Default Re: Vintage Radio and Phonograph cutter schematic

The only line capacitor I can see is the 0.01uF that's connected from the mains AC line to ground/chassis, if you replace that one you should replace it with a Y Class type.

The Candohm resistor is 4.5 ohms wire wound, so far as I can make out it's a dummy load for the output stage when the loudspeaker is disconnected, probably mounted on the chassis, you can replace it with a similar value wire wound resistor rated at 10 watts.
