Ok, the 5335A is now working. One of the group members kindly came up with the needed cables and that led me to the original problem with the unit. A bad input fet, 1855-0300, Q5. The best I could find was around $20 for the actual part. I was able to determine the charistics of this part from the voltage readings in the manual and came up with a good replacement, a 2N5485 works great and is readly available for pennies.

The ebay seller listed the unit showing intact calibration stickers leaving one to believe it was a complete working unit at one time. This could not be the case seeing that the cables were missing. This seller is located in Chatsworth, Ca. so beware. While the seller did state correctly that the unit did not work, I feel it was misleading to have the calibration stickers on the case. My thanks to the group for the assistance. Regards, Tom --- In hp_agilent_equipment@..., "Tom Miller" <tmiller11147@...> wrote:
