Tektronix 570 Vacuum Tube Curve Tracer on eBay

Gee. Only ten bucks less than four thousand dollar$. Too bad he doesn't have two - one for spare.

When the prices get that high, at some point you need to ask yourself how
much it would cost to build one from scratch!

For less than $200, I put together a Dennis Tillman VTCT board, and modified my Hickok Tube Tester to use with my Tektronix 575 curve tracer.  I also made the Daniel Schoo designed triode and pentode adapters for the Tektronix 576 Curve Tracer at work.  
I'm also not sure all my tubes and stereo gear are worth ~$4000 all together.    ;)

Maybe a lot of people have a car that cost less. And that is not a BIN price but an auction. So the seller clearly hopes to get more than the 4K for this one.

One time I was delivering an oscilloscope I had sold locally to a guy. When I walked into his office there sitting on a table was a pristine 570. I stupidly blurted out that “those are worth over $2000!” But I didn’t have the money to buy it so I left. But after some more sales I did have a bit of a nest egg and went back to see if he would sell it. When I asked him what he would take for it, he said “$2000.” Nice going. But I did buy it and again stupidly later sold it. I would like to still have it just to own it. I wonder if he will get bids.

Ha, interesting story. Yeah, I didn't even notice it was an actual auction.
I would be surprised if anyone bids on that, but I could be wrong! Will be
interesting to see what happens.

A long time ago in the early 80's the Massachusetts hams ran an auction at Honeywell Inc
in Billerica. You could bring your old electronic stuff and they would auction it off. It was
great fun and always well attended.

Anyway, one guy brought a 370 to be auctioned. As he wheeled it in on a cart the crowd
chuckled. When it went up for auction it sold for $1 and the auctioneer had a hard time
getting even that! Between then and now, what a great return on that investment.

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 buy 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 likely 95% as much and still test solid state devices as well. You would need to have a serious desire or even more serious need for this thing in order to justify paying that price. From the description, it sounds as though this 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 will be interesting to watch.

Is there a modern version of these curve tracers? From what I have seen the 300 series seems to be about the top end. I know you can get the same functionality today but you need 2 X $10,000 SMU's, and a computer, and software so call it a $25,000 setup though given the catalog price of the 576 and the 300's doesn't sound so bad now that I say it.

I have been looking at sales of Tektronix 570s, mostly but not all on ebay, for a long time now. All of then have had an asking price of around $4k.

You forgot "Sucks More than Usual" :-)

But I'm not sure what the advantage of a 570 is over something like
the Utracer3+. If its voltage, I'll mention rumor has it, Ronald
is working on a v6 that'll do 1KV plate & screen....

(Not that I'd ignore a 570 if I found it lying by the side of the road
mind you...)

Many of you are not familiar with what the 570 is worth to a lot of people. His starting price is not out of line at all. If past auctions are any indication it will sell for over $5,000.

Hi David,
It's not a rumor. It's a fact. I concur with Craig - the uTracer6 looks like it will meet the needs of almost everyone.

The current product, uTracer3, is an extremely impressive product and proof that this guy knows what he is doing. I thought this was brilliant when I first saw it 2 years ago. The only improvement I thought it needed was higher plate voltage and current and a greater range of grid voltage. It looks like that is the minimum improvement he is working on for the new version. I'm sure it will have other capabilities as well.

I'm not sure why he thinks there is a need for so much positive grid voltage but that is probably because he didn't realize there are OpAmps that can work off of asymmetric voltages. That would let him increase the negative grid voltage range by reducing the positive grid voltage range the same amount. For instance the -100V to +100V range for the control grid would make more sense if the range was -150V to +50V.

uTracer6 weblog online

Dear uTracer friends,

Let me start by wishing you and everybody dear to you a great and above all healthy 2020!

The uTracer3 has been around for a number of years now and over time many people have asked me for higher voltages and higher currents. It is not so easy to come to a design that hits the sweet spot between performance on one hand and simplicity on the other hand. I think I am now on the right track for a well-balanced design, and I felt confident enough to start a web-log about it. The target specs for the uTracer6 are 1000V @ 1A for anode and screen, and a -100V to +100V range for the control grid. The coming months I will add chapters to the blog as the work progresses.

Once a year I ask people who have built a uTracer and who are satisfied with it to send me a few pictures and a few lines for my testimonial page. If you have not done so, please take a few minutes time to do so. it is highly appreciated!

warm regards,
Marie-José & Ronald

SMU is source measure unit. From the KB i saw from Keithley there is a way to do curve tracing with the 2461 and the 2471. It requires 2 units at $9,600 each an interconnecting cable cat 5 on each out to a computer which has the Keithley lab suite software. I think the setup is one SMU for collector voltage and the other controls base current. The units sweep some set points then the software plots and excel style graph from the measured points. There was a KB that Keithley put out on how to set everything up I will see if i can dig it up.

Sell matched pairs of 6L6’s on eBay with the tag “Matched using Tektronix 570” for bonus (read: marketable) audiophool “authenticity” and “vintage analog" cred.
