Let's meet this man who chooses his own direction, and gives generously to the audio DIY community. |

SIT Nemesis!
Nelson Pass
 In Linear Audio Vol 0, Nelson Pass paid tribute to the classical single-ended transformer-coupled triode amplifier with the Arch Nemesis. Inspired by Jean Hiraga's Nemesis, Nelson enlisted a Silicon-Carbide power device to produce a very simple design with great musical performance.
Not one to rest on his laurels, Mr. Pass had a batch of custom-designed Static Induction Transistors manufactured. The Pass SIT1 improved the SiC based Arch Nemesis design another notch. SIT1 is not available commercially but Nelson predicts that similar devices will soon enter the market. Such a device, together with a suitable output tranformer, will form a nice construction project. Watch this space as well as www.passdiy.com !
