        The attached file is from the fifth edition of the NAB Engineering
Handbook, 1963.
        I used the lower part as the basis for my ringer, and doubled up on the
2N256's to get more currant. ( I had to ring big old phones reliably. If it
doesn't ring when it is supposed to, the sound man is in trouble!)
        Later I installed a power transformer and rectifier so it could be run off
        Also, you might do a search on the net for Don Britton Enterprises, 7906
Santa Monica Blvd. Hollywood CA, who were suppliers of various telephone
circuits and stuff about thirty years ago.
