looking for a fisher 800c output transformer

hello,
does anyone have pile of 800c parts or an 800c in a pile?
I have an 800c in the UK that is a lovely thing but has been a) bodged and b) dropped. We are working through it but need the speaker selector knob, 3 sliders, but mainly an output transformer... T991-116-1C
I'm in the UK but happy to sort out a way of getting it here from the US...
thanks!
