I could have sworn that the last time I visited the Tektronix site, they were still offering parts for many of their older probe lines like the 6105 series. Thanks for the tip. I will bookmark them.

Isn't benzene a key component in gasoline? It was one of the first carcinogens mentioned on California's Prop 65 list. It's why gloves are supposed to be available when pumping gas. I understood it is

Toluene huh? I was wondering why I liked removing old calibration stickers so much ;-)

Back in the old days, when we were much more devious, we used to soak rags in MEK and throw them under the bosses door - usually in an hour or so he would go home with a headache. In the Navy we used

Acetone is also a very efficient flux remover and leaves very little residue. I also use ethyl alcohol. It is a little harder on the skin. I "Goo Gone" for removing calibration sticker residue and it

I prefer the old rosin flux cored solder myself and I've been told it's pretty inert when dry so it can just be left (although it ain't pretty). That organic stuff is pretty caustic. Definitely worth

I was always curious about that myself, having received training at numerous military industrial companies in the '60's, including a 2 week stint in a NASA soldering school in my early days as a journ

For instance a Hammond B3 organ which costs $3000.00 in 1964 would cost $16,962.96 today (2002 is the limit of the calculations)

Try this. http://www.westegg.com/inflation/ Enter the original year and cost and then the current year and it will calculate the current costs. I am sure that the original costs took into consideratio

Actually I just tried it- made the filter look like brand new. I have cleaned it the hot water and soap method for the previous 15 years. You're right about the aluminum pitting - I never machine wash

Range hood filters are very similar and I clean mine in the dishwasher and it does a spectacular job. Although with all the grease in a range hood filter you wouldn't need to "tackify" it. Also I am c

I have foam filters available for 400 series scopes for 2 bucks including postage & handling

I think he needs to buy one of the tubeless scopes on eBay (there are now three) and retube it!

I am having a couple of problems with a 434. Both traces shift vertically 5 divisions while the inputs are grounded with the channel ground switches and the internal calibration square wave will shift

You mean you're not going to give us the answers!?!?

I have actually bought a fair amount of gear from gov. liquidators. Most people (like myself) wait until the last minute to bid (so the $35.00 minimum bid price will change -sometimes dramatically). D

"I was wondering if anyone in the group did get unsolicited offers for dirt cheap software" Isn't the general rule that if it seems like too good of a deal it probably isn't?! Sounds like a scam to me

Thanks Craig, Very interesting site. It made me appreciate my V5 Variac (in almost daily use for over 30 years) and decade resistor box even more. "Subject: [TekScopes] GR, not Tek!"

I have found the same thing. I always verify the value of caps and resistors in my spare parts box before using them. I've been starting to notice a problem with most carbon resistors in general that

I believe that NBS (National Bureau of Standards) is now NIST (National Institute of Standards) and I doubt that the mil standards have changed much. I have audited metrology labs and have actually ca
