I have this Lanzar amp with a heavily damaged power supply that I’m rebuilding and I haven’t run across too many drive circuits with ceramic caps across the drivers. I have one that was causing a short across one of my NPN drivers and I need to replace it.
What are they doing in the circuit? How important is it that I get the value correct? Can I substitute a different style cap in it's place? This is the first one that I’ve actually found that was bad in a circuit since working on car amplifiers. So I’m kind of a dummy on this one.
The bands or Orange, Black, Brown which according to an online calculator is 300pf. Unless I read them backwards and it’s brown, black, orange, then it would be 10nf.
Thanks,
David

The diagrams for a similar amp have them as 104P (0.1uf).
Did you pull the one in the board to read its value?

Yes. I did. It reads .1uf. Wasn’t sure I could trust that reading considering the other one was bad. I’ll just go back with a .1uf ceramic disk capacitor because that’s what I have in stock. That should fine, correct?
