Well well well, Q4566 open. A depletion mode FET, and I couldn't find one. I look at the print, I think about those 2N7000s I got. I look at the print again. I think about the 2N7000s again. All they

I have recently acquired a spare CRT for my 2465BCT and am trying to understand the markings as follows: P/N?: 154-0850-00 S/N?: 149403 Other?: 41-91 Is this possibly a date code, perhaps

" Or, you could just slide the blue filter up, and out at the bottom and remove it. The gorp might be just there. " Thank you Chuck. I did not know you could do that. It was rather easy and it cleaned

Ok Fabio...finally I see it ...well some of it....Is that Brazilian site related to Bert? There's no contact detail for him. Can you assist there?...The vertical on the Brazilian site is "identical"

Hi again for your interesting information. Amongst it you wrote "But Bert already chimed in that he has a NOS 465M module... so I think you already have a good lead" I didn't receive that....was it

I found one more fast part. If you happen to have an MPSH55 in your junk box, or you can get one more easily than a BC556 or KSA992 (Netty Electronics has a few dozen left), it will do great with

Hi Fred, Make a note to yourself - Craig is much smarter than me for several reasons: He knew the answer right away; He was able to describe it in one paragraph; He had a better way to test this with

Any digital scope is a sampling system, so it looks at a waveform, does an average during the sample period, and then ignores the signal to the next sampling period. Pretty much as long as you sample

hello all similiar hi my usual problem with the tektronix 475 voltages as of now: 50v 33 v 50v a reg 67 105-160v 132 + 15v 5.53 5v 3.25 -15v -8..8 -8v -5.12 110v 86.4v What could be the cause? if you

Okay, I think the analog would be more useful possibly in trouble-shooting, but I am so experienced in the TDS3000 series, that I love trouble-shooting with it, plus I know the equipment so well that

They aren't that bad. They can do well. Not really useless, IMHO. Probably is

Craig, Thank you kindly for those detailed instruction, which I have printed out. Perhaps later today, I will follow them and get that puppy cleaned out and generally look inside for cap leakage. Dave

" The 2465B does (should!) have measurement cursors for time and/or amplitude but you have to enable them to see them. Nice dumpster find! " Yea, I found them, before putting it aside this morning to

The knobs don’t have to come off. This is how I do it all the time. I usually take the case off when doing this but the scope needs a front cover which you may not have. But it if you set the face

There is a plastic trim strip on the top of the bezel that snaps off revealing some additional screws. Manuel

Same thing with logic analyzer probes, scope probes, and anything in general. Ran into a bunch of P6201 active probes that were "decommissioned" by cutting of the 40 dollar LEMO connectors. I

Hi Dave, The 2465B does (should!) have measurement cursors for time and/or amplitude but you have to enable them to see them. Not sure the exact buttons that do that but it should be easy enough to

I got a 2465B, 400MHz, while dumpster diving a while back. It seems to work perfect. I do not have a lot of use for an Analog scope, (especially w/o GPIB) but if I decide to sell it on EBAY, or even
