I believe the notch filter could be built in any form factor. IIRC it does not use power from the mainframe, so there's no reason it has to be in a TM-style enclosure. Dave Casey

TM500 - Ok, it fits a very large set of modules. Why? Are there modules that do things that can only be done using a particular module? Yes, I could read the specs for dozens and dozens of the

Good thing! :DLOL!? ?Happy New Year, everyone!? ? ?JimSent from my Verizon, Samsung Galaxy smartphone

We had a 1000-foot spool. Thankfully, the label specified that it was a single cable with no breaks. RG-59 I think. I do not recall what the prop delay was, but it was sort of measurable. I recall we

hi Miguel, really interesting, but first I have to recover the 52.5 MHz crystal to convert the TR503 to TR502. Among other things, the TR503 does not have the logic interface (the one connected to the

I have the original power cord for my 513D, and it is a 2 pin round bodied "extension" cord, of a type that was popular in the late 1940's. The instruction manual clearly indicated that you must

Note that Jared has updated the main PWB Gerber file and the Instruction Manual file; if you downloaded those earlier, you need to get the new files. Jared and I are discussing how best to order these

Steve I in 2014 did a paper for SMPTE, Belden contributed 100m reels of cables to the project, both TP and coax of 18 different types. We ran digital audio signals with rate to 24.576 MHz and looked

Of course! After a few drinks and too much to eat, at 1:30 AM while being a one finger typist, with the computer accepting anything I type, viper sounds like wiper anyway! I am glad I did not type

I happen to have the board Layouts for 475 and 475A and after a cursory look, they appear to be almost identical. They are, as someone else noted, completely different from the 465, but they do

No but it will sound fantastic, especially when you use oxygen free Tektronix Gold Plated Probes... Harvey

I think the best compromise might be the 3 pole midget twistlock from Hubbell, as it will give me a grounded connection, and the modification will be the lest conspicuous: slightly enlarging round

When I came across this problem (and after an unsuccessful search for my genuine ancient line cord), I took one of those rubbery 3-prong-to-2 prong adapters and, with a sharp knife, cut off the female

Yes, C1374 is in a good place to explain a lot of what you're seeing. But schematics aren't board layout, and the TekWiki links for 475A don't seem to have the board layouts. So I don't know how

Probably not. Posting for a friend. :-) HAPPY NEW YEAR to everyone Bill

An IEC would definitely need an adaptor plate. The less common type with mounting holes above and below rather than out to the sides might be a better fit. The other type I've used (again this betrays

Thanks Bruce - 'General Electric' extension cords is giving some good hits. I guess these weren't grounded via their AC socket?

no ground on the ones I serviced, I changed all to 3 pin IEC ( they are/were on other non TEK equipment) as it was required for safety...IMO was not needed but ya do as ordered. above my pay grade.

Thanks! An IEC socket /almost/ fits, but would require a little bit of filing, and maybe a plate to fill in the remaining gaps. I'll take a look at the EP - I think I remember seeing them on consoles
