Re: Johnson Viking Valiant 2 - voltages


 

Johnson Valiant AC Line Fuse blowing????????????????

Our experience led us to the conclusion that in the case where AC line fuses continued to fail ( with all tubes removed), the issue was with the Valiant HV transformer.
?? Over the time we rebuilt Valiant II units, we experienced several HV transformer failures, almost always shorted windings in the AC primary windings.
?? This experience led us to install a separate AC line fuse for the HV transformer, the fuse located in place of the interconnect socket.

I hope you stumble across what's wrong. There's an EF Johnson mailing list. It
isn't very active, much like this list, but it's another place to see if you can
get help. More information here:



Click on directory of lists and find the one for Johnson, and fill in your
information.
