Are these good for use in vintage audio?

Vishay Angstrohm Hermetically-Sealed Metal Film Resistors

Well, this says where and why you might use them:-

Overkill for domestic HiFi I would say, a very quick search revealed they are about $10 each.

I was given a bunch Of these NOS from An old aerospace company changing hands. And more than a few resistors in my sansui restoration were drenched in the dreaded glue.
I’ll browse the pdf tonight, thanks.

Yes, I think so too. Probably overkill for mil-spec too (no joke, this is really mil-spec). Most likely suitable for hazardous environments with the space and aeronautics industry in mind. If I could afford all around $10 resistors - I would, but heck, I got better things to do with my money.

It is the Sansui forum. Your vintage Sansui deserves good parts

I did put an aircraft quality type of loudspeaker relay in my Sansui AU666. (top left in the picture http://www.gerardslikker.nl/au666bottom.jpg )

Now it can fly, believe it or not.

ABSOLUTELY! This burgundy block of steel & pcb’s has been entertaining me and possibly two? other Owners for 46 years! She’s getting the good stuff for sure!

Well then those may turn your Sansuis into Rocket Sansui's

Too the moon....

I see that they are encased in their own atmosphere of Helium and
If they were NASA approved they may be super stable from -274 to plus 200 F
so they can't be that bad.

.....And the price was right.

Well hey, This is the kind of technology that after 44 years has taken the Voyager 1
Spacecraft past/across the heliosphere and carried it into interstellar space (August 2012).

So somehow it would seem only fitting to put them into one of Sansui's finest
and then you could tell everybody how your Sansui has the same resistors that carried
the Voyager 1 spacecraft 14.1 billion miles and after 44 years Voyager still works too..



.

MINUS 274f ?, +200f?! Well,I do live in New England.......
Another plus is it’ll be a WHOLE LOT easier on my back with all the helium. Just tie a string to it & float it from room to room-When neighbors to my left complain, float to the right

Metal films are the lowest voltage noise resistors.
But those are way overkill.
On the other hand, if you have enough, and they fit, then why not?

 

[joestcyr]

Should be good in the signal path & I gotta say they look nice too, glass & gold. I am astonished everyone here agrees they are hi end resistors. Thanks to all!

no question that they’re high quality, high reliability parts.
But “ hi end” means different things to different people.

HOW TRUE!
