Warm up the vacuum desoldering iron. If they are TI low profile sockets, until you replace all of them, you will have issues. I can remove 43 sockets in less that 30 minutes, if the pins are not crimp

Those sockets loose tension over time. They are very problematic. Cleaning will not restore the tension. Replace ALL edge wipe TI sockets with good quality double wipe sockets and most of your reliabi

Ensure that you remove all traces of the WD40. WD40 is a water displacer. It will leave a gummy mess. Glenn

Regular tin/lead solder will leach the silver out of the ceramic, over time. The silver is added to the alloy to prevent this leaching. IIRC Tektronix used an alloy with 3% silver. The common alloy th

It is not the wattage as much as the voltage. Resistors have a voltage rating. Glenn

I am interested in one. Do they have any numbers on them? Glenn

We got some hand me down Hitachi analog cameras for the NEWS department of the TV station that I was CE for. NEWS just had to have the working cameras in the field NOW. About 50% of the bad cameras ha

So, what does conformal coating do to prevent leakage? Possibly hide the damage? Glenn

Be very careful, you might remove the trace under the capacitor by twisting it off. I worked with a tech? that used this method and he destroyed a few boards. I know of no reputable repair school that

Would there be any data available on a Tektronix built Interad 7121R spectrum analyzer? Thanks Glenn

That is Deane Kidd's stock. Being sold by his family. Deane was very helpful in helping maintain Tektronix equipment. Glenn WB4UIV

I bought a number of 2 GHz amplifiers at a hamfest. I called the customer service number for the company. The person in customer service sent me the checkout info. When that package arrived, I called

Many years ago I bought this from Deane Kidd. It has been in my back room since. The plugin is serial 000096. Serial 000098 sold for $100.00 as a parts unit. The power supply has no type number on it.

What is the failure mode of these relays? If it is contact resistance, they can possibly be recovered by operating the relay with AC on the contacts. This is a common problem in some Harris radios. Gl

What is the Tektronix part number? Glenn

I am currently working on drawing a schematic. Slow going. Hope to have it done and posted sometime in February. Glenn

I use an older PACE desoldering station. It has a filter in the collection tube and another at the junction of the vacuum hose and the pump. The pump is a rotary vane. I have removed about 10 pounds o
