Hi folks Is the 7603 supposed to light up the buttons on the plug-ins? Some of my plug ins definitely have lights installed in the push switch assemblies, but no light emerges. Thanks Craig

Don't feel bad about that one Craig. $132 for a pair of 12AU6 - matched Tektronix or not - is foolishness. That's got to be the audio guys again. Phil

Craig, You can call that 'e-bay syndrome'. I have seen 7000 series plug ins reaching $150 while there were similar ones with $10 opening bids without bidders. Regards Miroslav Pokorni

I'm astonished! I was bidding on a NOS pair of Tek 12AU6 tubes on eBay - a matched pair. Nice for my Type L plug in (didn't really need them, but good insurance). I thought that given the price of NOS

I believe that those digitizers were used to measure all sorts of parameters during test, so a number of them was consumed for a single test. My understanding was that they were lowered down the hole,

Hello my friends, As saying says, 'early bird gets the worm'! I start working at 7:00AM... yes, I know it is early in the morning. But it has its advantages: I stop working at 3:05PM (so I have lots

I have seen something similar in early 70s. That was in a lab of a reasonably fancy institute, but that lab did not rate real Tektronix, they just had a copy. I was there to install a printer

Hello Jose, I believe that 7A16P requires programming through backplane, otherwise it would not work. That is a plug intended for 7612 and 7912. You would need a plain 7A16 (without P). Regards

Oh, Walter, I have a bone to pick with you over some things that you said. But before that, let me tell you that it never occurred to me that this wiggling of display was done deliberately to protect

You know, you're right. It really is cheap for what it is. I guess it's because there's so much of it here (the largest volumes of it were made and sold here). Phil

I'm constantly amazed at how cheap this stuff is in the US... No wonder some of you have huge collections. -Michael

564B's typically sell for around $50 on eBay. Phil

Hello Ashton, My limited experience with bad electrolytics in Tek scopes was that there is no capacitance. I would guess, the problem was discontinuity rather then drying out, because failure has been

Hello Lyn, A couple of years ago I bought a 7904 and it turned out that one of those slot connector bodies was completely missing. Fortunately, all (needed) pins were undamaged so I could slide the

Right, this bargain of $80US will turn into $280US when you include shipping. Regards Miroslav Pokorni

Hi List There is one of those odd tubes that is used in the Transient Digitizers we have recently been discussing on eBay. The auction number is 1693061725. First time I've seen one of these outside

I'm glad you said that before I started trying to "fix" the focus on my 7704A. I really was thinking about it. I did, by the way, find a backplane that is being shipped to me so that I can attempt to
