Little Dot MK II MK 2 hifi headphone pre-amplifier 6J1+6N6 assembled tube amplifier
An SEPP (single-ended push pull) OTL circuit operating in Class-A, the Little Dot MK II greatly increases sound quality, dynamic range, output impedance, and harmonic distortion over the celebrated Little Dot II++.
The Little Dot MK II now also provides gain control of 3, 5, and 10 via internal DIP switches for fine-tuning so you can maximize synergy with almost any headphone you have, whether it be 32 ohms or 600!
The Little Dot MK II also gains the driver tube-rolling options from the rest of the MK-series with the ability to roll 6JI, WE403A/B, GE5654, M8100, CV4010, EF95, etc at its factory jumper setting, and with jumper pins shorted, EF92, CV131, and all equivalents and drop-in replacements!
