Trafomatic Audio 101D/n Line level preamplifier






































Trafomatic Audio's newest preamp harnesses the 101D triode which was first made by Western Electric for telephone repeaters between 1921 and 1930.

Current production 101Ds have previously been seen in preamps by Supratek and Melody but never as the exclusive output device.
Rectification and voltage regulation are via small-signal tubes.

The SM-101Dn offers five RCA inputs and 2/1 RCA/XLR outputs.
