The Little Dot MK4 SE is a special edition of the MK4 tube amp and replaces the MK4's driver tubes with M8100/CV4010 driver tubes and 6H30PI gold-pin power tubes. As with the MK4, it comes in an aluminum chassis, internal jumper, and double gain switches. The SE improves on the MK4 with a nuetrik headphone jack, premium circuit components in key signal path locations, and premium RCA connectors.
