Tube substitutions/equivelents
I have a Yaesu FTDX 400 transmitter that I am restoring to operating
condition. In the tube list there is a "VR 150MT" called for, and on the chassis a Raytheon JANOA2WA installed. I have been unable to verify this substitution. Does anyone know if this is a correct replacement? |

The VR 150 MT is the Japanese designation. Les |

Dunno if the required series resistance is the same, but if the thing is regulating properly I wouldn't worry. --scott -- "C'est un Nagra. C'est suisse, et tres, tres precis." |
