The Second Doctor's classic The Enemy Of The World (1967) and The Web Of Fear (1968) were among those traced to the TV relay station.
The latter features the Yeti and introduces Alistair Lethbridge-Stewart, better known to audiences as The Brigadier. Digitally remastered versions will be made available on iTunes and DVD.
Phillip Morris, the director of Television International Enterprises Archive, unearthed the shows by looking up the records of overseas shipments of tapes.
Mr Morris said: "I remember wiping the dust off the masking tape on the canisters and my heart missed a beat as I saw the words Doctor Who.
"When I read the story code, I realised I'd found something pretty special."
