The first step in preparing your MET1 preamplifier for use is to install the vacuum-tubes. To do this, remove the top plate of the tube guard by removing the three socket-head screws using the supplied hex-head screwdriver. The MET1 uses six type 8080 tubes.

Physical location and cable “dress” can be an important factor in minimizing hum pickup. The installation should situate the preamplifier well away from the power amplifier, and power (ac mains) cords should be dressed to remain at least 4" (100mm) away from input/output cables.

Observe the coded polarities (“+” and “-“). CONTROL IN: A connection for wired remote control input. This allows the MET1 to obtain its control instructions from an IR receiver located on another unit, or directly from a wired system remote-control panel.

Tube Replacement The MET1 circuit employs six vacuum tubes, all 6C4/8080s. The brands of tubes we supply have been chosen by first selecting those brands which are known to be most reliable, then by extensive auditioning of these acceptable brands with the final choices being made solely on the basis of sonic performance.
This will be the case if the number of phase inversions is even (or zero). The MET1 is phase inverting. If your system has an odd number of inversions, (for example, if the MET1 is the only phase inverting unit in the chain) then you must add one phase inversion.

Fuses In addition to an ac mains fuse (F3) located in the IEC inlet socket, the MET1 has individual fuses located on the main pc board protecting each of its two power transformers (one for the tube circuitry, one for the control circuits). A failure of any of these fuses is a symptom of a more serious problem, and a competent service technician should be consulted.
