It depends on the manufacturer. Some manufacturers (Madrigal, and its subsidiaries, for example) extend the warranty regardless of who you acquired the equipment from.
Others (like Sonic Frontiers) require the purchase of used equipment to be from an authorized dealer to extend the warranty.
Others extend the warranty ONLY to the first purchaser of the equipment when it is purchased new and from an authorized dealer.
The ONLY way to know is to contact the manufacturer and ask.
