5. Asennus

5.1 Tube Installation (if tubes are not pre-installed)

If the vacuum tubes are not pre-installed, carefully insert them into their respective sockets. Ensure correct orientation by aligning the pins with the socket holes. Apply gentle, even pressure until the tube is fully seated. Refer to the markings on the amplifier chassis for correct tube placement (e.g., KT88 for power tubes, smaller tubes for pre-amplifikaatio).

5.2 Kaiuttimien liitäntä

Connect your speakers to the appropriate binding posts on the rear panel. Ensure correct polarity (+ to + and - to -). The MT-45MK3 offers 4ohm and 8ohm speaker outputs. Connect your speakers to the terminals that match their impedance for optimal performance and safety.

5.3 Äänilähteen liitäntä

Connect your audio sources (CD player, DAC, streamer, etc.) to the RCA input jacks (Line 1, Line 2, or Line 3) on the rear panel using high-quality RCA cables.

5.4 Virtaliitäntä

Ennen virtajohdon kytkemistä varmista, että amplifier's power switch is in the OFF position. Connect the supplied power cord to the power inlet on the rear panel and then to a suitable wall outlet. Verify that the voltage-asetus päällä amplifier (if adjustable) matches your local power supply (220V).

7. Huolto

7.1 Puhdistus

7.2 Putken vaihto

Vacuum tubes have a finite lifespan and may need replacement over time. If you notice a degradation in sound quality, excessive noise, or a tube fails to light up, it may be time to replace them. Always replace tubes with the exact same type (KT88 for power tubes) and ensure they are matched for optimal performance. Consult a qualified technician for tube biasing if required after replacement.
