Yamaha XH150 repair advice

The PA amp at my Church has gone kaput (technical term!) and I've used my v limited knowledge to confirm the internal fuses are intact.

I can see some obvious damage on the board (see pic) but clearly there could be more.

Can I ask if anyone has a recommendation for someone who could repair (North London/Herts area ideally) and if it is likely to be economically viable to do so.

It drives 5/6 small monitor speakers for voice and music at weddings and general services, it's a large space but volume requirements are modest.

Any ideas for potential replacement also appreciated, will need XLR inputs.

Something like this Crown will do the job https://www.bax-shop.co.uk/amplifier...0PLA%20-%20SSC

Hi Martyn, I got one of these, (as it will drive 2 pairs of speakers) going into 4 little Wharfedale Diamond speakers for my daughter's hairdresser/sunbed shop, and it works very well.

But she wanted the same thing coming out of all the speakers (which were each sited in different rooms), so to avoid her having left channel going into two of the rooms and right channel going into the other two, I put one of these between the source and the amplifier - also worked very well.

This is double what I paid 6 months ago, so if you went in this direction it might be worth shopping around.
