As you might be aware from reading my blog, I'm using Lundahl transformers and chokes extensively. I'm especially fond of the LL1933 MC step up transformer which is my favorite. I actually prefer the mu metal core LL1933 over the amorphous core LL1931. Both are also available with higher step up ratios as types LL1943 and LL1941. This series of transformers is wound with Cardas copper wire.
Now they are also available with silver wire, the suffix 'Ag' distinguishes them from the standard versions:
During the high end fair in Munich this year I met Per Lundahl and we discussed silver wound transformers. Apparently there is quite some demand and I also encouraged him to go for silver. The MC step up transformers are the first ones to be available as silver editions.
I got my hands on a pair LL1933Ag of the first production run and will compare them to the standard transformers which I use in my phonostages.
Stay tuned for another article about the impact of the silver on the sound of these transformers.
