New LS 100 tube single-ended preamp from ModWright Instruments!

The design goal of the LS 100 was to pick up where the 9.0SE, our first product to be produced, over seven years ago, to the next level. We strove for improved sonics, aesthetics and functionality.

We Succeeded!

Single-ended design with 10 function remote control, (2) 6SN7 (Driver) and (1) 5AR4/GZ34 rectifier. Single gain/buffer stage, phase inverting, five standard inputs, one Monitor input and tape output, one Home Theater Bypass (HT/BP) input and three main sets of RCA outs.

Remote Control Functions Include:

• Power.
• Two remote trigger outputs.
• Selectable balance control, may be bypassed for cleaner signal path.
• Volume control.
• Mute.
• Input select.
• Monitor input select.

Preamp Functions Include:

• Upgrade slot for Optional in-board Phono stage.
• Built in headphone amp fed via tube driver stage.
• Home Theater Bypass.
• All pushbutton control, no toggle switches.

LS 100 Tube PHONO OPTION:

• One pair RCA inputs.
• Tube Design: (1)12AX7, (1)12AU7
• MC: Total gain = 63dB (including preamp stage)
• MM: 12AX7 replaced with 12AU7 = 48dB gain.
• Loading: 50, 100, 500, 1K, 47K, 100pf via internal dip switches.
  [USER/DEALER INSTALLABLE OPTION]

The LS 100 is built in the same size enclosure as the KWA 100 amplifier and has the same lines and aesthetics, including backlit logo. Taller enclosure (5”) allows for greater range of rectifier tubes to fit inside the enclosure.

Sonically, the LS 100 offers a greater control, ease, musicality and resolution, all perfectly balanced for the ideal musical experience. Frequency response is flat from 20Hz to well beyond 100Khz. Soundstage is extremely wide and detail and microdynamics co-exist with a tube warmth and natural musical presentation that must be experienced!
