The boards and kits for the Cavalli Audio Compact Tube Hybrid are now available. For information about this amp read this thread:
Compact Tube Hybrid
This amp is a very small tube hybrid amplifier with the following features:
1. Tube stage with automatic servo that permits rolling many different kinds of common tubes not just a single rare tube type
2. A switchable heater supply that supplies either 6.3V or 12.6V
3. A discrete output stage with a discrete rail splitter
4. A HV multiplier that lets the tube run at 80V B+
5. An AMB e12 with indicator LEDs to tell you when the amp is ready
6. A compact board size of just 120mm x 75mm
7. All from a single 24VAC wall wart
This is a lot of circuitry packed onto a very small board.
Boards and kits are available from:
Spruce Canyon Labs
and more information is at:
Cavalli Audio Compact Tube Hybrid
This is a great amp and much more flexible than many of the current hybrids that are available.
I'll let the prototypers chime in on their results.
