Stock T/R Relay Removal
The stock T/R relay is adjacent to the tuned input section as shown in Figure 3.14, and
held in-place by two screws, accessible from the top-side of the amplifier, through the RF
Deck. The RF choke shown in Figure 3.14 will be re-used.
Figure 3.14: Stock T/R Relay Prior to Removal
•
Carefully unsolder and remove the RF choke (it will be reinstalled later).
•
Remove the two screws holding the T/R relay.
•
Cut any wires where they connect to the relay and discard the stock T/R relay.
•
Remove any remnants of the original grey coaxial cables.
•
Clean all excess solder and residue from the ground posts and post feeding the tuned
input.
•
Remove the right side panel to complete this process.
