Looking like you're making some progress.
Also with your (and others) enthusiasm for the Staccato opamps, I may have to try those at some point. Seems like they do all the right things with none of the downsides. I think the long and skinny series would fit on my amp with no super-sized risers. Since the small 10uf caps were moved out of the way for clarity caps, they likely could fit. Downside is they're more $$ even than the Sparkos. Ooof.
The bad news, you can't mount Staccato op-amp's correctly on a A5 circuit board without extenders.
Mounting without extenders!


This is where I would mount Staccato op-amp's onto their zip tie mounts.

Even though your chassis is overall larger, I would still suggest using extenders for both Staccato’s
op-amps. For multiple reasons, I would mount both op-amps on the right side of chassis.
1.) Since Staccato op-amps operate in class A, I would suggest isolating their heat dissipation away from your main circuit board. Less heat near any circuit board, the better.
2.)With the flexibility of the extenders, your able to position the op-amp’s further away from your upgraded capacitors and their wire leads. Locating the extender / op-amps on the right side of chassis, you could screw in a couple of black zip tie mounts, on the right side wall of chassis. Wrapping the zip tie’s between the wires of extenders, to the side wall of the zip tie mount is very easy and worthwhile step. Plus, having them both in the same position would have more symmetry in pairs.
I have another little tip, I’ll be glad to share, if decide to purchase a pair.
3.) You still have the flexibility of swapping out different manufactured op-amps this way too.
