Capacitor leakage - 57 Champ - advice please???

[Highway 49]

I’m just looking inside my ‘57 Custom Champ, changing tubes and trying unsuccessfully to track down a very annoying rattle, and I noticed what appears to be leakage from, what I assume to be, the capacitors - is that what this is? If so, is there likely to be any other/knock on damage or need for repair? And other thoughts or advice, other than don’t stick my fingers in there, would be welcome

the white stuff you see is silicone sealant to prevent those caps from wiggling lose and or vibrating , Take a look at the positive end of the caps if you see bumps on that end the cap is failing , these caps in your picture are Sprague Atoms caps ( brand name ) which are good quality , I always replace them with F&T caps of the same value as they are a little higher in quality and longevity . if your amp is a 57' the caps should be replaced if you notice your noise floor is getting louder.

Oh Yeah, be very Careful in the amp when the cap says 450 volts , it means 450 volts , with out mercy, leave servicing to a proper tech , or as you may regret it if your heart stops!

Thank you - that’s very reassuring - no bumps on the caps, and the noise floor is really low. I bought the amp secondhand and, having checked the serial number, was surprised it only dates from 2021 so I guess you wouldn’t expect to see too many things fail just yet.
The rattle is perplexing as everything I can see seems really tight - I guess that’s for another post. Thanks again for your help
