Re: Tektronix 570 Vacuum Tube Curve Tracer on eBay

You hit in in one, Audio nuts, they can tell the shape of the getter in the valves/tubes in an audio amp by just listening to the wider deeper sound produced by the "correct" shaped getter. There is no fool like an Audio fool and they appear to have very deep pockets.

Tube traders and audio nuts use them for sure - especially for tube

Pardon me if this sounds like
Heresy, but what real world use
would have for one of these ?

I can see the "cool/nostalgia"
factor, but other than that, what
would one do with it ??

  For less than $200, I put together a Dennis Tillman VTCT board, and

I'm also not sure all my tubes and stereo gear are worth ~$4000 all
I KNOW my stereo gear is not worth that much!  I have the stuff to
build Dennis Tillman's VTCT and I have a 576 as well.  So even after I
a suitable tube tester, I am sure that all told I would have less than
$1000 in the whole thing.  It might not do what the 570 will do, but
95% as much and still test solid state devices as well.  You would need
have a serious desire or even more serious need for this thing in order
justify paying that price.  From the description, it sounds as though
thing is not quite ready to go as it is.  The elephant in the room is
getting it shipped to ones location without it being destroyed in the
process.  The seller does have a "Make an Offer" option as well.  This
be interesting to watch.
