  • Notes

  • The DX Television VT-300 is a variable autotransformer (variac style) rated at 60-150 VAC output with 60-110 VAC input. The output voltage is metered using a lighted meter. The supply is fused on the input side with the fuse mounted on the side and accessible via a little flap door.  The supply is rated at 300 watts.

    The variable control has an integrated off switch when fully counter clock wise.  In testing, the supply actually could be turned down to about 30 volts before cutoff. Although DX Television Limited is not listed by RMorg, the supply is believed to be a product of DX Antenna Limited of Japan.  The red stripe on the meter is marked at 100 VAC (Standard voltage in Japan) and the power plug and power outlet were manufactured in Japan.
