Hello. I am in my building infancy as im getting into electronics building and have a question as i need to buy some replacement parts for a circuit i am trying to replicate. the circuit has ceramic and film capacitors that i am not able to measure as i cannot remove them but they seem to have numbers printed on them and i was wondering if it is possible to identify their values this way? some of them have underlined and black tips. here is a photo of the circuit in question and the ceramic and filter caps labeled along with the numbers printed amongst them. thanks for the help
