What should I check when buying a used Crown Macro-Tech MA 9000i?
Confirm the channel output and that the global power supply is functioning correctly for your region. Check that the Ethernet networking port and onboard monitoring are operational, as faults there can be costly to fix. Inspect the chassis for road wear consistent with touring use.
