Re: 425 Mil vertical module needed....seeking
Hello Jack,toggle quoted messageShow quoted text
What you refer to as 425 Mil is, for correctness sake, a 465M or an AN/USM 425.
It confused me at first, as I didn't recall there was ever a 425 oscilloscope.
For what I know, the 465M is electronically similar to the civilian 465 (but even at electronic diagram level, there ARE differences), but, for the sake of assemblies or sub-assemblies, they're essentially two completely different oscilloscopes (i.e the boards are physically different).
As mentioned on this (http://w140.com/tekwiki/wiki/465M) page of the TekWiki website, the 465M is more similar to the civilian 455, than it is to the 465.
I can't really tell by how much they are similar, but you may be able to compare them by yourself by looking at the service manuals of both, which are available on the TekWiki website.
The page for the civilian 455 is here: http://w140.com/tekwiki/wiki/455
I don't know much of either (455 or 465M) but, coincidentally, there's a seller on a Brazilian auction site, selling the modules of a Tektronix 455:
I can't tell how similar those modules are (to your 465M) and if they can serve as parts donors, but if you find out that they may help, you can try to contact the seller, or I can help you with the purchase and shipping of the module (or the parts) to your location, for their advertised cost and shipping expenses to your place.
Note: I have no affiliation with the seller (and don't even know if I know them, since the auction site only reveals the seller after you purchase the item).
I normally wouldn't even make this offer, as shipping from Brazil is usually prohibitive and the parts are not even mine... But since you're so far away down under, I think that shipping from anywhere will be just as difficult.
Please let me know if you want my help, or maybe some other folks in the group will chime.
