Sony TA-VE215 sound cutting
 

Hello, I'm very sorry for the repost but I'm having a lot of trouble with this amp.

I have a Sony TA-VE215 amplifier and have a problem with the speakers cutting out. They work for a while and then a switching sound occurs, cutting the sound from the speakers. I have provided a link below which explains that there is apparently a connection to the relay that has been cracked and it needs re-soldering. May I ask how I would go about doing so.
