I am in the market for a 556 in decent condition. They are just so damn good looking!!! Anyone out here looking for a good (permanent) home for your stagnant 556?

One more to add to the heap if it hasn't been mentioned already. I watched as one of our top rework operators removed "chip" resistors, caps, inductors. She would use two irons of equal tips, heat

I was recently given a bunch of components from a 549 scope. What a beautiful piece of engineering. I was inspired to create something to help the bits live on. I built a 1 tube regenerative receiver

I just happened to think Now that I no longer have 5 extra bodies around here, I don't really need to keep their tools either I do have an extra Ungar / Weller 4624 Solder / de-solder station I could

Hi, I remember hearing of a company that used long thorns from a local bush to clear solder-filled PCB holes while heating the pad. They don't wet or conduct much heat away but are unforgiving if you

35eur special offer for one 7B53A or 7A18, "as is". Maybe not a great offer, but OK for europe i would say. <http://www.surplusasnew.de/fix/she.html> I have nothing to do with them, just saw the

I have acquired a 2235 Option 01 oscilloscope that displays the following symptoms.... 1) The "A" intensity control changes the intensity of both "A" & "B" traces...the "B" intensity control does

Yes, that's what I just did with a board from a Dyna dm2400 cnc m/c. The L295 solenoid driver ( used as a stepper driver) had gone down with a few diodes gone with it. Not having sophisticated

The best tool i have found is this one: <http://www.howardelectronics.com/den-on/sc7000.html> I would not want to work without it any more. When we got it, the first thing we tried it on was the rear

A fellow from plant engineering at an auto plant told me how they repaired boards at the plant, where down time is really expensive. They cut the ic from the leads, remove the leads one at a time and

OK I have done some further testing and found the following: With the output of U1311 (pin 6) disconnected and the inverting input at -13V and the non-inverting input at -4.5V the out still remains at

Greetings, ? I bought a Madell 850B SMD Rework Station last year. I do not use it as much as I thought I would but it is great to have around. I use it to preheat ground planes that my small irons

From Tim P (UK) further to the discussion on removing components from boards, I remember Weller produced a device for de-soldering ICs which was like a metal IC socket on a soldering iron, which went

So I'm not the only one makes weird soldering tips. I had to make a .5" wide one a while back that worked great. I also made one with a 2.5" wide blade for a DC/DC converter that was really stubborn-

Why not get six standard alkaline AA cells and run it as it was intended ? /H?kan

Hi, I am very close to replacing my 475 scope with another 465. Having a little trouble deciding between replacing my 475 with another 475 or a 475A or 485. Just doing a little more checking. What are

I have 1 CG551AP which is having issues with its Low SAC that I can't seem to understand. The output of the Low SAC is being driven to -12.5V, after some stuffing around I have found that the output

Re: [TekScopes2] Re:Replacing caps Hi everybody Hurrah, I just got my TDS 544A working, usual acq fault, replaced all the electrolytics on the acquisition PCB - still same fault, so I replaced all the

Hi everybody Hurrah, I just got my TDS 544A working, usual acq fault, replaced all the electrolytics on the acquisition PCB - still same fault, so I replaced all the double and quad SOIC op.amps (TL

Just acquired a TDS460A. Display intensity seems low (I have is set to 100)?and the contrast adjustment does nothing (on both internal and external monitor). Is this a common problem? ? Is there an
