Anyone in the UK got one of these - I'll happily pay a reasonable charge for it (or even a slightly unreasonable one).
It *must* be carbon composition or carbon ceramic, as it is being used in a circuit with high pulse currents which would destroy a film resistor.
I could buy some from the USA, but the cheapest I've been able to find would have cost me about £34 or more including postage etc. Some were MOQ of 300, which doesn't make sense for a (probably) one off repair.
A 1W part probably won't fit. The space into which it must fit allows for a body diameter no greater than 4.5mm maximum (original is 3mm diameter), and length is 10mm (a couple of extra mms won't hurt here).
