Re: Transistor Cross Reference

Dave Casey
 

The Tek cross reference shows the 151-0062-00 to be a GA1392. I know that
in some applications, such as the 3B1 and 3B3 plug-ins, a product
modification (050-0581-00) was issued to replace the -0062 with a -0224
(2N3904).

Does anyone know a good cross for the Tektronix transistor N101 (151-062)?




THS730A, 720A Channel 1 issue

On both of these Chan 1 only passes the DC portion of the input. Connecting Chan 1 to the built-in compensation reference I get a 2.5 Vdc trace (which is the DC component of the 5Vpp square wave).
Chan 2 works fine on both. Both pass all self tests and SPC. The probe is good.
Can this be a cal issue? I have the service manual and schematics and plenty of tools/instruments, just wanted any insights before diving in.

just do a search on Amazon's (US only) site for TM500x -  comes up as second item, gets beat by a TM500XL TomTom battery!

I've offered these in the past. I made them for my own use, and for forum members. Since then I have become an Amazon seller so I've added the new updated version of the extenders there (see link below). I'm selling the fully built set for $45. For group members, I will sell the bare PC boards, or the PC boards with the SMT components on them, if anyone wants it in kit form. Email me off list if you're interested in the "kit" option.
If you get just the PC boards, you will need the 60 pin sockets, ribbon cable (w/ connectors), board pullers (optional), and the 56-pin edge connector (and optional polarizing key between pins 6 and 7).
I could even put together a complete kit for fellow Tek-heads, again just email me off-list and we'll figure it out.
I am not trying to make a profit, just giving back to the group. The Amazon fully-built set takes a bit of time to build (about 200 solder connections) which is why I'm asking $45 for it.

Re: Tekwiki

 

THANK YOU KURT FOR CREATING MY FAVORITE TEK SITE, TEKWIKI.

It is a complement to you that TEKWIKI is every bit as good as Wikipedia.

I, for one, am amazed at the quality and professionalism of TekWiki.
We are ALL extremely fortunate to have the incredible TekWiki site to support us.

This is clearly a labor of love. Where do you find the time to do it all????

Re: Looking for 475 Handle Cover (200-0602-00)

Norm - KC1BMD
 

Anyone looking for a replacement hinge cover for 465/475 series scopes, try this:

https://www.n0dy.com/product/tektronix-hinge-caps/
https://www.ebay.com/itm/Tektronix-465-465B-475-475A-Replacement-Hinge-Caps-Set-of-2/152850739291

The caps are black (not Tek blue) but they fit perfectly and are easy to install. They make my scope look so much better not having to look at the ugly hinge that's missing a cover. The seller is a really nice guy who sells used 465/475 series scopes that he fully repairs and calibrates before the sale. I'll keep an eye out for another original blue hinge cover but they are so rare. The black hinge covers are a great compromise on aesthetics.


Re: Tek 2465b with down shifted display..

 

It is my standard policy to replace all SMD capacitors with regular leaded (legged) capacitors, soldered onto the SMD pads.
It is a reliability issue, the cosmetics are completely irrelevant.

On most 1990's equipment (which have the troublesome SMD caps), there is almost always sufficient vertical clearance to stand up the new caps in the vertical position.

On newer equipment, such as the LED-type TV's, which have become a major part of my business, there is usually not sufficient vertical clearance, so I mount the newly-installed regular-legged caps horizontally.

And as is to be unfortunately expected, with all the junk components coming out of China, on the new TV's, I am now seeing SMD capacitor failure after a year (not after 20+ years, as on the Tek 24x5 scopes).

It turned out that nothing is wrong with it. The SG505 requires a 600 ohm load on the output for the dB scale to be accurate. Without the load the voltage will be double what it should be (into a high impedance load of my other Tek meters and scope. Zero dB into 600 ohms is V = Sqrt(P*R) which comes out to be Sqrt(0.001*600) = 0.7746 volts.

I don't have 600 ohm terminator or pas-thru so I tapped a line off into an old Decabox. Now the RMS and Sync voltage calibrate perfectly. I'm going to try and swap resistors in an old 50 ohms terminator. Last time I did this I melted the BNC's internal nylon insulator. Maybe I should install the BNC to another BNC to help heat sync it while desoldering it. Surely there's a trick of the trade to desolder a terminator.
