I was reluctant myself, but now having not only taken the boards off and replaced multiple times (with everyone here’s assurances), it is a VERY easy process. Breaking the bond with the gaskets on the speaker being the biggest hurdle. Stay patient with gentle leverage and it will break free. Take photos of connections before. Take the boards somewhere locally, send them to Tarik, or to Marc Koval here in US. You will not be disappointed. Not nearly as much as when the boards fail suddenly (and perhaps catastrophically) from resistor burnout. These other tweaks IMHO will pale compared to this - If only for peace of mind against failure from resistor issues. And remember... your original post was for $400 upgrades...
I should put it out there... Bruce, do you offer such work?
