Hi Joe,
That doesn't look too bad under all the grime.
I have an RP25A which was in a similar condition to yours but not working. I traced this to the the volume control/switch which was changed to a modern part thanks to a post from Mark Hennessy which got it working. There was a wave band switching issue which was cured by a squirt of cleaner. The wiper on one of the variable resistors on the audio board must have been tarnished and wasn't making good contact with the track which was cured by adjusting it from side to side.
Lastly, it has the occasional bad day with the audio board connector. Nothing new there then!
Regards
