Really? What’s bad about it? The power supply in my 577 seems to be powering it just fine, and has apparently been doing so since it was made.

I have a 577. I haven't had to repair that part yet. What bad about it?

Hello All, I picked up some really cheap ($3.95 at Electronics Goldmine) displays that work in the TDS2000.  The problem with it is that is looks like the backlight is too bright.  The only way

Wanted: 067-0525-00, 067-0525-01 or 067-0525-02 Hi does anyone have any spare of these BNC T cables (must be better that just BNC T and two short cables). Ideally in Europe as postage from USA has

Hi all, a quick update: I added pictures to the album with more information on this scope. As you can see in the pictures, there is a small scratch on the front where someone before me removed a

All that I know - I was hoping there might be something like a CLIP or similar floating around. D.

Hmm 555. Interesting topic. The scope that was the last gasp for tube technology. The top of the oscilloscope food chain. The end of an era for sure. I have worked on and with the 555 since 1966. As

Seeking suggestions on trouble shooting. Main Sweep (A) will not trigger. Did the procedure found in the SM, page 4-16, maintenance section Section 2 Removed Q572 and checked dc collector voltage

Does anyone have a datasheet for 7L5 U830 on Diagram 8 (PN 156-0117-00)? I have always suspected a timing race of some sort between the sequence and rate of turn-on of the 7854 power supplies and the

there is no other the type of old fashioned service manual that you are looking for, Tektronix stopped making them 25-30 years ago. you cannot find that type of service manual for any tek equipment in

I've just returned to this, I have managed to secure the front of the switch using a tiny self tapper, but this doesn't work at the back because the actuating shaft of the switch protrudes too far and

I once had a student, who said "oh look, old technology". I'd brought in a 7704A with a 7CT1N for a demonstration of transistor curves. He can't fix the new stuff. I can fix the old stuff He can't

The main power supply in the 577 Curve Tracer is one of the worst I have ever seen. Does anyone know of suggested modifications to make the power supply behave better???

Ernesto, Got a kick out of your post. I went a step further. After retiring as an Aerospace Engineer for 50 years, I ended up building a huge electronics lab and a CNC machine shop in my home. Not

Well the only one I found was at Tek.com and isn't a proper service manual - darn it only just tells you how to open the case, and as for hoping for schematics ... If you know of a "proper" service

Hi Jim, Yes, we engineers are pragmatic people, efficient problem solvers. When after 12 years of being away from electronics I saw the need for a working oscilloscope I initially thought about

Hi David, Check on google search. Faith

Tom's mention of using a Type O as a trigger conditioner is interesting. I'd appreciate hearing more about this. Modern scopes have menus for this but they are opaque. The 556 is a wonderful scope

Hi Albert, Good that you noticed, it's probably because I hooked it up to this wonderful Windows 98 machine... No battery backup in that machine, but it does have a SSD ;-) I will check and update
