Hi,I'm having trouble lifting heavy things now (surgery on both rotator cuffs), and the son will soon complete his Computer Engineering degree, move away, and then I'll try to move these and be

I don't know about the screen flickering, but I do think the YTO loop behavior is normal. At wider spans it is not constantly phase-locked - it is driven open-loop with fairly accurate sweep current,

Hi Tobias, Great job and a great write-up to go with it, thanks for sharing your work. Your story reminded me of something I learned from my first ever boss after I left school (over 50 years ago now

Hi, I'm not sure there is an exact match in the RAL pallet. The nearest I have found for instruments of that vintage is RAL7042. That looks ok for panels that I wanted to 'tone in' with the HP

Hi guys. Over the years I have read a lot about yigs going bad specifically their coils seem to go bad. Is there anything that can be done pre-emptively to secure their longevity? And what exactly

I am not familiar with that model (I have a 1727A) but if it is anything close to the Tektronix 465, there are attenuator switches operated from the panel control that may be making poor contact. I

Can some please share with me the paint code used by HP for front panels in the 60’s? I have a very early 410C I’m trying to redo. The color is more dark than the RAL7044 used on the later 410C

Hi Ed many thanks! Yes, I was really lucky with my YTO. However, I am a bit afraid that the YTO could definitely fail some day and I would like to have a spare, but there's none :-( I even thought

Hi all I have a 8568B spectrum analyzer which has some strange flickering traces sometimes. I found out that the traces do not flicker if the frequency span is narrow, for instance 1 MHz. As soon as

I too expected that electronics professionals and hobbyists would be above that sort of nonsense and would refrain not only from indulging in conspiracy theories and political rants, but also from

Dan, I certainly agree that this is not the forum in any sense for a political debate.? Unfortunately you went on to engage in exactly that.? "The Media" has destroyed its own worthiness and

Wow. Nice work, Tobias. Sometimes we learn the most when things seem hopeless. Your reasoning was right that there was nothing to lose by taking a chance on opening the YTO, and you came up with a

Greetings, I have been reading some of the posts regrading the inaccurate reporting regarding the Keysight plant in Santa Rosa. While I find inaccurate reporting as disturbing as most of us, I must

Hi all, probably some of you have seen that I had some problems with a 8341A. It was indeed the YTO which failed! But, I was incredibly lucky to fix the YTO. I also did a front panel RF output

The signal is being differentiated, as if it is being coupled through a small value capacitor. I would first look at the attenuator switch contacts on those particular v/div settings for an open or

Hi all, I've been a member for a while but lurking in the background while working on the scope and looking out for any discussions about a 1740A taking place. I now have the scope in a running

The probe is spoken for - thanks... geo

I have family?living in Sonoma as well and don't really appreciate the directing this conversation has taken, As a retired LEO I have a real issue with people who attack the guardians of our first

Please please keep politics and conspiracy theory rhetoric away from this group. If I want rants and abusive postings, I can find gobs of them on sci.electronics.design, surrounding a few technical
