Hello to all. I purchased this clean as a whistle B&K 747B tester on the Bay about a year ago. Calibrated up perfectly.
The only thing it was missing was the cord and cap for testing tubes with the conductor on top. I don't know what the darn thing looks like. Does anyone know if one can be purchased or made? I thought I wouldn't need it, but my new passion is 1936 Zenith "Big Black Dial" radios which are filled with such tubes.
Thanks to all! Steve in Seattle
