I am so happy that nobody faked my 547 scope. So far, all parts on in match exactly what the service manual says. Ernesto

No, Chuck, you are not a dumb engineer, you are a smart engineer!  One of the greatest assets this group has, no less.  Thanks for putting in your thoughts once again.Jim FordSent from my Verizon,

Chuck, Thank you for the explanation. As I said I'm not interested in performing this modification. I just find it interesting from a technical point of view. It's crazy that the seller is getting

Just a minor note on the 2465 (non A or B) fan... Starting with 2465 serial number Β050100, the Siemens fan was replaced with a standard 12V axial fan (Manual Change Info from 9/19/1985). I've had

You misunderstand what Chuck was saying - he was saying that's what the fakers do. He would never countenance that. David

He's the one selling 2445Bs faked up as 2465Bs David

Wow, that seems like a lot of work to sell a fake, especially when you can pick up a 2465 for $250-350. But, the low priced ones need some careful due diligence. Look at the photos. If the seller

Chuck, my Tektronix is 2465 DMM - is this the 2465A version? Can I do what you recommend in step # 2 and 3? Thank you very much for your help.

Ernesto, you are a wealth of information!!! Thank you very much again.

Briefly, because I have discussed this before: 1) Replace the labels that say 2445B with labels that say 2465B. 2) Add a jumper to the A1 motherboard connector that goes to the A5 controller.

Hi Ross, From a somewhat different angle than the other comments, if you like to know what is inside your beloved instrument, the 2465s come with the excellent manuals in the Tektronix tradition. I

You might want to check the archives for this group to see all of the kurfuffle that "2465b"'s "frankenscopes" (2445B scopes with 2465B labels) have caused. -Chuck Harris stevenhorii wrote:

I think he is also the person who sells or sold newly made 2465B badges for the handles... Only, they show up not just on real 2465B's, but also on rebadged "upgraded" other 24xx models....

I personally like the A. I've used scopes of various flavors for 50 or so years (my first was an EICO kit I got for my 12th or so bday, 1 whole Mhz). I have a 2465 and a 2465A. Wouldn't mind trying a

Don't go near that guy. I am one of many who have been screwed over with one of those high dollar rebadged units. I tested the bandwidth and checked the innards and it was NOT a 2465B. Just a bit over

Hey, isn't that the guy who fakes 2445's as 2465's?  Just sayin'.Jim Ford Sent from my Verizon, Samsung Galaxy smartphone

Hi group, I am sorry for asking, but curiosity has got the better part of me. How is it done making a Frankenstein 2465 out of a 2445? Not that I'm planning to do it, I already have a 2465CT and a

Can you take a picture of the front of the scope so we can see how you have it set up?
