RE: BDT Preamp Schematics

I emailed Dave Slagle for prices & any spec info he was willing to provide - just got price of $350 a pair & it's wound on a nickel core.

I can't afford them at this price so I'm wondering what could substitue for this - Im thinking that a PS toroid might work here - I've heard these used as input & output transformers with great effect.

Any ideas - what impedance does the SAR8 tube like to run into?
