    MARSHALL TRANSFORMERS                

    * We order transformers per order, please allow 7-10 business days for delivery *

    Make sure you know what transformer is right for you. Installation of the wrong transformer can severely damage an amp.
    The amount of power running thru a transformer is extremely dangerous. Always have installation done by a qualified technician.
  • ALWAYS MAKE SURE THE AMP IS NOT PLUGGED IN BEFORE ATTEMPTING REPAIR!
  • TUBE AMPS PRODUCE DANGEROUS AMOUNTS OF CURRENT
  • CAPACITORS CAN STORE ELECTRICITY AFTER THE AMP IS OFF
  • MAKE SURE CAPACITORS ARE DRAINED BEFORE ATTEMPTING REPAIRS

    * * IF YOU ARE NOT SURE SEEK OUT A QUALIFIED TECHNICIAN, HE'S A LOT CHEAPER THAN A FUNERAL! * *
