Laney AOR 100 Coupling Capacitor Value

Post by 760Joe »

The ceramic Capacitor in c20 was bent over and sort of melted into the resistor next to it (R39) and the capacitor's insulation was falling off so I thought I would swap that out while I was doing all the electrolytic capacitors. I couldn't read the value on the existing component. The schematic lists a 47pf capacitor for c20. The larger ceramic capacitor is what was in that location physically. The capacitor on the right is the 47pf capacitor I got for a replacement. Now looking at it out I see 47 N. Is that nanofarad? Should I get a 47nf or put in what the schematic says?

47nF would mute the signal there. Is this the model with an impedance selector switch or does it have discreet speaker outs for each impedance? I have my own ripped schem of one here somewhere but IIRC the two are different.

I suspect "N" is a tolerance value, not meant to be "nano".

Thanks everyone for the input. I went with the 47pf.

This one has a selector switch.
