  • I tested these test sets from 1970 to 1973
    at Whiteleys in the Set room with Keith Williams when we where part of the Inspection
    Team led by manager Cyril Lane. I left Whiteleys in October 73 to join Post office
    Telephones has a lineman then used these test sets to test lines in and out of the
    Exchanges. Stuart Mallinder

  • I left school, aged 16, in 1974 and worked for Whiteley Electrical Radio Co Ltd in Mansfield, Notts. I used to build and test these units. We made hundreds of them in the mid 70's. Slightly updated from the early model shown, however, clearly recognizable.

  • I have an example of this test set. Rescued, slightly damaged, from a skip.
    It uses a B101 battery (67 Volts).

  • was the standard test kit in rural exchanges. it was connected to exchange battery , exchange ringing generator though it had hand operated generator built in and a telephone set. the test clips were generally connected to the main distribution frame. this was the point where testing to line i.e. toward the subscriber was performed.tests available were insulation . earth or negative contact and condenser kick .

  • I mounted one of these on a trolley and used it as portable test desk. I believe in small exchanges they were fixed to a wall and were the only test set in such exchanges.
