Paul, Devcon makes two metal filled epoxies which would probably not make great potting material because of conductivity. They are outstanding repair materials however. The original one is Devcon A.

many thanks for the IC catalog scan.? excellent! the hp/agilent users group has also moved to this server. you can now find them at: /g/HP-Agilent-Keysight-equipment all the best,

Very valueable, must be a lot of work those hundreds of pages. And al text-searchable. Thanx for both of you, René

Glad to help. More coming.

Ditto. These are great! -- john, KE5FX

Thanks a lot, Pete and Kurt! Raymond

Hi Miguel, What modifications did you make to the charger circuit to adjust it for the different charging requirements (current limits, voltage cutoff point, etc) of Li batteries compared to NiCd

Not in normal use, no. Unfortunately, there's a lot of them where someone just took the probes anyway, they do plug in, but it's internal. Ask me how I found this out... Harvey

Scope probes are not detachable for any 211, 212, 213, or 214 scope. Dennis Tillman W7PF

Hi again Now I have done quite a few measurements with my 7L13. I just used a know frequency source to tune it into the frequency I am searching for and then I do the measurement. This works well

hi, Spotted on eBay: Tek 545 with tubes for parts... $100 located in: Crimora, Virginia,

Indeed and almost too easy to fix! It turned out that the coaxial wire going to the ext Z-axis BNC had come adrift. Re-soldered and now z-modulation is functioning, but still no bright-up on "A INTEN"

Just try a Helicoil first, I just fixed some stripped bakelite knobs from a 1920's radio using 4BA Helicoils - worked great! Adrian

Epoxy resin mixed with enough ground silica to make a stiff paste then rammed into the hole Robin

plastic is fairly soft compared to metal, normal thread is 70%, you can use a smaller tap hole to approach 95% thread, use a good sharp tap. plastic threads will hold better and longer with more

He is wanting to replace stripped inserts in knobs, seems like a great application for easily tap-able jb weld. No concern about viscosity in that application. I'm not sure Micromark's bismuth/tin
