we are going to get slapped for this geezer fest, but now in my late sixties i exhibit all of the above annoyances when typing with one addition. i am basically a touch typist but developed some bad

I’m mid 50’s and I just realized I missed a word on my last post. I meant “when he DIDN’T find it”, but wrote “when he DID find it”... See? It’s not only age, it’s also that

Indeed, but that didn't stop the tek engineers from trying to make FOCUS a universal control that worked equally well on both beams, and the readout. They failed, of course, but got a pretty good

They probably would ship to Paris. But honestly, it’s not financially worth it at all. It works just fine with the 3904’s, and I could put some higher current handling ones like the 2222A if need

If focus stayed constant irrespective of beam intensity, there would have been no need for a front panel focus control. -ls-

We're all aging, one day per day. I swap keystrokes and beat the shift all the time. Five years from now someone will search for "FG504" and if not for pedantry, they would miss your helpful

I remember my disappointment when I started collecting 'scopes in 2012/13: I fed the < 1ns rise time signal from a PG506 into my newly acquired 7904A at a fast time base setting, expecting to clearly

I could type 40 wpm on a manual typewriter all day with very few mistakes. I suppose that dates me. Now I can't type a line without a couple of typos. My theory is that as the cost of a mistake

I am mid sixties as well, but to further my stress is a little dementia thing that runs down my mother's side of the family... I have always edited myself, but lately there is way too (just typed as

Just out of curiosity, Mouser.com in the US does not ship to Paris? I know there is a Mouser.eu, but it should be easy to get around that limitation if need be.

Mid-sixties here and having some of the same issues. I work with a lot of various systems and am constantly crossing up numbers and letters (or conflating one system's numbers with another, etc.).

All in the USA unfortunately, but bit the bullet and bought one. Cheers guys.

It is becoming a touchy subject for me. All my life I have been a very fast touch typist. I spent a lot of time writing programs, and later writing documentation, and could always type quickly and

Your description is pretty accurate. The more modern scopes have compensation circuitry that changes the focus voltage with the instantaneous intensity setting.... and changes the

I make typos all the time. Especially with multi spellcheck in different languages. It writes whatever it wants... If I don’t double check... Don’t worry, it’s okay. I understood you were

No, the typo doesn't matter in so far as that is what it was. I was just curious because I am trying to get a FG504 working correctly and not doing too well at the moment. I didn't mean to insult you

Honestly, does it really matter that I mistyped FG504? I am talking about ceramic trimmers that exist in hundreds of Tektronix instrument models. -Chuck Harris Colin Herbert via groups.io wrote:

Luis, Since both channels are equally affected the fault must be either in the beam switching circuitry (not very likely) or in the Y amplifier stages following the beam switching. There is a fairly

Do you mean an FG504? I can't find any FG540 on TekWiki.
