  • Page 3: Introduction & General Notes

    INTRODUCTION THANK YOU!... for choosing the Manley Laboratories "The 300B Preamplifier". Handcrafted in Chino, CA, the Neo-Classic 300B Preamplifier uses beautiful sounding parts in a clever and clean signal path. This Preamp features the 300B direct heated triode as the line and headphone driver. The 300B is typically used in low power amplifiers as a power tube. These 300B-based amps generally deliver 5 to 9 watts single-ended and cost from $3,000 to over $100,000! Some of these amps sound very nice coupled with efficient speakers.

    SLO-BLO fuse is one reason...) If you have no idea why a fuse might have just blown on its own, you might want to consult with Manley Labs or your dealer for further advice as something Very Bad might have occured, like the power transformer might have decided to retire early.

  • Page 5: Connecting Your Preamplifier

    CONNECTING YOUR PREAMPLIFIER Setting up your preamplifier is rather easy. 1. Please refer to page 8 for an illustration of the back of the preamplifier. 2. Connect the RCA outputs to the input of your power amplifiers when they are off. 3.

    HEADPHONES HEADPHONES HEADPHONES HEADPHONES HEADPHONES TAPE TUNER VIDEO A - INPUT SELECT - 5 Position switch for input selection. Each input is electrically identical. The RECORD OUT directly follows this switch. There is no buffer amp to isolate the effects of loading and cable capacitance so we recommend disconnecting any interconnect cables from the RECORD OUT if you are not recording.

    A - HEADPHONE IMPEDANCE SWITCH - You should set this switch to best match your headphones. You may have to look at the specification sheet to get the value in ohms. If using two sets of phones divide that number in 2. If you don't have this info then pick the setting that sounds best - no harm will be done.
