In case anyone is interested, I've just put these up.

They show the insides of the amp.

Please don't visit more than once or twice each; I don't want my
bandwidth allocation eaten up.

Very nice, especially for the price. I like the way they bothered to put the
component value prints on the pcb (for manual board stuffing?) and they
bothered to sleeve the wire of the two yellow caps but I wonder why they
floating so high ;-) maybe if its not wave soldered then it could be some
assembly workers overheated short leads with manual soldering :-) (there is
always a reason why) The pcb appears good grade as well. What sort of info
comes with the amp?

That looks like a stereo jobbie in which case what one is the mains
trannie and the O/P as one would expect two the same, unless their
contained in the large can at the back?....

It is stereo. The Huge toroidal in the middle is the mains xformer.
There are (obviously, duhhh) 2 o/p xformers. One I left covered by the
can, and the other I "uncanned" and you can see in the photos. It's
not toroidal. They both sit near the back.

As for the heat shrink on the yellow caps, the reason it doesn't reach down
to the PCB is that I lifted it up. I was trying to check whether there was
continuity between those leads and some other points in the circuit. They
were originally right down to the PCB.
