Ozan, I just received a rejection of what I think is the latest email I sent off-list to you. I don't know what's happening with my emails but wanted to let you know what's going on. I don't know why

Hi Dave, I don't know what's up with my ISP. One other list member has had difficulties emailing me directly but it's a bit erratic. My own posts have started going to my "Junk" folder as well as many

Clark, Thanks so much for that link. I have not seen that one before. Downloaded a copy to my Tektronix folder. Thanks, Barry - N4BUQ

I'm in the process of troubleshooting a few things in my 7B50 and I notice the schematic shows a connection to the A15 pin of the rear connector and that connection is labeled EXTERNAL SINGLE SWEEP. I

I noticed the "little wings" on the Berg design and I didn't recall those being on the one I have. That's part of what prompted me to wonder if they were interchangeable. Thanks, Barry(who listened to

Jeff, I have a 2456B and I had to do the SMD repairs on it. I just wasn't sure about the 2465 and/or 2465A. Thanks, Barry - N4BUQ

Okay, Clark. Thanks for that information. Dave - If you're watching this, I'd like to see about getting a couple of those from you. Please feel free to contact me off-list if you'd like. Thanks, Barry

Does the 2465 or 2465A have the leaky SMD caps on the A5 board? I can't remember which models in that line have that issue. Thanks, Barry - N4BUQ

I have several scopes including a 453 and a 465B. I like both but if it came down to only keeping one, I'd keep the 465B. Thanks, Barry - N4BUQ

They might be close and the Berg might work in the Peltola socket configuration and, possibly, vice-versa, but I'm seeing differences between the two. Berg: https://www.digikey.com/en/products/detail/

Is the center socket for a Peltola socket the same as a minisert? I thought the miniserts are what was used for other component leads such as transistors, ICs, etc., and the Peltola is different but I

Hi Clark, Yes, that's it. One of the connectors on the horizontal amplifier board of my 7704A did not work correctly (intermittent) when I got it. My efforts to fix it made things a bit worse. It work

I wasn't surprised at a minimum order. I was, however, just a little surprised at the cost of the part. It's about the size of a grain of rice. I presume they haven't actually manufactured those in qu

I called and got a price. The center socket is $17.xx with a $30 minimum order. I guess I'll make do with what I have. Thanks, Barry - N4BUQ

I'd chalk it up to coincidence. The power supply boards have snubber networks consisting of C1018, R1018, C1016 and R1016 that are across the mains. Those caps are known to blow out and smoke like you

Hi Greg, Yes, those look like very nice units and have wished for one for quite some time. As you say, though, they can be pricey. I do think I can get it back in running condition by upgrading the el

Hi Dave, Unfortunately, it's the end where the tip goes. It took me a while of glancing at pictures to suddenly realize that was missing from mine. Thanks, Barry - N4BUQ

Hi Greg, I'm looking at a PDF parts manual for a 470 that's dated Apr,'96. On PDF page 20, Item No. 3 has a Part No. of B1030 and Part Name of "Filter Retainer". Unfortunately, just today I realized t

Yes, I would want to run it with filters in place. Unfortunately, the Filter Retainer (B1030) is missing and I'm not finding much in the way of replacements for that. I do have the A1030 but the A1033

I didn't notice much residue on the valves but I do notice that they're made of a white material and the replacements I'm seeing are clear. That might not indicate anything unordinary but I'm wonderin
