I looked in a tube substitution book, and there was no replacement for a 3A4.
Could it be the tube is newer then the tester? You could Google "testing a 3A4 in a B&K 667", or see if there are any updated charts. Could be it wasn't made to test one. Contact B&K. Hopefully someone else one here can help. |
