Reply To: Stevens tester

[Dave Willacy]

Well this is  an old post but I happen to have a Stevens tester with power supply on the bench for repair.  I am looking for a  definitive answer to What is the correct voltage output for the auxiliary power supply?  Does some one have one that can measure it?  Any specs that state DC output?  Anecdotally the manual says to hook up the test box to 6 v.  Anecdotally I have heard folks measured 8V.  Given that  the current specs in the manual for each coil assumes a fixed voltage of a certain value it makes sense to get it right.  The old selenium rectifier in them used to drop a ton of voltage.  A modern silicon bridge works great but yields too high a voltage. 20 plus.
