Hi all, I'd be willing to undertake the 3D modelling and printing with a durable nylon material if I could get my hands on a reasonable existing foot to take measurements from. I've already developed

Hi TekScopes, Just a quick note to let the group know that I've developed a replacement hinge cover for Tektronix 465 (S/N > 250000), 465B, 475, and 475A oscilloscopes. This is the plastic piece that

Just wanted to let the group know that I've developed a set of replacement feet for Tektronix 453A, 454, and 454A scopes. These feet replace both the plastic piece and the metal post/insert. They're m

I'm guessing it means a fairly long period of time... ________________________________ Sent: Sunday, December 24, 2017 4:23 PM To: TekScopes@groups.io Subject: Re: [TekScopes] ArtekManual Danaher 577

Hi David, Thanks for the info. Taking a look at the datasheet, yes, what I have are definitely the Minisert sockets. In my case, the rear of the board is not accessible without a complete teardown of

Hi all, I have what I believe to be a bad transistor socket in a 475 I'm repairing. I think the socket is bad because every time the scope acts up, I can fix it by wiggling the transistor in the socke

I have a copy of the2X45B/2467B Option 10 Instrument Interfacing Guide (the GPIB Option Manual David refers to). Some of the commands to obtain measured values are: (NOTE: Valid only for the B scope v

From the department of "How Stupid Am I?". Last night, when troubleshooting a DM44 showing random, nonsense digits, pretty much regardless of the measurement setting, I started looking at signals with

Not sure what exactly you have two of... 😊 I've posted some test results from two samples of the build I did following the notes from Sergey Kubushyn. The test was conducted over the noon hour on an 8

The Tunnel Diode Pulser is relatively easy to fabricate, if you can find the tunnel diode. I built a couple myself from the description here<https://groups.yahoo.com/neo/groups/TekScopes/conversations

Hi Walter, Sorry I didn't reply earlier. I am interested the the 500 series plugins. Thanks for doing this for the family. Looks like a ton of work. Best regards, Jeff ________________________________

Hi Joe, Well, I was actually talking about the 475, but after looking I see that it's also true of the 465 manuals. I've done one or two replacements on them as well. One gotcha - removing the screws

Hi Mark, I've removed and/or replaced the 475 HV multiplier about 3 times. In each case, I just followed the directions in the Service Manual for High Voltage Multiplier removal carefully and had no p

Check the junction of C1038 and R1038. C1038 is a 15uF tantalum cap, and if shorted, will pull the supply down. I'm sure there are many other possibilities, this is just the result of recent experienc

I learn so much from following this group!

Mark, I've had this happen to me twice before (on two different scopes) - the scope working fine one minute, then all display dead, no beam finder - but fan, indicator lights, etc. OK. In both cases,

Hi Mark, I've been looking for the parts you mention (Q1416, F1419, R1412, etc.) but can't find them in my copies of the 465B Service Manual. I have both the before and after S/N B060000 versions. Can

Larry, I have a TM506 power module taking up space. Since you live not too far away (I'm in Ladera Ranch), it's yours for picking up if you want it. Contact me off list if you're interested. If you ju

I use my homebrew pulser (built to the same schematic as the Tek device) with a PG506A, no problem, using the high amplitude output. Jeff / N0DY ________________________________ Sent: Wednesday, Octob
