    This is an Isocore transformer specially designed to prevent electrolysis taking place between the primary winding and the core. The winding and laminations are sealed into a streamlined metal can with which they have no electrical contact. This transformer is designed to operate with speakers having a voice coil impedance of 2 ohms.  For 6BV7, 6K6, 6M5, 41, AL2, E443H, EBL1 & EL33 see type CBG64. For 6AQ5, 6BW6 & 25A6 see type CBG81.
