Re: TEK 547 no trace

Hello Rob,
Now that you mentioned the very early S/N we can forget about the issue with C562.
You might see what the 547 does in XY mode, Horizontal mode in EXT. No input signals needed if you beware of too bright dot (de-focusing makes it safer).
The dot can remain visible now, with position listening to Hor Pos, or can show the same fault as in sweep mode. In either case you narrow down where to search the fault.
