Jolida Music Envoy

Vacuum Tube Stereo Preamplifier w/ Phono Preamp


In excellent condition. Includes factory remote and manual. Original box and packing are not included.

The 22 pound remote controlled Music Envoy preamp utilizes the same chassis as the top JoLida hybrid integrated amp to save on production costs. The preamp uses a pair each of 12AT7 and 12AX7 tubes from China. The front panel, like monoblocks, is finished in attractive oxidized and sandblasted aluminum, which appears as whitish silver. It has 5 high level inputs, one of which is a tape loop. Also included is a full function phono stage, with variable gain, capacitance, and cartridge loading. The phono stage can be disabled for those who do not require it, adding a 6th high level input instead. Inside, the preamp has 3 separate power supplies, one for each gain stage, as well as a smaller power supply for the built in phono stage. The phono stage is fully shielded and mounted inside its own metal sub chassis. The tubes are shielded as well to reduce the possibility of both RF interference as well as vibration. High quality Wima caps are everywhere. The workmanship inside is extremely high.

Around back are the input jacks, a pair of output jacks, two pairs of tape outputs, and a plate that covers the DIP switches that control and activate the phono section. A nice touch here: a diagram is engraved on the plate to show users what positions the DIP switches need to be in for the particular cartridge used.  Also present is the connector for the Y cord to control the power amps by remote. The remote control is a smaller version of the hefty remote supplied with the JoLida JD-100A CD player. The remote controls the motorized ALPS volume pot and muting, as well as power and source selection. I am not a big remote user, but I did find myself using the preamp remote if only to conveniently supply power to the monoblocks. The output jacks have different output levels. Output pair 1 is for the monoblocks, offering 20dB of gain for power amps, output pair 2 offers 10dB for powered subwoofers or amps with extremely high input sensitivity.
