Dear Evolution-ites... In our continuing efforts to educate the audio/video masses, we are pleased to offer this series of meaningful dissertations from our resident 2-Channel Guru, John Guidi. It shall be named -
...that's Bob Carver's Black Magic 20 Vacuum Tube Amplifier
of course. Not only will your plants thrive, the entire family will be happier and healthier listening to Bob's luscious little amplifier.... the wife, kids, dog, iguana, the whole ''FamDamly'' For such a compact little amplifier
(13'' x 9'', 19 lbs), this baby produces a HUGE soundstage but with tight, pin-point imaging and bass extension and control that belies its 20 watt per channel
rating. These amps provide a warm, rich sound that's pure audio nirvana, sure to put a smile on everyone's face.
This amplifier has many deluxe features not normally found on units in this price range. An automatic DC restorer and bias circuit for each channel eliminates the need for tube matching and biasing. Output tube idle current is very low, which greatly increases tube
life. It has ultra-wide bandwidth output transformers with interleaved windings capable of the most nuanced voice as well as huge peak output capacity. It has a volume control that allows you to fine tune the level with your preamp or connect a ''line level'' source directly and eliminate a preamp. When the time comes for more power, get a second amp and with the flick of a switch they can be converted to 40 watt Mono Blocks. A very well thought out and versatile amplifier. Bob Carver's amps are hand made in the USA using the highest quality parts available with point to point wiring, not printed circuit boards and will last a generation and be serviceable 50 years from now. It comes with a 7 year warranty
(1 year on tubes) and when you consider the overall sonic performance and quality, is a bargain at $2100
. When you consider how much fun you'll have with this amp it's a downright steal.
