with Upgraded MCaps, bias control, Ming Da’s European 120v transformers and much more!
The MC 34AB uses up to 12 tubes and packs a walloping 75 watts of power delivered by its
dual mono / power humpty configuration. Its flexible nature allows it to be used as an
integrated or basic amp in ultra linear or triode mode.
The new MD 75 was created special for the USA market to offer a high power amplifier at an
outstanding value. The MD 75 offers the ability to switch between EL34 / 6CA7 type tubes
and KT88 / 6550 tubes. Pacific Valve offers this amp in a variety of tube configurations
designed to meet budget and sound requirements. Pricing options are listed below, for
more information on the sound configurations, see “Tube Righteousness”.
A variety of circuit changes were done with original MC34AB to support the high bias current
of the KT88 / 6550 tube set. The bias controls are on top of the unit and bias is easily
adjusted. The outboard “Power Humpty” consisting of two upgraded oxygen free hand
wound copper transformers that connects to the amplifier via two high quality 8 pin cables.
The advantage of the Power Humpty is increased dynamic range, low noise and low end
response for the most demanding of speaker loads and music.
The MD75 can be used as an integrated amp or, with a flip of a switch, turn into a basic
amp for use with a preamp. The MD75 can also be placed in Triode mode, where its power
is reduced to 40 watts per channel or in ultralinear mode for the conservative 75 watts per
channel.
The MD75 comes with your choice of tube configurations, power humpty connector cords,
120V AC cord user manual and is shipped and serviced from Chicago, IL.

Bass: Deep wide bass without tube “mud” in the mid to lower bass. Mids:. Liquid, transparent and warm. Pushes midrange out into the
room where it blooms in the center stage. Does not carry midrange to the “nth” degree like 805 / 845 amps. Highly musical in this area
and addictive. Highs: The highs meld into the midrange nicely without upper midrange glare to screechy presentation. Presents an airy,
light high end. Dynamics: Dynamics held their own with difficult to drive speakers like electrostats or Maggies. Air around instruments:
Outstanding - correctly places instruments and vocalists in the sound stage with ambiance and air. Body and Weight: Placed significant
body around instruments as it suspended them in mid air. The weighting was above average and especially hefty with the Tung Sols.
Warm/Cold: Characteristically warm tube sound – but does not interfere with sound stage body, weight, resolution or transient
response. Imaging / Sound Stage: Varies widely with tube selection in order: Treasure, Genalex, EH, Tung Sol (The Treasure being the
best, Genalex close second, EH and Tung Sol tied) Resolution / Detail: Outstanding – as it ranks with other amps in this category of
acting like a “pass through” amplifier letting reviewers see the difference in DACs and CD players. Value: Very musical and powerful tube
amplifier with excellent resolution capabilities. You can select a variety of tube configurations where the amp changes its persona
“chameleon –like” depending on tube configurations. (See Tube Righteousness) Highly recommended.
