.....snip Sorry to barge in so late in this thread, and have not even read it all the way to the end, but it reminded me when back in 2004 got my first Tek scope, a 2213A with the typical

Re: 7834 Missing Trace

Unfortunately the problem is just that. I can get a trigger light on both of the horizontals, with the display set to either CH1/CH2 or chop, but there is still no trace. With the side panels off I

Re: Preventing SPAM from new members

The occasional spam doesn't bother me, so I'd encourage Dennis (et al?) to choose whatever mechanism is least work for themselves. It isn't just mask guys; electronic components as well :( I've

Re: Why would you do this?

Paul, Me Too! A "needs repair" 465 with no trace, busted up knobs and that looks like it came out of a dumpster; priced at $200 + $100 shipping is too rich for me. Viable Alternates anyone? --

Re: FG502

The fine adjustment knob gives about a factor of ten improvement in the precision with which you can set the frequency measured against a DC503 counter. The only reason that comes immediately to mind

Re: Why would you do this?

There is a "test equipment for sale" group. Certainly more limited than Ebay in audience, but you are likely to get people who are more interested in the equipment rather than tube

Re: AWG2005 Issues and Repair Question.

Stephen, Yes, I have a 2440 and that is one of the scopes that must be constantly cooled to prevent overheating of the A/D Converters and the CCD Hybrids. I think that Martin makes a good point,

Re: Why would you do this?

What are the alternatives? Ebay was great in the early days; I got a ton of useful equipment. Not so great these days and I'd love to go somewhere else. Paul -- Paul Amaranth, GCIH

Re: Why would you do this?

When or If this happens to me, I will also be out. I am only a "small potatoes" seller, but I will not submit my information to a foreign bank, just to stay on E-Bay. PayPal is its own boatload of

Re: AWG2005 Issues and Repair Question.

Stephen 3:40am #170085 I’ve read somewhere, maybe TekWiki, that when working on these digital/analog “hybrid” scopes, you could fry a chip within a few minutes if it’s open and not properly

Re: AWG2005 Issues and Repair Question.

Martin, One thing that I am certain of, that fan is working. It sounds like a jet engine next to my 465B. That being said, overheating or issues with the ECL chips could still be a problem. The

Re: Why would you do this?

In case anyone is unaware, eBay has now cut Paypal out and is forcing it's members to give their financial info to a foreign company or the accounts will be closed.They are ramping that up in groups

Re: AWG2005 Issues and Repair Question.

I worked on a awg2021 and I'll bet your problem is overheating. The 2000 series uses ECL logic and those chips get extremely hot! With the cover off be sure to always place a good powerful fan

Re: Message to satbeginner and Saroj Pradhan re: Tektronix 2230

I personally would love to know how, and wind transformers too. Very interesting stuff indeed.

Re: Message to satbeginner and Saroj Pradhan re: Tektronix 2230

..and I was interested in their experience winding the transformer. I would never have the patience for that myself! Dave

Re: Preventing SPAM from new members

These mask guys have been doing this on other groups. Dennis is 100% correct in his new policy. They ask some question, usually a how-to, and get approved. Then after they're approved here it

AWG2005 Issues and Repair Question.

I recently obtained a SONY/TEKTRONIX AWG2005. It had a couple of issues. First the power supply would quit working after it warmed up for about 30 minutes and would not restart until it cooled

Re: Triggering problem with TDS6604

Hi Jim, I found the cause of the trigger problem with my TDS6604. It was the trigger chip - luckily we have an SMD repair station at my work -> they are not too hard to replace if you have hot

Re: Preventing SPAM from new members

There is a TekScopes2 already and they are more agreeable to having off topic conversations. I for one would appreciate it if you took this over there Log into Groups.IO and search on TEKSCOPES
