Understanding the specific parts is crucial for any restoration or repair. The N7000's primary passive components are its capacitor and inductor. According to vintage JBL literature, the part number for the is #10460 , which corresponds to a 1.5 μF (microfarad) unit. For the inductor , the schematic calls for a coil of 0.6 mH (millihenry) . It is important to note that JBL used different part numbers for the inductor in the standard N7000 ( #13219P or #16265 ) and the 16-ohm version ( #10421 ), with measured values coming in around 0.57 mH and 0.5 mH respectively.
If you are looking at an original JBL N7000 schematic or looking inside a physical unit, you will typically find the following component profiles: Inductors (Coils)

Original JBL inductors rarely go bad unless subjected to catastrophic amplifier failure. Keep the original inductors unless the windings are visibly burned or shorted.
Wire a high-power 8-ohm (or 16-ohm) L-pad in series with the positive leg of the high-pass output to give you complete control over your tweeter's volume level. For the inductor , the schematic calls for a coil of 0
The variable level controls often accumulate oxidation over decades, causing scratchy sound or signal dropouts. Use a high-quality electronic contact cleaner (like DeoxIT) to restore smooth operation.
Vintage paper-in-oil and electrolytic capacitors degrade over decades. They suffer from dielectric breakdown, causing their capacitance to rise and their Equivalent Series Resistance (ESR) to spike. This shifts the crossover point away from 7 kHz, potentially endangering your tweeters or causing a hollow, muddy high-end response. Step 2: Choosing Replacement Components
