Hi,
For sale is a pair of input transformer, Cinemag CMOQ-4LPC.
Preferably shipped to Europe, but rest of world is possible.
60 euros for the pair, shipping at cost.

Probably a stupid question, and the wrong place to ask, but what is exactly the difference between an input and output transformer? As long as impedances 'match'..?
This is a fair question. Generally the assumption with an input transformer is that the signal levels are smaller, therefore the transformer itself can be a fair bit smaller. It would be totally OK to design a 1:1 input transformer and just assume that it will see 5V of signal at maximum.
For an output transformer, one should presume that the levels will be higher, so you'll often see things designed to allow for ~10V at the output. That's physically just a bigger transformer in general. There's also definitely the possibility that a line out transformer may need to be designed with an air gap, and that isn't something you're going to find with an input transformer (though maybe someone will know of one example where that is the case, but I haven't seen it).
