I would be cautious supporting half the amp weight by the heat sinks. They are held in place by the output driver screws into the backplane PCB PEM nuts.
Probably not an issue if being very careful, but that is not a structural bolted joint in any form.
Be cautious when mounting the backplane boards to the chassis.
The left board has the bias transistor offset slightly from the PCB hole and could damage the leads when trying to mount the p-clamp on the chassis standoff.
You may want to look into replacing that wall wart power supply with a dedicated power supply.
Most digital components respond very well to improved power supplies capable of supplying short high bursts of current, something wall warts typically do not provide.
Not a direct drop in replacement, but worth the effort. Same speaker outputs as used on the Model ONE amp.

Other than your bank account, you won’t regret a Model ONE.
After listening to that first song and ah-ha moment, audio nirvana sets in and any reservations completely disappear.

I’m just assembling the PCB’s on this project.
Kevin plans to assemble everything else and has an interesting new twist for the final look on his 700B.
Should be an interesting build to follow. Always great to have new ideas from people on this forum.
