READ ENTIRE INSTRUCTION MANUAL BEFORE USING

1. SAFETY INSTRUCTION

Read Instructions-All safety and operating instructions should be read before the amplifier is operated

Retain Instructions -Safety and operating instructions should be retained for future reference.

Heed warnings-All warnings on the amplifier and in the operating should be adhered to.

Follow instructions-All operating and use instructions should be followed.

Water and moisture-The equipment should not be used near water, e.g., near a bathtub, washbowl, kitchen sink,

laundry tub, in a wet basement, or near a swimming pool etc.

Ventilation-The equipment should be situated so that its location or position does not interfere with its proper

ventilation. So the equipment should not be situated on a bed, sofa, or similar surface, e.g., that may block the

ventilation openings, or placed in a built-in installation, such as a bookcase or cabinet that may impede the flow of air.

The equipment should be situated away from heat sources such as radiators, heat register, stoves, or other electronic

appliances that produce heat, so it may not suitable for commercial use.

Power sources-The equipment should be connected to a power supply only of the type described in this manual or as

marked on the equipment.

Grounding or polarization-Power-supply cords should be routed so that they are not likely to be walked on or

pinched by items placed upon or against them, paying particular attention to cords and plugs, convenience receptacles,

and the point where they exit from the amplifier.

Power lines-In case of connecting a tuner, an outdoor antenna should be located away from power lines. If an outside

antenna is connected to the system, be sure the antenna is grounded so as to provide some protection against voltage

surges and built up static charges.

Any Servicing-The user should not attempt to service the equipment r beyond that described in this manual. All other

servicing should be referred to qualified service technicians

CAUTION:

TO PREVENT THE RISK OF ELECTRIC SHOCK, DO NOT REMOVE COVER (OR BACK). NO USER-SERVICEABLE

PARTS INSIDE. REFER SERVICING TO QUALIFIED SERVICE PERSONNEL.

The lightning flash with arrowhead symbol, within an equilateral triangle, is intended to alert the user to the presence of

uninsulated

“

dangerous voltage

”

within the product's enclosure that may be of sufficient magnitude to constitute a

risk of electric shock to persons.

The exclamation point within an equilateral triangle is intended to alert the to the presence of important operating and

maintenance (servicing) instructions in the literature accompanying the appliance.

. WHEN YOU OPEN THE BOX Before any Opera audio product leaves the factory it is carefully inspected for physical imperfections as a routine part of Opera audio's systematic quality control. After you have unpacked the equipment, inspect it for any physical damage. Save the shipping carton and all packing materials, because they are essential to reduce the possibility of transportation damage. Because some heat is generated by the equipment, adequate air circulation is provided to maintain cool operation.

For best performance, the load presented by the speaker has to match the amplifier's output impedance. Refer to the manufacture's information for your speaker nominal impedance. All the vacuum tube amplifier made by Opera audio are factory set to match the speakers at 8 ohms and 4 ohms. If you have a problem Legal consumer protection varies from country to country.

for high sound quality. Systems incorporating moving coil phono preamplifiers and active crossovers are more likely to suffer. Your Consonance hi-fi system can be damaged by lightning. Power amplifiers are particularly at risk and should be turned off when there is risk of lightning strike. For complete protection all mains plugs and any aerial cables should be disconnected when not in use.

which acts as input stage and then to the 2 6SN7 dual triodes which acts as drive stage. The 2 6SN7s provides voltage gain and drives the EL34 output tube(one matched pair per channel). The EL34s are transformer-coupled to the load.

2) Occasionally a tube will develop a small leak. When air gets into the tube, AND when the high plate voltage is applied, the air molecules can ionize. The glow of ionized air is quite different from the fluorescence glow above-ionized air is a strong purple color, almost pink. This color usually appears INSIDE the plate of the tube (though not always). It does not cling to surfaces, like fluorescence, but appears in the spaces BETWEEN elements.

DC power at all times. It is dependent on the circuit design. The only way to see if you need an amplifier with a regulated supply is to listen to it and carefully compare it with similar amps with unregulated supplies. F. There's all this talk about "parallel feed", "shunt feed", SRPP, "mu followers", and the like. Which should I use? What's the difference? Parallel feed and shunt feed are the same technique.
