We are glad to announce that the MP-301 MK3 2013 deluxe version is in stock now. 

Here is a brief list of the improvements.

1. The whole PCB board is gold plated for better signal purity. Unique Design!

2. The total power filtering capacitance is increased again to further lower noise floor.

3. High quality power switch. Made in Japan by ALPS.

4. Higher quality input and output selection switches. 

5. Lower tolerance ALPS volume control.

6. Higher quality headphone Jack.

6L6 power tube is recommended for headphone users to obtain the quietest background.

The MP-301 series is the most popular Musical Paradise tube amp which was first released in 2008. In 2011, the MK2 was introduced to the market with many improvements. The enhancement process has never been stopped. Today, we want to introduce you the new MP-301 MK3, the third generation of the MP-301 series. After collecting large amount of users' feedback and recommendation during the past years, we bring the MP-301 series to a new high performance level.

Here is the list of improvements:

1. The power transformer is upgraded. The EI core is 30% larger to lower the working temperature. The potting material is upgraded to higher grade epoxy to improve the strength and heat resistance. More precise user configurable input voltages: 110V, 120V, 220V, 240V.
2. Add KT88 and 6550 power tube support.
3. The case construction is improved to be stronger and much easier to access when service or upgrade is needed. Since the steel is thicker, and the case is a bit wider, the background hum is much lower than the MK2 version when using low impedance headphones. It is hardly noticeable now.
4. The circuit is improved to further lower distortion and increase the stability when using some lower quality power tubes.
5. High quality screw-in connectors are used on the PCB boards, so the PCB can be removed much easier without soldering when service or upgrade is required.
6. Output transformers are improved with better construction to improve low frequency response.
7. Total power supply filtering capacitance is increased by 60uf to further lower background noise.

Features:

• One amplifier supports 6L6 (6P3P), KT66, 5881, EL34, KT77, KT88 and 6550.
