I'm building a digital power base for a Scalextric slot car track using the schema provided here (you might have to click the "Powerbase Circuit" tab).
Now, my question is, what type of capacitors should be used for C7 and C8 (the right-most ones next to U3 & U4). What is said about the caps in the text is only "Output protection is provided by suppression capacitors C7 & C8", but nothing about their type.
At my local electronics shop, the only bipolar capacitors they had was 1,5uF of the following type: "Visaton elko glatt 1,5uF 10%". It also reads "For high quality speaker networks". See this link for a pic.
Can I use these caps for this purpose or should I get another type with correct rating (of 1uF)? In that case, which type should I use?
