Bella EXtreme 100 

Custom Mundorf Silver/Oil
Monobloc Amplifiers

 

Carefully designed to deliver a well-balanced musical presentation and long-term listening pleasure, the Bella EXtreme 100  monobloc amplifiers combine the finest sonic attributes of classic tube amplification (midrange accuracy, smooth tonal character, and smooth yet extended high-frequency resolution) to enhance the listener’s emotional involvement with the music.

As with all Bella EXtreme products, the Bella Extreme 100 amplifiers utilize a unique circuit design that demonstrates our beliefs in using premium parts, shorter signal paths, top notch build quality.  Every pair of Bella EXtreme 100 monobloc amplifiers are proudly hand-made in the USA and carefully tested, inspected, and packaged before being sent to you for your listening enjoyment.

What's inside

• Mundorf Supreme Silver/Oil or Silver/Gold capacitors installed in the signal path coupling stages

• Mundorf Supreme Silver/Oil or Silver/Gold capacitors installed in the single ended input stage

• SoniCap Gen II innerstage coupling capacitors

• Elna Cerafine cathode bypass capacitors at the 6SL7 input tube.

• Mills non-inductive grid stop resistors

• Mills non-inductive screen grid resistors.

• Mills non-inductive cathode resistors

• Dale/Vishay 1 watt, 1% non-magnetic signal path resistors

• Dale/Vishay 1 watt, 1% non-magnetic resistors are used in the bias stage in series with the main coupling capacitors for tight control on bias settings preventing bias drift.

• Dale/Vishay 3 watt, 1% wirewound resistors are used in various power supply locations.

• All exposed resistors leads throughout the signal path have heatshrink applied to help reduce mechanical vibration as well as preventing circuit shorts.

• The ground layout is designed to provide the best possible results with a dead quiet background and lowest noise floor.

• Fairchild "Ultra Fast - Soft Recovery" diodes are utilized in the rectifying stage of the power supply.

• SoniCap Platinum Teflon power supply bypass capacitors.

• Silver platted copper signal wire

• Neutrik XLR input connectors. NOTE: These amplifiers will be built standard with single ended inputs only. If you desire balanced inputs, there will be NO ADDITIONAL CHARGE for this option.

• High quality RCA input jacks.

• Valve Art KT88 output tubes

• All amplifiers are bench tested for 2 hours

• Minimum 12 hours system burn-in.
