Always good to check the voltages rails first which I see you did. But I would still be interested in figuring out why that 5V rail is so out of spec (should be 5 +-0.075V). Also, I would check the

An acquaintance near here says he has some Tektronix gear that used to belong to his deceased father, who formerly worked for Burroughs. He sent me some photos of what he could get to easily, but that

First Post! Not seeing much by the way of editing tools for posts so I'll do my best. Test equipment: Hantek DSO2C15 oscilloscope Tektronix 2465A oscilloscope Fluke 87 V

I took a shoot in the dark an bought a non working 576 from a local classified section (something fell on top of it and cracked the aluminum bezel and sheered of a couple of the knobs on

I am glad to read that Dennis is doing well. I hope he has a great and speedy recovery. It would have been nice if there'd been a Tektronix 576 in the operating room. Dennis could've given them

From John with permission, personal friend of Dennis... Just got a call from Dennis. He sounds very good. On Saturday, Feb 10, they put in only one stent, the second being unnecessary. The one

It was amusing that the movie shows NASA engineers checking /sums of numbers /with their slide rules. The old-timers in the theater groaned quietly but audibly. -- Prof. Thomas H. Lee Allen Ctr.,

The probe compensation signal (referred to as the calibrator in the service manual) is different than most other scopes as Jon notes. It will produce a 5 cycle square wave on any sweep rate set

Jim, There actually were slide rules designed for particular specialties and occupations. A company called Hemmi (Japanese, and still around) made all manner of specialist slide rules. I believe they

I don't know if he's on this group or not, but I don't think he'd mind. If that doesn't work out, I have 2 that you could probably borrow for postage. Eric

Thanks a lot for the tip Eric! Is he in this group? Sorry I'm relatively new to this group and I know it has a ton of members. Do you think he would mind me emailing him? I've been looking for

I got a set of TM500/5000 cable-based extenders from Dan Meeks ( dan.meeks222@...) as a kit not sure if he has any left, but it might be worth contacting him. Eric

Winn BRAVO Great scope.... Check the SN, get servie manual and see the notes on A5 SMD cap leakage and NVRAM battery and replacement. the PROBE CMP of 2465B is proportional to the sweep rate.

This is just a guess, but how long was the earth connection for the probe? Not using a short earth lead is a classic cause of ringing. Cheers, David

I have a new to me Tek 2465B - a dream come true. As I was putting the scope through the paces, I discovered that the probe compensation output signal shows pretty significant ringing at time bases

Just use Ramtron FM1608 as pin-compatible replacement for DS.... it works.

I too thought the article was quite wonderful....and re slide rules. Walter and I talked about them a bit. great guy and sorely missed..i still use my 6 in slide rules ....my 18 in is bamboo and

I totally understand,? Dave!? Same issue here....? ? ? ? ? Jim FordSent from my T-Mobile 4G LTE Device

Yes, I had only bought once or twice from Sphere, but Walt and Susan did include some useful goodies.? Say, that NYT article mentioned slide rules made out of bamboo, and I'd never thought about it
