Speaking specifically of power supply 'lytics, I am of the opinion that they should be replaced as a matter of maintenance and safety. Since they are not in the audio signal path, they will not affect the quietness of the amp - tube amps in particurlar. By quietness, I mean the amount of hiss/noise from the amp when its hooked up to a set of speakers. For the safety and operational reasons, this is a prudent thing, IMHO.

Other 'lytics can be found in the audio signal path, however, unless there is a large voltage across their terminals during operation, in which case, I would consider them part of the maintenance of the amp.

Generally, audio chain caps are not the first place to look for noise from the amp - tubes,transistors, IC/chips are the first especially in older gear.

To say again: Replacing large power supply 'lytics is a good idea for safety reasons alone. But there is no hard-and-fast rule on this as you can see from the multitude of posts on the subject here at the AA.

Hope that helps.

Cheers,

David
