State of the art vacuum tube amplifiers by Bob Carver. These modern vacuum tube amp designs have all of the vacuum tube musical advantages without the once inherent shortcomings.

Historically, High end vacuum tube amplifiers have offered amazingly musical sound, but they came with some sacrifices, such as:

1. Constant tube degradation and declining performance, resulting in frequent tube replacement cost to maintain ultimate performance.

2. High heat output and instant burn risk, requiring guards and cages, combined with heavy electrical consumption and eventual heat degradation of component parts.

3. DC voltage sag under load, providing less than accurate bass response.

4. Speaker choices limited to highly sensitive models with higher Impeadance ratings.

WHAT MAKES BOB CARVER VACUUM TUBE AMPLIFIERS DIFFERENT?

Bob Carver - World renowned audio designer and physicist (Robert W Carver, Phd) has addressed these sacrifices. Bob Carver offers world class performance without the once inherent tube amp shortcomings.

1. Tube life on a Bob Carver is measured in decades, not week or months. Maintenance and cost of ownership is minimized, performance is consistent, reliable and improved. The musical performance is powerful, musical, accurate and captivatingly tube amp beautiful.

2. Lower heat, reduced burn risk, lower energy consumption. Chassis temperature is about 99F in a 70F room. Amplifier internal parts stay cool. The result is low heat exposer and long service life.

3. Bobs DC restorer circuit prevents the bias from sagging under load. This is a type of tracking bias supply. The result is the most defined, textured and musical bass instrument resolution we think you will find, from any type of amplifier, tube or solid state.

4. Speaker choices are not limited. We provide demos using speakers with efficiencies as low as 83 db/w/m with impedance dips of over 3 ohms. These amps are stable at 2 ohms.

We order these hand built, Made in USA Vacuum Tube Amplifiers, many months in advance and make every effort to keep stock available to our customers.
