Jeff: The P/N 070-1332-00 is the manual you want. I see a pdf copy on Tekwiki at "http://w140.com/tekwiki/wiki/Main_Page". Then go to the 475 listing following the "400 Series Scopes" to the 475. Clic

Jeff: Don't be mislead slightly by the removal of the 465 vertical preamp board in the eevblog tear down. The 475 vertical board differs in that the attenuator switches and BNC front panel connectors

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.

You are describing the "A & B" (Allen Bradly) pots. I just got through going completely through my 475 after years of putting up with attenuator "leaf springs" not making good contact and the vertical

"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

Eric I just went through Calibration of my 576 using the -01 version of the manual about a month ago. I don't remember which scope I used but it was probably my Tek 475 because it was on the bench at

I have one of these 7A18 with the offset pot in place of the trace identify button. But mine has an "option 6" label on the top. It also has an additional position on the input switch. Instead of the

John: I have 4 of these P6201 probes and in all R298 runs HOT! When I have the covers off of the Amplifier Box for adjusting and every time I touch R298 accidentally I jump a foot because of the temp

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

Dave: After researching the source of this 7104 manual FEB 1989 I see that I did buy it from QSERVICE Nikolaos Kapetanakis for $US 9.49. So I don't feel good at all in sending this PDF to anyone and/o

Dennis: I know you are not looking for a PDF but I have a scan of a 7104 manual dated "First Printing NOV 1978, Revised FEB 1989". In the "MANUAL CHANGE INFORMATION" at the rear of the manual the late

I had the same problem about 6 months ago. I had 4 7A26 plugins that I had picked up a few years ago but didn't have the time to check out and calibrate. I just couldn't believe when I started on the

The 013-0138-01 is the correct adapter you want, as stated in other messages. But as I remember this one came with another label which was C B E that allowed you to rewire this adapter to this configu

I have an Agilent/Keysight 1733C LCR meter. I has measurement frequencies of 100Hz, 120Hz, 1Khz, 10Khz and 100Khz. It also can be set to measure C with either parallel or series R. I of course used pa

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

Gary: I have downloaded it twice and it opens fine for me. I see others have also downloaded it with no problems. Not too sure what is happening for you. Bill

I just uploaded a pdf of the Tektronix 067-0538-00 input normalizer manual. From the "calibration" instructions, Tek says to measure the input capacitance of a 20pfd input with the scope turned on. Th

Chris: I still have the 155-0022-00 in the original package that I ordered from TEK 20 years ago. If you live in the US or Canada I can put it into a padded envelope and send it to you. It sure isn't

I believe that U510 is P/N 155-022 rather than the 156-022 that you have quoted. At any rate did you notice that both the A3 Trigger Selector and A4 Vertical Interface boards, U324 and U214, have the

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
