Don, that sounds like some very good advice. I'll look for replacements for awhile before I disassemble it. By the way, guys, I'm going to sell it either way, whole or in parts, so if someone has the

Er - OK, Wollongong is in Australia, right? So $165 is Aussie dollars? That would make it around $80US or around ?60UK. At that price, I'd snap it up. If I wasn't on the other side of the planet, that

Funny you should mention that. It is a long time since I used a 4-bay Tek scope, but I recall that the readout vibrated up and down a little too (it was either a 7704 or a 7904 - I forget which now).

To whom it may concern ,and for what it's worth, I found a 564B scope for sale in the "Cash-Mart" second-hand shop in Wollongong a couple of days ago. They were asking $165 for it. I don't remember

Okay, guys. Here's the deal. I have the 7704A working but I need some advice. Slot 1 is unusable and slot 3 is unreliable. All the switches and controls have been cleaned and work smoothly. All the

My 2 cents: Sounds like you're so close now to having it fixed, I would think you'd want to take the last steps. You've narrowed it down to cracked or missing backplane connector shells. This is

If it works and If the shipping is low and If you can trust the seller, -- it's a good price.

Hello! I wonder if the above mentioned combination will work fine. I have been offered a curious (to me at least!) setup: 7904 + 7A16P + 7B92. It has some trouble with signals over 100MHz (it seems a

Stan I forget to look for a part number. What you said sounds right to me. I like the idea of a coaxial relay. Are they used in anything else? I'll probably be asking about pinouts later. Thanks.

Hi Lynn, After taking a look at the eBay pictures, I have to admit that in my 26+ years at Tek, I have never seen this thing. Tek made a lot of LARGE systems of 7912's (digitizers, like we have been

I'm going to be doing some 7704A power supply troubleshooting this evening myself. If you'll tell me everything you know about your problem, I'll keep it in mind while I'm working (or while its fresh

I have a very clean 7704A with a sick Power Supply. Anyone have one they will part with ? Thanks, Dick, W1KSZ

I learned to use an oscilloscope in Tech School at Lowry AFB in 1966. The next time I used one was last December - over 35 years later. You forget a lot in 35 years. I have scopes. I have probes. I

Hi, I recently purchased a DC 510 module which works fine except for an occassional tendancy to go haywire displaying random garbage and only intermittently displaying the correct value. When the unit

I've decided to pass on the digitizer. I've bought enough "toys" already (toy=something to take apart to see if there is anything useful in it), including an HP1630D. Right now, I have a 7704A

Once I had a little problem with my septic tank (sewerage system) and needed to get some air into it. I went to the local pet shop and bought a fish tank pump that did the job just fine. However, they

Hello! I wonder if anybody uses that digitizer... If so, what do you think of it? Best regards, JOSE ---------------------------------------------------------------------- 73 EB5AGV / EC5AAU - JOSE V.

Hi, here is some hands-on experience with buying a 7912AD at ebay: Half a year ago i got a 7912AD at ebay for US $ 50. It was shipped from US to Germany by USPS surface for about US $ 90. When it

Lynn, If you are talking about the 7912, it is good for making extemely fast, single-shot measurements. Very handy for things like nuclear explosions . . . when you need to catch the EMP on your
