These are the tools that were in common use when that scope was built. You might find them cheaper somewhere else, but they are worth the asking price. I've had mine for about 30 years.

Re: 485 power supply switching transistors Q1834 and Q1844
John
The MJ13015 ( Looks like a? Motorola part #) crosses to NTE2319
DUX48A crosses to a NTE386, the data sheets are very similar.
Both of the NTE parts have data sheets on the NTE web site, and show inventory and several distributors
go here:?
Then enter your OEM part number? in the upper left hand corner in the "cross reference" search box to see the data sheets. Both parts are TO3 / 175W / 800V Vce /15A
While I have not used these particular parts I have had good luck on many occasions using NTE crossed parts. . Both of the NTE parts are also available on Evil-Bay and that retailer named after a river in South America. Sphere is always a good bet and very trustworthy, No affiliation to any of the above...? just satisfied customer

They are 151-0368-00. Apparently oem were MJ13015 long obsolete. Though Sphere currently shows 2 new 2 used. I do not find a datasheet for MJ13015. Old threads mention a couple parts but the only thing that seemed 100% to work was BUX48A but it also is obsolete or at least I can't find it. The datasheet I find for BUX48A looks as if it was overkill for the application which might push any failure farther into the box.??

Re: tek part number Prefixes
I have the 1984 materials catalog which has alphabetical and numerical lists.? 119-0000-00 comprises misc electrical components (delay lines, filter chopper, oscillator, power supply, fan, etc.).? Another list I saw included flexible media.? I thought I uploaded those lists to the files area - if not I will in the next day or so.

Re: Typefaces in Tektronix manuals, was Re: [TekScopes] Protecting button labels
I created an album called "Manual spines typeface".
I tried with a scanner but of course, the spines are round... and brittle. They'd probably crack if I tried to flatten them.

Re: Duplicate Messages and messages without previous context
For those that are receiving duplicate messages. Is your email client putting the TekScopes messages in its own folder? If so, your client may be saving your sent message to that same folder. Someone on another list I'm on just encountered that and tracked it down to his own email client. Maybe that's what others are experiencing...

Re: I would like some input on a good wire forming tool.
Yes David. I saw the work Michael Damkier did to his 453 and it was absolutely beautiful. Made me realize some things. #1 slow down and make it as pretty as you can. I have been doing much better with taking my time and making sure things are as right (looking) as I can make them. My pride level goes up a notch when I finish a job and the end result is not just working but also pretty to look at.

Does anyone know what category has the 119 prefix assigned to it as in part
number 119-4701-05
And that raises the more general question Is there a complete list of part
number prefixes and the category they are assigned to available somewhere?
Examples:
067-xxxx-yy are test fixtures and/or calibration fixtures
151-xxxx-yy are transistors
152-xxxx-yy are diodes
156-xxxx-yy are integrated circuits
160-xxxx-yy are programmed ICs
151-xxxx-yy are semiconductors
378-xxxx-yy are lamps

Re: I would like some input on a good wire forming tool.
If you are looking at doing bus-bar work, such as in some 1920's radios, firms that supply tools for the wire jewelry hobby/trade might be a good place to look. My wife was making some things out of silver wire and I noticed she was using several pair of specialized pliers, one with round pin tips for forming loops, that might have bus-bar forming applications.

Oh dear. I am so sorry to hear that. I have left a message of condolence on the site. Although I have
never met Stan and Pat, they being 8000 miles away, I feel though I knew them from the many
correspondences with Stan.
