Thanks, got the recommended ones from RS yesterday and fitted them, and it still works! That's always a good bonus!

One resistor, the cracked one, measures 37 Ohms, the other 3 low, but within 4 Ohms of 47 Ohms. What effect would the 37 Ohms one have been having had I left it in or was unaware? Thanks again, stay careful!!
