Copper Band in a Cross-Over Choke??
John:
Same issue, only more so. A choke, typically, a hot source for stray magnetic fields and an air choke would generate those fields in a fairly predictable manner such that a "flux damper" of a specific configuration might be just the ticket. Tha bean counters have me amplifier real estate too expensive to allow extra space for isolation. This may be an accommodation.
