Restored 1950’s Magnecord M33 Studio Grade Rebuild Pair w/ Original Carry Case

Stuck with a sterile sound? Sounds like you need some crunchy, vintage-but-restored channel strips to color it up

Don’t spend more on a REDD47, Manley, or Ampex when you can have a fine-tuned, hand-wired preamp with vintage transformers and a unique character for less

These early 1950’s Magnecord M33 preamps have been fully rebuilt with many essential studio features added

These mount right into a 2U rack space with the included rack ear extensions 

Front panel from left to right 

Hi-Z in, 20db Pad, Mic/Hi-Z input select, power switch/gain control, magic eye indicator, Mag-Auge switch, T-Pad output attenuator, output polarity switch, power indicator

On the back

IEC mains in, 1/2A fuse, magic eye trim pot, mic in, line out. Original tube locations (12AX7, 12AU7, 6X4) remain the same.

The “Mag-Auge” switch allows you to turn the magic eye on or off when desired, as to preserve the phosphor coating on the 6E5. A trim pot on the back allows you to adjust the magic eye for your recording levels. They are currently set to +4dbu.

With improved filtering, better shielding, and DC filaments, these achieve a -120dbu EIN figure with +70dbu of total gain.

0.12% THD+N  @ 1khz, @ +4dbu. Using the T-Pad output attenuator, you can vary THD+N from approximately 0.12% to 0.7%

A variety of NEC, Tung-Sol, Sylvania, & RCA tubes have all been tested with a TV-7

Vintage Triad & Thordarson transformers
