Not really TEA, but I've just been given a Denon AVC X8500H to repair. It has the biggest transformer I have ever seen inside a commercial device.
McBryce.
(for info, the primary side of the PSU shorted for some reason, haven't found out why just yet).
That's a baby. Check out the back of a Crown DC300A:

There's a lump inside the case as deep as that cover on the back of the transformer, plus mountings and terminals. The transformer winding is easily a foot deep in total.
Edited to add: I can testify from personal experience of humping those babies into and out of racks that they also weigh a freaking metric ton. (OK,I exaggerate it's a
mere 18.2 kg) I've manhandled them solo in the past, but with a bath chair and a hernia beckoning I think I'd leave one of these to a couple of young 'uns nowadays.
