Kutya'i: The worlds most powerful hi-fi amplifier

Kutya'i is a push-pull amplifier that is currently at the concept stage.  It will utilise 10 5J/180E tubes in push-pull, biased at the very limit of conduction in order to maximise efficiency. By using much more powerful, 3-phase air-blast units, we hope to increase their maximum anode dissipation to 7kW each.  In conjunction with the biasing outlined above, and by over-running them at an HT of between 9kv and 12kv, we expect to obtain nearly 50kW per pair, or a quarter of a megawatt overall.

This is obviously well in excess of the power supplied to our workshop by the power utility, and so we will rely on the stored energy in the EHT PSU for testing.  This will be based on several hundred 150µF 330v electrolytics arranged in parallelled series chains.

Completion date for this project is Dec '00, and it's story will be published in Jan '01 in a book entitled "Kutya'i: The Beauty of Dreams - the story of the world's most powerful hi-fi amplifier"
