Phenix G3/Chinese Earmax


Posted on Feb 6, 2014

This is the version with 3 6N11 tubes. And as far as I can see identical to the Phenix. It looks and feels very well made. The separate power supply is a bit bulky but works well and keeps the size of the main box small and cute. The on/off switch is situated on the powersupply. Not very convenient because you can`t tuck it away somewhere under the desk. But is is sensible in respect to sound quality

otherwise you would have to loop an extra 2 high voltage AC wires through the DC power cord. First thing I did was put a power cord with a euro-plug on the powersupply. The powersupply is full of hotmelt and double-sided foamtape, so nothing will resonate. I was looking for a real tube amplifier I could hook up to my modded Muse NOS 4xTDA DAC so I could listen to any difference or improvements in sound. I wanted something not too expensive (there goes the majority of HP-amps), using tubes that are current (so no Little Dot), not too expensive replacing and good for audio. I have come upon a batch of Philips Miniwatt tubes last month that had several ECC8* tubes. The $50 Indeed/Muse is a hybrid transistor that has severe high rolloff so there wasn`t much left out there. Then I stumbled upon this (item had no photo) in the Ebay store of a Chinese seller that has some nice pre-modded stuff. This turned out to be exactly what I was looking for. I wouldn`t opt for the G3 T7 with the ECC81 in the middle because that`s a bit of a wimpy tube. Even though the inside wasn`t exactly what was advertised (Wima MKP 10 turned out to be Ero 1860 polycarbonate which some find to be very good but I didn`t). The power switch seems to be a bit oxidized in storage because it wasn`t very reliable at first. I needed to flip-flop it a few times to work the first week. Yhe volumepot gives me some static because I modded my NOS DAC so it has no...
