Quick question.
Are these 2 types of relays interchangeable in use if the amp rating and operating voltage matches?

I need a 5 A soft start power supply relay and thinking of cannabilising the part from an old amp board .
I intend to use this circuit from Elliot as i have most of the parts . circuit attached.
cheers

The soft start relay is fitted to the Mains side of the transformer.
It must be rated for Mains duty.
The current rating will be the Vac current rating. A 5Aac rating @ 240Vac is adequate.

The speaker relay is very different.
It must have a suitable current rating @ Vdc.
