Mod Transformer
Good thing I acquired mine when they were available. I know I saw one for
sale not long ago for $20, which is a good buy. they have a separate winding for the screen of the 813. This makes it easier to get 100% modulation, without having to match the screen dropping and shunt resistor resistor. 73, Colin K7FM |

Mod Transformer
And, they work great as a replacement transformer for the Viking/ B&W,
DX-100 series. Just the right size and winding ratio is close enough. I used one years ago in my Viking 1 that had been the backup transmitter at a local broadcast station. They had removed the original transformer and used a 200 pound boatanchor at the bottom of the rack mount. I got mine sans transformer and the ART-13 transformer fit perfectly. I miss that old rig. 73, Colin K7FM |
