Re: Lundahl Transformer Attenuator??

You won't have much to worry about with what you put on the output side of the TX-102, because it steps down the source impedance of whatever you feed its input (except at full volume). The area of concern is what you connect to its input. A tube RIAA with a plate-loaded output, such as the RCA circuit, will very likely have bandwidth problems when driving a TX-102. OTOH, a phono stage with a cathode follower output or a step-down transformer will have no trouble.

Bent Audio only sells the MK II versions now, as far as I know. There are no differences between the MK I and Mk II that would involve usable impedances.

For a thorough discussion of these units, you might find Thorsten Loesch's application note useful. This is posted at the Bent Audio forum on Harmonic Discord--the link appears below.
