Manley Mahi Monoblock Amplifiers

A 40 Wpc design with EL34 power tubes, 12BH4EH driver, and 12AT7EH input tube

These cute little Mahi monoblock amps produce around 40 watts RMS in Ultra-Linear mode or around 20 watts in TRIODE from a quartet of EL84 / 6BQ5 tubes driven by a 6414 dual triode driver and a 12AT7EH input dual triode. The EL84 has been one of Manley Labs’ favorite tubes for many years; extremely long-lasting and reliable, and can be considered the smaller brother of the much beloved EL34: really quick-sounding both in the bass and especially in the top end. And of course this has a lot to do with the Manley output transformer, the same one built for the Manley Stingrays.

We believe the Manley Mahis give a lot of value for an affordable price and we think you will be surprised at just how big these little guys sound. You have no idea how fabulous these amplifiers are.
