Svetlana 572-3

The Svetlana SV572-3 is a power triode intended for use in class A, AB, or B audio amplifiers.

This tube features:
- Directly heated thoriated tungsten filament for soft glow and warm sound.
- Hard glass envelope with white ceramic base.
- Low microphonic construction with ceramic internal spacers.
- Graphite plate with titanium coating for extremely high power capability and inherent gettering.
- Tri-plate anode.
- Superb aesthetic appearance.
- The SV572-3 has a plate dissipation of 125 watts maximum, making it useful in applications where a 100-watt triode (211 or 845) would normally be used, while having lower plate resistance, lower filament power and a smaller physical size.
