Thanks for the replies. Rob got back to me and told me I can send it back if I want and they’ll do it, but then I told him I can just add the components myself to save hassle if it’s just a cap and resistor. He said a 680Ohm resistor and a 220uF cap. He then said if I don’t have those he can send me them, that’s nice of him.
The closest I can get is 470+220Ohm in series to make 690Ohm but I can’t actually find my capacitors I had so I might just be best off getting him to send them and waiting.
