Texas Star DX 667V CW Transmitter To AMP Conversion

1. Unsolder the wire from the key jack on the rear panel near the fuse holders.
2. Locate the two standing capacitors (15pf and 33pf) near the relay and RF choke. Unsolder and remove the wire from the tops of the capacitors. Separate and remove the 33pf capacitor leaving the 15pf in place. Resolder the standing end of the 15pf capacitor to the adjacent pad on the board. This pad also connects to a wire from the rear panel S0239 connector (Radio).
3.

Remove the 33 ohm resistor (ora-ora-blk) (and wire if present) located directly behind the relay. This resistor connects a RF choke to the oscillator board.

NOTE: Some units may only have a wire without a 33 ohm resistor soldered to this point. In that case remove the wire.

4. Unsolder and remove the large yellow capacitor (marked 2200K) connecting the center of the blue pot to the oscillator board. Do not remove the resistor connected to the pot.
5. Locate the white block resistor and RF choke behind the meter. Unsolder and remove the 10 ohm resistor (brown-blk-blk) from the top of the 30K resistor (ora-blk-ora) beside the RF choke.
6. Locate the wire soldered to Pin 1 of the Power switch (red lens). Unsolder the grounded end of this wire, and solder it to the 10 ohm 2 watt resistor (brn-blk-blk) located directly under Pin 1 of the Power switch (red lens).
7. Unsolder and remove the oscillator board if desired.
