Product Summary

The products we are offering are based on basic design specifications:

true monaural design, with each channel having its own parts and power supply;
driver and output tubes are coupled using only the highest quality interstage transformers;
transformers wound to 3 Dimension Audio proprietary specification by Electraprint;
dedicated chassis for power supply;
custom chassis that are designed to control resonances and absorb vibration.

From within the above basic design guidelines we provide you a variety of choices in amplifier design using combinations of different driver, output, and rectifier tubes. We believe that the best tubes are the 2a3, 300b, 845, and 211. Single ended or push/pull interstage coupled amplifiers can be supplied based on each output tube. Other tubes such as the 50 or Western Electric 205 or others can be utilized if you wish.
