Tektronix 465B Focus Problem
The traces on my 465B scope are bright but a bit out of focus...I have
heard of resistor problems in the focus control voltage divider in other models that have caused this same problem. I checked the CRT schematic and noticed the resistors in question are in a resistor network of 4 resistors. Any thoughts on this would be helpful. Thanks Mike Miller Kansas City |

Tektronix 465B Focus Problem
The focus control seems to function correctly, but you can't quite get
the trace clear and sharp. |
