Ordered the output transformers for the 26 Usagi preamp. I'll be trying out my first set of Lundahl transformers in the form of the LL2763A which has 4+4:1+1+1+1 taps for 8:1, 4:1 or 2:1 ratios. I was thinking of a 2:1 primarily, but couldn't really make up my mind. Now I can have it both ways :) The rated 7mA and 280H is perfect for the 26.
Along with the 26 stepdown I also scored some Amplimo 18V/4A transformers that were on sale for €12 each. These will go into the filament supplies for the Usagi and Yojimbo amps.
