The best toys are always the ones you build yourself. This reminds me of the country western song about the guy who works on a Cadillac assembly line and builds his own Caddy by bringing home parts

I have picked up a nice clean 7704A mainframe that has a power supply problem. The first thing I did was check the +5v Lamp voltage and it was very low (~0.8v). I looked at it with another scope and

Thanks. It looks interesting but I'm afraid I've already bought enough interesting stuff to keep me busy for a while. Thanks for the info? I'm going to let it pass.

It shows up as a raster generator. 16-24 line pairs. 300-400 dots. 1 volt output. The military paid $5800 each for them. It sounds like it may be used for adjusting Tek displays of some sort. Jim

I saw the note from Dean and it brought back memories. I worked for IBM in 1957 to 1959 as bench technician. I used a 541 then a 545. I really fell in love with the 545 and wanted a scope for home use

I remember this unit well. Back in the late '70s I used this beast to capture sub-ns detail on laser pulses. The total pulse length was 30ns or so, and the repetition rate was 30Hz - so even a 7103

I believe the whole system was called a DCS (Digitizing Camera System), and included the black/white video camera, C-30 style camera adapter, a long pc board that plugged into a luggable IBM pc, or

Hi David: I use a variac with an AC ammeter in the load side. Temporarily replace the 475 fuse with a 4 amp one and adjust the AC voltage until about 2-4 amps flow into the scope and wait about 15

Reed, I'd love to see the picture of your "545D".,... I have a "B" version. Thanks Chuck Junction City, OR

Sounds like you have a short past the PS. Try to get a manual if you don't have one before you pull off any connectors. If you do get brave and pull them mark them first. If the ticking stops after

Hmmmm... I was offered locally (I am in Spain and it is really difficult to locate good Tektronix gear so Lavoie is yet more difficult to find) a Lavoie LA-265A for about $110, along a CA plug-in. I

I have one of those things in my collection and it will be interesting to see what I find wrong with it when (and if) I ever get around to it. I also have two clones made by Hickok and I have looked

During my time in the U.S. Navy at USNAVSECGRUACT Sabana Seca, Puerto Rico in the test equipment cal shop, I got to use the Lavoie "faux- clone" of the Tek 545 every day for two years. I finally got

Are you the antique radio Marc Ellis, Marc? Let me know: dhuster@... Dean

I picked up this TEK Video Camera (mounts on Scope face). Does anyone have a manual I can buy or copy ? Or have any info on this camera ? Thanks, Dick, W1KSZ

Hi list There has just been a Tek P6156 probe gone on eBay - brand new - for a BuyItNow price of $5. Have a look at item number 1685282338. It sold in about a nanosecond. A 10x, 3.5GHz, 50 ohm passive

The new scanner may be more vulnerable to overloading caused by too much signal from a nearby transmitter. For many years now, the trend in all types of receivers -- not just scanners -- has been

I wonder if the aerial connection could be inducing hash from a switchmode power supply (if it has one). Is there any difference in earthing between the two sets? Don Black. james89es wrote:
