Sweet, some serious capacitance going on there. That thing is going to be a beast once you are done.

Fired it up with a variac and checked the ps output voltage, all good. Installed the driver board fuses and checked the bias, all good less than 5mv.
Put back in the rack and fired it up.
I am impressed. No noise, very musical and rock solid but very delicate at the same time. These modern capacitors are quite amazing. Definitely more tactile bass while cymbals slowly decay and recording room ambiance is enhanced. I could not be happier.
I had goosebumps with body rushes.....
I am out of town for the weekend and can't wait to get back and listen some more.
Thanks, I really want to get the XL600 freshened up. I love these big Haflers.
a side benefit to doing PS upgrades* in the XL 280s & 600s is they come from Hafler w/separate rectifiers & cap banks for each channel making the aforementioned* easier.

To the OP: did MC provide the wire to connect to the binding posts or did you reuse? In my XL280 I found subtle & not-so-subtle improvements using better/heavier wire for the above & PS caps to driver boards.

Really opened up with a powerful bottom end. Wrap-around 3d soundstage. I did not expect this upgrade to have such a positive impact on SQ. I am pleasantly surprised.
I replaced all of the wire running from the power supply to the driver boards and from the driver boards to the binding posts with 12 awg. Also, I replaced the 35 year old thermal paste under the MOFETs.
"Electronic music is human sound adapting to indulge technology, and for some, it feels like the signature sound of energy. New and abstract sounds over hypnotic rhythms can conjure vast soundscapes for escape, pleasure, and transcendence."
Well, after rewiring the power supply to driver boards, driver boards to speaker posts and replacing the thermal paste under the MOSFETS the amps mojo fell off. I had an oops o-carp moment.
250 hours later the mojo is back in spades. It took that long for everything to settle and burn in!
