AF Test Adapter Schematic
Note!
Because of the bridge audio amplifier circuit used in the VX-800, it is necessry to construct and use
a simple audio load test adapter as shown in the schematic diagram above, when conducting
receiver alignment steps.
Do not connect either side of the speaker leads to chassis "ground."
