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 150uF 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"
