Well, I'm an old fart but definitely interested. Thanks, Don Black.

Well, the link looks like it should now work, pity it doesn't. You need to cut and past the last bit after "Hon" onto the URL when the first part comes up. http://www.labcompare.com/617-News/844-Unive

That's nice he's being recognized for his life's work. I guess that developments since the 7104 days must have improved the reliability and long life without deterioration for space work, you can't ju

Thanks for the excellent description of their construction and manufacture. I guess the electrons entering each pore initiated secondary emission? Were the tubes lined with a conductor or the glass ch

Thanks David. Don Black.

Is there a concept book that describes the micro-channel tube and how it works? Don Black.

If someone has the German version the illustrations could be added to the English translation. Don Black.

I just tried getting the shipping cost for 10 covers in the US and it still came up as #10.95 (same as for one). Don Black.

Well, I'd like to buy some but the shipping to me in Australia is $45.50. If any of you in the US are buying some and would be willing to buy 6 more, post it to me for the actual cost, I'd be happy to

They're planned for release next year at exactly the same time. Don Black.

They have a big special on freeze spray for just one day each year on April 1st. Only 50 cents a can or five for a dollar but only in the extra large size. Don Black.

Never saw the woman but she did a good job. Don Black.

I love it. Pinch and a punch - first of the month. ;-) Don Black.

I have a friend who does exactly that. Last computer lost sound, now has a new one. My Mum is like that too. Her fairly new clothes dryer is noisy, I'm going to look at it for her. She just wants to c

I have a laptop here that I was given. A woman got so frustrated (mad!) at it she stomped on the screen with her stiletto heel. Not pretty. Don Black.

Hello, I've just got an S12 TDR, S1 and S6 plugins. However I don't have a pulser. I eventually hope to find a S52 that I can afford (or save up for) but meanwhile I'd like to try making a simple puls

I think I've heard of a French scope (CSF?) that went to several GHz but don't know the details or how the transient response was. Anyone have any details? Don Black.

Very good. I believe the 519 was about 10 volts per division, the actual value for the particular scope (tube) marked on the front. Don Black.

What's the current lore on using Deoxit on Tektronix switches. It used to be warned to only use isopropyl Alcohol. Deoxit has a very good reputation, is it OK for this scope? Don Black.

Thanks David, a valuable reference, those three "spare" transistors are very handy. I also had a look at the LM10 OP-Amp/Regulator IC which was mentioned via one of the forums recently. I guess it's o
