Section 2. You can skip sections 3-7 of the manual until you need them. Feel free to contact Tavish Design if you have any questions (info@tavishdesign.com). - Page 4 (“ready”) and the output relay will close, indicating that the amplifier is ready to use. Adjust the volume control after the green “ready” LED is glowing, since the Minotaur won’t pass any signal until then. The MUTE button is useful for temporarily muting the output without adjusting the volume control.

(it is secured in place with tamper-resistant screws). Refer servicing to Tavish Design, LLC. If the unit must be opened for servicing, unplug it and wait at least 30 minutes for internal capacitors to discharge. The bottom cover is secured with T15 Torx screws. -
Page 6: Description And Specifications
The Minotaur is one of very few hybrids on the market to directly couple the tubes to the transistors. In developing the Minotaur, particular attention was paid both to achieving very low distortion, and also to the character of whatever small distortion was produced;... -

It is even more essential that you provide good ventilation for the Minotaur when it is operated in high bias mode. You may notice the cooling fan come on if ambient temperatures are high or ventilation is suboptimal. -
Page 9: Ventilation And Cabinet Temperature
The Minotaur should not be left running when not in use. Turning it off prolongs tube life and saves power. If the amplifier is used regularly, the vacuum tubes stabilize within minutes of turn-on. -

ONTROL The remote should work anywhere in the house, with no need to point it at the Minotaur. If it doesn’t, make sure that the antenna (packed in the same bag as the remote control) has been threaded onto the antenna input on the rear of the amplifier. -
Page 11: Toroidal Transformer
OISE SSUES The Minotaur produces exceptionally low noise, and if hum can be heard from the speaker, there is probably ground-current-induced noise (sometimes called a “ground loop”). With the volume control turned down and the amplifier on MUTE, disconnect all other equipment from the inputs. With the Minotaur operating by itself, there should be no noise even with the volume control turned fully clockwise. -
Page 12: Maintenance And Vacuum Tube Replacement
Although the lifetime of any particular tube is impossible to predict, vacuum tubes last much longer than most people think. Hopefully, it will be many years before you have to replace a tube in the Minotaur, as long as the amplifier is not left on continuously. - Page 13 5714 or a 12AU7, and the 5751, which can be replaced with a 12AX7. It is very unlikely that you will find a tube with less drift than the JJ 5751 supplied with the Minotaur (if you do, please let us know).
