Maker’s warranty is always from INITIAL sales date. They usually only require a copy of the Original Sales Receipt to establish warranty start date.
Invoice would need to say ’New’ or ’Open Box’ to qualify for a ’fresh start’ of a maker’s full warranty.
IF invoice says ’used’, see below
It could have been in a warehouse for years, so serial # is irrelevant.
However, IF unit was registered with maker by original buyer, a copy of Maker’s email acknowledgement (to original buyer) with date/serial # might be enough, not sure. You could write maker, ask if serial # -------- is registered in their data.
’Remaining Warranty’ for a ’used’ unit:
1. does the maker (not the dealer) allow warranty transfer?
2. Copy of ------? establishing initial sales receipt would be needed.
3. Sometimes there is a maker’s process of confirmation (initial buyer/seller paperwork or online form needed to make the transfer of warranty).
4. Existing Aftermarket Warranty: some are not, some are transferrable, usually they require their process to be completed.
5. You can sometimes find/buy a warranty for used electronic equipment. You pick the $ range of coverage, the price reflects that.
i.e. for my Blackbird 12.5" Tonearm from Russia, I bought a 3 year Square Trade warranty ' 3/5/2020 to 3/5/2023 (hmm just ended) up to item's purchase price ($1,000.) for $109.
lucky I did, it needed it's wires replaced October 2021, copy of repair invoice from VAS got me full re-imbursement (cost far exceeded warranty price of $109.)
