Hi Robbie, The Tek solder is flux cored so all you have to do is follow the soldering instructions in the manual. It's not a bad idea to install connectors in the motor leads. Purists might object

Hello Mickey, Try unplugging the ribbon cable that goes to the CRT assembly and re-try powering it on. Jay

Domestic water softeners, yes. However laboratory systems for deionising water still use ion exchange resins but these are designed swap all cations for H+ and all anions for OH- so the result is

I agree that you don't want the residue from hard water left on anything, but in reality, most of the rinse water will (should) be removed by air-blasting. There can be some left for evaporation, but

Would a dual channel plug-in set to differential mode do the job?

Where are you located? FYI SF bay area: http://sfbay.craigslist.org/sby/ele/3131223928.html If you want this one, maybe someone could get it for you. Bob

Tek used to have slip-on plastic covers to slip over the cardboard electrolytics. Probably hard to find now. But, you could use condoms !!? Lubricated variety not necessary :<) They also had

Sorry, I don't buy it. Poly silicone oil/grease is NOT soluble in water. It is possible that a microscopic amount could be dispersed in suspension, but without an intentional process to emulsify

Thanks for all the replies. Haven't found anything locally on craigslist but I'll put a want in on the West Coast 40 Meter swap net and see what I can come up with. I'm watching a couple on

Dave is correct on that as well. Forgot about those.

It is a bit more complicated than just the ions and what is left after evaporation/boiling on soft water vs. hard, etc. I don't want to get to technical nor argumentative. However soft water via ion

Beware of medical grade distilled water, it contains silicon greese, which is used to lubricate ground glass joints of distillation apparatus. Better choice is '10 Meg' de-i water, standard water for

They are different double resin ion exchange systems as use to produce "deionised" water. They swap H+ for the cations, and OH- for the anions. Dave

Thanks Albert. I was reading the maintenance troubleshooting chart which says that if there is no trace or dot when you press BeamFinder: "Check sawtooth at both horizontal deflection plates (about

Ah, so... ion exchange (water softener system) does imply conductive/salty as I was thinking.

I am looking for a good Tek 422 CRT, P/N 154-0466-05, at a reasonable price. Will consider buying a parts unit. Please PM me with details. Curly

Bill, I'm wondering if that's noise from the D-to-A converter circuit, maybe because a low-pass filter cap is open. I'd suggest to check on the Storage Display Logic Board (A16), which is the

That is because there is so little in a small drop that you most likely can't see it. If you put some quantity in a clean beaker and boil off the water, what is left is a concentrate of what is in the

Sodium carbonate is much more soluble in water than calcium carbonate. It also does not react with the soap to make soap scum. Softened water was an improvement for washing PC boards but we still

Hi Keith, This is fine for a normal sweep. The flats show the hold-off time after retrace (or waiting time until next trigger). You should look at the *differential* signal, which is 80 Vpp or
