Sorry my poor english.
Have somebody ordered jensen transformer? I want to know if its products can be oredered only by phone or fax.I have email jensen but no reply.
My DAC is build with AD1865NK,PCM1704PK,PCM63PK-2,
TDA1541A with no digital filter and AD1853,I want to know which one is the best.I also want to know the differents between DIR1703 and CS8414 ,so all chips are build in a big board.The analog part use 12au7.All the power supply use parallel adjust.
Now I have got all chips but no output transformers,who can help me?

I built a DAC with TDA1541A and CS8414 with ECC99 tube output. I find that it does not need any output transformer.
Sorry I can't help you with your other question. I know that the CS8414 is usually preferred over the DIR1703.
If you really want an output transformer, you can post in the Tube forum.

thans your reply
I just received the reply from jensen at 9:00,he said the email
was delayed to reply.
Yes,using transformer maybe no use,but I also want to try it ,because I have made some DAC without transformer sound just good and can't improve any more.My friend who made some DAC with transformer said transformer can improve sound,which fliter the high frequences we can't hear and reduce the modulate error in analog amplifing.The transformer must be good enough or it will have negative effect.By the way I use it between the
D/A chip and analog out,not behind analog amplify.
