| Standard RA17 front panel layout. The model suffix 'L' probably stands for 'Low noise', L versions having a cascode first RF amplifier stage using an ECC189 (CV5331) double triode. |
| Modified power supply: In this unit the Plessey mains connector has been replaced by a filtered IEC connector. The voltage selector has been removed and replaced by a switched IEC outlet for the LF adapter. The mains transformer is shown wired for 230V (orange and grey wires). |
| Socket replacement: Here the Burndep connectors used for antenna input and IF output have been replaced by SO239 sockets. At the IF outputs, drillings for standard 4-hole mounting SO239 sockets were already present. The antenna socket is secured by a nut. |
