Default Whistling Roberts R200

My car boot bargain has shown it is always wise to look a gift horse in the mouth.

I have some reception but it is quite weak and I get a lot of whistling. This is the earlier OC44/45 model which I believe does whistle a bit but I expect a few capacitors are not doing their job. There are a mix of electrolytics and some moulded capacitors that look possible culprits. Any advice on which ones normally need to be replaced?

Then do I remove the existing capacitors and substitute new ones or try to leave them physically in place and solder new ones underneath?

I plan to re-align the set when I'm done - is it a 465KHz IF?
