Dear Music Lover , Since 1972, I have been committed to developing state of the art audio products that enhance our love of music. It is clear to me that the audio world has become oriented towards complexity and mediocrity . Even high price tags do not guarantee sonic quality or a good investment. In December of 1998, I founded Red Rose Music to f[...]

A Message From V ictor T iscareno: Chief Designer , Red Rose Music At Red Rose Music we have built our reputation and design philosophy around the use of high- performance power supplies in vacuum tube components. W e believe that a good circuit can only sound as good as its power supply . Our experience has taught us that providing the best possib[...]

The choice of an amplifier circuit type is also extremely important. In theory , a push-pull amplifi er circuit produces more power than a single-ended design and it cancels out even-order distortion, but most push-pull amplifiers never reach this theoretical ideal. Although most tube amplifiers sound better than the majority of solid state designs[...]

Model 5 Integrated Amplifier Features: • Selected and matched EL-34 and 12A T7 tubes • Onboard plate current meter • Switch selection of T riode or Ultralinear mode • Five line stage stereo inputs • Unbuffered line-level T ape outputs • Regulated power supply for output tubes • Separate reference supplies for high voltages • Heavy-d[...]

A T our of Y our Model 5 Amplifier 1. Program Selector The position of the Program Selector switch specifies the currently active program source. Each position on the Input Selector switch corresponds to a pair of input connectors on the rear panel. 2. V olume Control The V olume Control is a precision step attenuator switch that adjusts the amplif[...]

6. Power Switch: ON The ON setting is the normal operating position. When you turn the amplifier on, it may enter the warmup timing cycle for approximately 30 seconds while the tube filaments reach operating temperature. During warmup, the Mode Indicator LED lights in orange. When the amplifier is ready to operate, the Mode Indicator LED lights in [...]

1 1. Gr ound Switch (Right Channel) Use the two Ground Switches to eliminate hum caused by ground loops between the amplifier and other components in your audio system. The Ground Switch has three settings: COMMON When the switch is set to COMMON, the signal grounds for both channels are tied together . This setting overrides the FLOA T position of[...]

15. Feedback Control (Left) The Feedback Control switch is a rotary switch that sets the optimal feedback level for speakers with different impedances. Use a small screwdriver or alignment tool to move the red mark next to the impedance of the speaker connected to the right channel of the ampli- fier . If you don’t know the impedance of your spea[...]

27. Fuse for Output T ube V1 The 250 mA, Micro fuse protects the amplifier circuit from overcurrent conditions in the output tubes. When an output tube fuse blows, or if a fuse is not in its socket, a red LED indicator at the front of the corresponding tube socket lights. If a fuse blows, disconnect power from the amplifier , either at the IEC powe[...]

34 – 37. Output T ube Sockets V1 – V4 The four EL-34/6CA7 output tubes supplied with the amplifier fit the Output T ube Sockets. The base of each tube is marked with the socket number where that tube was used when the amplifier was aligned at the factory . For best performance, each tube should be used in the corresponding socket. The front of [...]

10. Insert each of the output tubes into the socket with the number that matches the number marked on the tube. Carefully align the key in the base of the tube to the keyway in the socket. T ake care to avoid damaging the positioning key on the base of each tube. If you did not use the cotton gloves, wipe the glass part of each tube with a clean so[...]

16. W ith no program playing, listen to your speakers. If you hear a loud hum, turn of f the ampli- fier , unplug and reconnect the interconnect cables at both ends and turn the amplifier back on. If the hum is still there, try dif ferent settings of the two Ground Switches until you find the combination that produces the least hum. Y ou should be [...]

Replacing the Output T ubes There are two possible reasons for replacing the tubes in your amplifier . Either the tubes supplied with the amplifier have worn out, or you want to experiment with a different brand of tubes. The tubes supplied with your amplifier will meet or exceed our minimum performance specifica- tions, but “super premium” tub[...]

W ater and moistur e: This product should never be used near water . T o prevent fire or a shock hazard, do not expose the Model 5 to rain or moisture. The Model 5 is designed for indoor use only . Never use any liquids in and around the Model 5 that may run into the chassis or onto live circuits. Heat: Place Model 5 should be located in a cool, dr[...]

Symptom: Distorted audio Make sure the Power switch in set to ON rather than STBY T ry changing to a dif ferent program source. If the distortion only exists on one source, check the component that produces that signal. If an FM signal is distorted, try listening to the same station on another radio. If the distortion exists on more than one source[...]

Service and T echnical Support If your amplifier requires service, you may either consult your Red Rose Music dealer , or send it directly to Red Rose Music. If you choose to return it to the factory , please call us first. If we can diagnose the problem by tele- phone, we may be able to tell you how to fix it without the inconvenience and expense [...]
