to be amplified by tubes to.. And there is only one primary on the trafo: What about this one from Sowter for an example: http://www.sowter.co.uk/specs/9545.htm
There is two primary windings - One for + and one for - Fully balanced.
30mV out in Joe's example is not much and will need allmost an RIAA amp. So I thought of an stepup trafo like the Sowter I gave as an example, and after the trafo, a tube amplifying circuit with decent gain for both + and - and then we go
I'm not a technician (I'm building quality loudspeakers as my hobby) so maybe I'm in deeb for sure.. Tell me, am I on the totally wrong path here?
Please help me out, it could be nice if someone could tell me which trafo (brand, type and resistors) I should go for.
I know I should try alot of different trafo's and stuff but financially its not an option at the moment..
Is there someone who can lift the fog for me
Best regards from
