transformers for the B283
« on: July 07, 2010, 04:00:22 AM »
What transformers and/or ratios suit the b283 card?  I know that Carnhill carries a version of the original TX but is there a cheaper option or a different option?

because of the high DC current going through the primary you need a gapped transformer. the only alternative to carnhill that I am aware of is ed andersons version, which you will find at hairball audio on the white market. I tried the same build of a peter purpose EQN with both the carnhill and the ed anderson transformers and they both sound great.  :)
you should check if JLM do a neve type output transformer, as this would save you on shipping on these weighty buggers...

Yeah Joes 111DC does the job!

"less muddy LO1166" he calls it!

unless of course it is Nv mud you are chasing!!
