You might want to see if the unblanking pulses are doing what they're supposed to.? (or blanking pulses).? In some older scopes, there are diodes that have gone bad.? Do be careful, since they may

Interesting that you mention intensity. The intensity adjustment does nothing. I am troubleshooting that now. Barry

blanking problems.? You might want to check the CRT bias adjustments and similar voltages.? Turning down the intensity should make it vanish.? If not, then definitely blanking problems. Harvey

I posted a phot of my new problem. Someone with more experience than I will probably know! Please have a look. /g/TekScopes/album?id=293496 Thank You!

I solved the issue... Digged out my oldest Apple laptop, a 3400c, from about the same era than the AM700 and still working with MacOS 8. Once I formatted a floppy in that laptop the AM700 was

Is the 456 a typo in the table of contents? I think the issue you'll have is someone else recently done a very similar book and gave it away for free.

Silver solder is still made and some RoHS lead free may qualify. See AIM We designed the 500 kHz Metcal SP-200 solder station in 1990, constant current resonant supply. 20 sec warmup time,

I've thought about emulating the MC68681 for a 'proper' console debug card, but didn't need it bad enough. Not sure if it would be possible to meet timing requirements with a microcontroller, but it

Thanks to everybody! @Grayson: they are preparing a better sample pdf and yes, they ship everywhere. Congratulation for your book! Such more scientific than I am. It will be of great hep to me in the

3% appears to be optimum. Here is a table of soft silver alloys: Sn/Pb/Ag Solid - Liquid(C) 60/36/4 179-246 61.5/35.5/3 179-227 62/36/2 179-189 62.5/36.1/1.4 179

I have a spare one I can sell you, shipped from Japan. It's small so shipping shouldn't be too bad as it can be sent as a 'small packet'. Jared

Excerpt from the Tek Type Z plug-in manual: "Soldering Precautions In the production of Tektronix instruments, a special silver-bearing solder is used to establish a bond to the ceramic terminal

Hi Albert, I can certainly try that. I'm almost to the point of just living with this. I've had the boards off and back on all too many times for this little bit of annoyance but I would still love

I've been through checking most of that but there is certainly the possibility of something I haven't checked. I get proper waveforms for the timer chip (U33433). I could always try swapping U3480

This mold happens on plastic knobs also. I take a heat gun to the knobs and the mold just disappears.

Gianni, Congratulations! The book looks nice. Let us know when it is available in the states. I see it is 70 euro and sold out. I would FAR rather have a physical book than a PDF. I would be one of

If no one else wants it, I will take it. Just tell me the shipping fee. Gary Robert Bosworth Cellphone: 626-803-8336 E-mail: grbosworth@... Get Outlook for

Free: Tektronix Scope evaluation board. 9V battery was stored but leaked anyways. Board will have to be cleaned up. Original beat up cardboard box. Never used. Sorry no model number visible on the

Another trick you can pull is to take the second scope, put it in XY mode, and look at the outputs of the character generator, I'd initially suggest the connectors to the V and H boards.? Should get
