Clean and Lubricate Pots in Tek 475
Ed: The A&B pots were designed to be modular. What I mean by this is that they are designed to fit together such that you can make a 1,2,3 section, or probably more, multiple pots out of the sections.

"Hi pitti_pu, I am puzzled by this part number. The 7L5 service manual confirms it is correct but there are no 155-0035 ICs. In fact there are no ICs starting with 155 in any of the Tek Semiconductor

EP53A Gain Set Adpater
I doubt that you will ever find a EP53A. Look for a TU-7 which is the EP53A and a pulser combined to cal the 535/545 scopes. Actually the TU-7 works for most 500 series scopes. How many plugins do you

475 Gain Issue
One quick thought. Check the 1 megohm input resistor R-39. That one could be open. Also check your calibrator square wave with the X10 probe. It is probably not square anymore because the 1 meg isn't

OT:"Search" not working?
Suddenly the "Search" function is working again. I did nothing between yesterday and today. Maybe the people at Yahoo did know something was wrong and finally fixed it. Thanks for the help. Bill
