Description

This is popular entry level home and office amplifier is available as an entry level kit. It likes speakers of higher sensitivity (above 94dB/watt) and the sound harks back to the sound of table top radios and grams of the 1950’s. 

The output stage can develop 15watts per channel from two EL84’s in push-pull. EL84’s have a crisp and clear sound that sounds bigger than the small amp that generates it.
