My mistake - earlier I said 2.00 inches wide; it's actually 1.75". Lam stack is 1.00" but the bobbin flanges are 0.375" each side. I have corrected my earlier post - sorry for the error!
In either case, the planned location can work as long as the outer flange extends past the aluminum chassis pate.

The data sheet says 2" wide, including the bobbin. Mounting holes are 2.812" apart (full flange width 3.312"). You could squeeze it in the space, but you couldn't align the centers.

<sigh> yeah, you're right. I did not allow for an extra margin in bobbin sizing. The one behind my head on the shelf is the old style, layer wound without bobbin - my caliper says 1.874" wide.fullheadofnothing said:
It looks to me like you could fit it on the input jack side but would have to move the power switch and IEC socket on the other side.
So it would be possible if both were perfectly aligned with the PS exactly in between.
This wasn't my planning. I hoped to be fine with both sticking out an inch on the front of the PSU.
So in the end, it's not going to work without moving the on/off and IEC socket.
Edit; So i'm probably just moving to a toggle switch that mounts behind the PS.
I can cut off the mounting part off the choke that comes in front of the power inlet. And that side is then mounted from underneath using the hole left by the current switch.

There's a lot of info on this topic. I've searched extensively before i asked my current question.
I'm planning on Ansar film cap because a 220uf is only 60d * 82mmL (and is custom, so lower capacitance lowers the diameter).
Found confirmation that probably going bigger = better; http://bottlehead.com/smf/index.php?topic=6131.msg59443#msg59443
