Re: TOS original broadcast tapes found - need player
Tapes which have aged badly can be restored by 'baking', but the result's usually only good for a single 'salvage' play. The only colour copies of quite a few early '70s Doctor Who episodes were recovered from US stations and saved this way, so there's quite a bit of info on the techniques used on sites covering the missing Who episodes.
