Howdy. I would like to find a good home for my copy of a copy of the Ten Tec 670 cw keyer Operator Manual. I scored it from Vintage Manuals inc some years ago but somehow managed to modify my 670 to the point that the manual now only makes for a good mouse pad. If you got a 670 and would like to add this to your library, well, send me your address and I’ll huck it in the mail for you. Thanks.
