Re: Removing the Adhesive From Hell
Brad, I feel your pain on the dried masking tape adhesive, just be glad they did not use filament reinforced packing tape as that is 10x worse of a mess to deal with. I have seen where applying a

Re: [TekScopes] Removing the Adhesive From Hell
If the part can withstand the heat, I've found that pouring/soaking in boiling water will help loosen some adhesives. I've used that recently on some residue on metal parts. Goo-Gone is my go-to but

Re: Removing the Adhesive From Hell
I've used 3M surface mark remover: https://www.digikey.com/catalog/en/partgroup/mark-remover-8001/27728 To clean up equipment and it's worked pretty well. You need to wear gloves when you use it

Re: Removing the Adhesive From Hell
I use a variety of methods and solvents. A very good one for masking tape is to tear up a paper towel and fold (2 layers) into a size a little larger than the tape. Saturate it with WD-40 and go away.

Removing the Adhesive From Hell
Hello-- I'm restoring an older piece of equipment that was festooned with tan-colored masking tape. I'm able to scrape away most of the crumbling tape-- but not its adhesive. Applying Goo-Gone works

Re: Replacing missing button cap(s) - HP 339A
We do need to nip this conversation in the bud. While it is tangentially on-topic, it's not likely to be tolerated for long. If I were watching it as a moderator rather than participating in it, I'd

Re: Replacing missing button cap(s) - HP 339A
I didn't come looking for an argument.... only a friendly discussion, and clarification of some words you wrote. Your assumptions about my attitude are probably as unfounded as any assumption I could

HP8330A radiant flux meter service manual anyone?
I found a HP8330A meter plus 8334A detector and they seem to be OK, apart from noisy readings on CAL and measure. Searching the web for a user / service manual has so far been a dead end, apart from

Yeah that's for sure In the service pages of the RF section I hope to find those power figures of the modules, yesterday I was reading some pages about this section and I studied the block diagram,

Amen to that Dave! Just scrapping nice TE stuff because you own it so are entitled to is plain and simple a statement of "I am an asshole". Wilko

Re: 54615B Agilent Scope Amplitude Low When Measuring 120V AC
The probe is generic, but I tried a newer model Agilent probe I believe. As for the coupling, I believe just DC. The other scope is my higher end 54831. I was unaware specialized probes should be used

Re: Replacing missing button cap(s) - HP 339A
Hey Jeff ¨C In the good old days you and I used to get lots of TE together at those GSA sales. Those were fun and we just split the stuff down the middle along with the payment. I bet it was close to

Jeff, there's more to life than money, and things have value other than pure dollars. I get that some people don't process that, but it's a fact. -Dave

Re: Replacing missing button cap(s) - HP 339A
Well as this very much Lib, but very pro-Tech, I'm willing to admit that there are things in life that I care about, like well-engineered test equipment, and it makes me angry when morons destroy it.

Re: Replacing missing button cap(s) - HP 339A
What a fascinatingly stupid discussion. And I will prove it so: Desired, rare, sought after, beloved implies valuable which equals $, money, moolah, cash, cheese or whatever lingo you choose.

Hello Dave, sorry to step into the fray here. You are an old friend, and I know how you meant it, and in principle I agree with you. But, given the current political situation, there are many, many
