sean, I have 4 of the tek 152-0071-00 diodes, I can send them to you in a padded envelope if they will help restore your 1S1 to life. just email me off-list. they look like ordinary glass diodes, but

These just keep turning up in places I didn't expect, so they are now added to the stuff day page here: https://www.sphere.bc.ca/test/stuffday.html#tekfans I was also able to identify 465B and 2205 kn

Few things are as frustrating as when the vertical knob on a Tek scope is damaged, by cleaning (hah, you didn't know the printing washed right off, did you?) or mechanical wear or other damage. Many d

I just can't seem to get rid of things, a local ex-service center guy just dropped off a big pile of gear with me, so I am offering it free to anybody interested. There's Heathkit, Sencore, RCA and B+

I just want to mention again that all the issues raised with regard to module extenders are important, and no matter which route you go, the result is always a bit sub-optimal, and awkward on the benc

I noticed we had a bunch of these new military HV multiplier assemblies, They may prove useful for fixing one that has tanked in your scope. the part number is SCMA 10139, and they are at the end of t

Barry, the /123 means it has a graticule in the CRT part number. These are all for Philips scopes. regards, walter.

The post-demise sale of guys with lots of gear is always a bit sobering. Part of the reason Suzie and I are running the Stuff Season event is to help move useful bits out to anybody that can use them,

As luck would have it, I bought 2 new 155-0001-00 hybrids in a big parts buy 2 years ago of Tek service center components. I often wondered what the heck they were... I have 2 new ones still in anti-s

These plug ins are a perfect example of the common 3rd party front panel TM500 design, note they are a simple flat aluminum plate, screwed to the top/bottom rails. a white overlay obscures the screws

The two custom plug ins I use regularly are my 10MHz standard and my TM500 frame tester. They both are useful to me and fill a need I couldn't easily fill with a Tek unit. I(( can send pics if you wan

Just a brief comment on TM500 module faceplates, especially as it relates to test plug ins. 1. the layered plastic/metal front panel is not really useful for most locally made items. Its purpose for T

Following this thread, I remembered that I had some odd BNC terminators in my accessory drawer. I just fished them out, and they are ELCOM FT-90, BNC (m-f) terminators and measure between 91.2 and 93

A few comments on the ebay extender (which I have nothing to do with personally). 1. the edge fingers *ARE* chamfered, it is clearly shown in the pic, and it even says so in the text. I found all the

For greater clarity, the problem that arises with unapproved gear is one occurring *NOW*, not back in the 90's. school/university insurance is not currently permitting use of unapproved gear, and that

I have noticed that much of the Tek gear we all seem interested in has no electrical safety approval of any kind. the same is true for HP gear. at what point did Tek actually incorporate equipment saf

the 3WP1 was also flat faced, and extremely sensitive vertically, which should have made it very popular, but it is quite long, and failed to really get a big following. although it was used by Tek in

Little CRTs around the world: There are several 1" CRTs that have been around for a long time, the 1EP1 is the nicest, and easiest to use in circuit. that was an RCA design, flat faced and sensitive,

*Yet more tiny scopes were made by Vu-Data*. I have had several of these "PS Portable Scopes", but none left at the moment. There was a low frequency unit, PS900 (1Mhz?) and the 35MHz PS935, with its

As I understand it, the ONLY reason for the existence of the delay lines in the vertical amps was to allow the trigger to be captured early, before the waveform, allowing the display of the trace lead
