David, So sorry to hear about your Tektronix 576. Reminds me of my Tektronix 531A situation a few years ago. Seller wrapped the scope with 1 layer of bubble wrap and then wrapped it with cardboard box

Hi Steven, I do not have a 547 yet myself, but from what I have read is that one of the main signs was that the trace would dim out making you turn up the intensity until the trace gets really dim and

Hi Jeff, I am glad that I was able to contribute this this forum. I would have to say, in my opinion, since you started to clean that section, you should keep cleaning it until it is spotless. I have

Hi Jeff! Great to see you are working on your 533A! I have one as well, but it's in really bad shape on the inside. Those 2 back strips is perfectly normal. My 535A and my 545A is like that as well. I

I know that we are way off topic, but since we are talking about previous shipping experiences, FedEx is my worst one. Any Tektronix scope that was delivered via FedEx has been totally destroyed. The

I have tried to use LED's for my 500 series scopes and they didn't work out very well for me at all. I really wanted to try it for my RM565 as that scope has a bright blue CRT and with a white graticl

Hi Jerome, Harvey is right that Tektronix scopes do not like ripple. In fact, a lot of problems is due to the power supply issues. Just my 2 cents, replace one can electrolytic at a time. Some can be

Hello Jerome, If you are thinking about recapping this, I would just focus on the electrolytics first but of coarse that is just my opinion. Tek 547 scopes are newer and I have never opened one up bef

Hello everyone! I am happy to see that Jeff has rescued that 533A scope! I have one myself, but it's beyond repair sadly to say. As far as transporting CRT's goes, for the most part, they are a little

I binged watched Stargate SG-1 a few weeks ago, and I did see briefly see which I believe to be a RM503, in the intro for an episode in season 3. Beginning of the episode started in Major Carter's Lab

Hello Joe, I use a capacitor checker from Mr. Carlson's Lab, and that works very well. As far as your list of capacitors goes, I have had very good luck with Good-All capacitors! I have checked many o

Hello Joe, First off, I just want to say that's great that you got that 575 up and running! The only thing that I would say is not to rely on your tube tester for testing tubes. Tektronix says it over

Hello Charles, I do not have a carry handle for your 564, as both of my 561A's, 564, 503,504, 531, 535 and 545A needs handles as well. My 561A's and 564 have it the worst as its down to the metal stri

Hello Chuck, My RM565 does have the aluminum can, but so far, it has been working like a champ so far. I am assuming that this will eventually fail. I do hope that it will hold out. But both of my 561

Hi Jared, very impressive! Almost makes me thinking getting some of the TM500 series! Michael, Jared stated that PCBWay did the boards and I am very impressed with the boards. Has me wondering if I co

Bruce, I have sent you an email. :) Brenda

Hello Bruce, I do have not 1 but 2 Tektronix 3B4 time bases that I would be willing to part with. 1 of them is functional as far as basic use goes. I am not a professional by any means, so I don't ful

I have 3 Heathkit IM-28 VTVMs that I love using, just because they have that cool factor, plus it seems like they are quicker to respond to changes in voltage compared to a DMM. All 3 of mine had to h

Hello Dave, The 3A1 plugins that I have come across ends up not only the 6DJ8 tubes missing, there are 2 8233 tubes that end up missing as well. There are 4 7586 nuvistor tubes in the front end, but s

Hello Grayson, I am interested and I have sent you an email. Been looking for one of these for a long time! Brenda
