There is space for much more capacitance. 22 000uF would be an upgrade worth its salt. Some rearrangement may be necessary.

This might not be so...
The PCB wires are not "magic" and looking at the layout, the negative is quite long and also includes a jumber.
I would mount the caps close to the rectifier, maybe dismount the rectifier and place it close to both caps. And then wires directly to loads...
I wouldn't mind betting that the original filter caps are still in spec. I've found in the past that high value good quality filter caps last extremely well. Not so with small value coupling caps. They are definitely a candidate for replacement.
thanks for your advice, I'm not doing anything that makes me end up with a dead amp , if I can't find direct replacements with 12 or 15000uf I'll leave it , just wanted to try my new dessolder station 🙂

found ones that will fit straight in but bloody expensive

I think there's a not too small chance of deteriorating your device by swapping those 'lytics that don't show any sign of damage or malfunction for dubious ones from ePay.
