James, You should know to fan cool the CCD IC on the bottom when out of the case. These run hot. Use a good compound to help with heat transfer from the IC to the heatsink, like MX-4 compound. This

I picked up a 492 recently, shown with a trace in the listing photos, so figured it would be at least partially working. Unfortunately, when it arrived the CRT was broken (thanks to not-so-great

One other thing which might be related is that the chassis (and therefore GND points) are at 65v DC in relation to the mains Earth potential. Here in Brazil there is not really an Earth system used,

Hi everyone. Hoping that someone might have encountered this before. So after the 492 repair, I picked up a nice, clean 2430A which was dead. Including the Rifas, the power supply board had 10

Yup, I wanted to check out my 2465 X-Y mode operation before I bought one, and now it's too late. :( Anyway, I verified that it should work with the 2465 - IF you enable X-Y mode properly. And that

25 Sold, now out of stock one day later. Looks like it has more features than the one I bought some years ago. Tom

HI and thanks for all the links and great advice. I will archive the information as when I went to look at the instrument is was seriously corroded by the leaky capacitors and I decided it was not for

Tim’s original post is from 13 years ago, back on the Yahoo group list. I wonder if he is even still subscribed to the new groups.io list. I found several sellers of reproduction feet on eBay. I

I, too, am interested in buying a set for my 465. Arne

Hi Tim, so how much are you looking for a set? Thanks James

Hi, I'm in Toronto Canada but would probably pay a reasonable price plus shipping from anywhere, if someone has a spare or parted out intact plastic bezel for a Tektronix 606 XY. One of mine took a

Ooh nice, been waiting a long time. Too bad ebay are charging 3000yen shipping to Japan for a 5000yen item... I'll have to keep dreaming... Jared

=== Mike, In that case it is normal and expected. When trigger mode is "Auto Level" with no input signal trigger range is set to peak to peak amplitude of input noise and triggers randomly. Ozan

Ozan: The green indicator flicker I mention is very subtle. This flicker seems to go away when trigger mode is set to "auto", regardless of position of trigger level control and with no signal input.

Just thinking out loud: Create a SW app that processes a design file (i.e. Autocad, maybe a monochrome BMP ??) into a format that is fed to the ATMega (via a UART port, or USB). Then anyone could

Thanks George, I'll make a note of that. - Mike, de W9MAS (USA)

Demo boards that display the Tektronix logo and other images on your analog scopes in XY mode are once again available from the museum! https://www.ebay.com/itm/116498624308 -Thomas

If trigger mode is in "Auto Level" does moving the tigger mode to "Auto" and changing trigger level away from zero stop flickering? Ozan

Hi With reference to the display fading only. You are probably seeing a little understood / acknowledged problem with the high value resistors around the CRT. They normally go high in value with

Thanks for the reply. The "flicker" seems to go away with readouts turned off (clear display button). Oddly, the flicker I'm seeing on the green button indicators goes away with signal input (using
