Ian,

Delighted you have the scope fixed despite my best efforts to cause confusion. No, I am not a night owl, I live in the UK.

If you browse around here and elsewhere you will find the general recommendation when replacing tantalums with aluminium (UK spelling!) electrolytics to approximately double the capacitance to ensure low ESR so 2.2uF at 100V as and when you can get hold of one.

Enjoy your now working scope,

Roger

I bought a scope from Mr, Schonfeld as well. I have read some really shady
stories about him in this forum after I bought a scope, so this was a
concern for me. My purchase was a TDS360 and it was supposed to have new
NVRAM installed. The scope worked fine for some time after it arrived.
However,after a few hours of operation, the display quit working. I will
say that contrary to what many have said, I found that he responded and
solved my problem with a minimum of drama, up to and including replacing
the defective scope. I opened the original scope and found that he had
indeed done the work that I had originally bargained for (New NVRAM was in
place on a socket in the board), so this was a good sign. The work that he
did appeared to be very good, as far as I can visually determine. As far
as Making 2445's into 2465's, that is something that I am not in a position
to speak about. But I can say that my particular transaction with Mr.
Schonfeld was very satisfactory. I am breathing a big sigh of relief.

A BIG thanks for everyone's help!!!

Just an additional story here.
You all remember that I bought this scope from Alexander Schonfeld in
California (ebay username - 2465b), who up-modded the 2445B A1's frequency,
without telling the customers.

Well, I got in contact with him, and I suggested to him that the right
thing to do, would be to send me the new IC's free of charge.

He did, so I do say that the man is making amends in a small way, and I
appreciated that.

Subject: Re: [TekScopes] TekWiki Helper Idea. Brainstorm or Washout?

Michael Terrell had an interesting idea that might save us time but as near as I can tell it would only make a lot more work for Kurt at TekWiki.
Michael's idea was to list the options for each model on TekWiki.

The more general question is what would it take to list every option for every instrument on Kurt's web site. I know Kurt doesn't have the time. He has a full time job already. I doubt anyone on this forum has that much time to spare. I don't.

That started me thinking what it would take to do this. There are 40+ years of catalogs from 1965 to 2005 that Kurt roughly covers the products from right now. Each catalog has anywhere from 100 (the 1960's) to <1000 instruments (the 2000's). Each description has a section at the end with the options and their descriptions. The option number and description would have to be logged, then incorporated into each of Kurt's web pages. My best guess is it would take 1 man-year of work on the part of a college student majoring in electronics.

So here is my question: How much could we as an organization raise to give Kurt a helper to really speed him up? Is this even a possibility?

Hi,

Thank you for that Dave ... key word "experience" .... well, I am gathering it slowly ..... :) I haven't totally grasped the above yet ... but I will.

Some good news ... my 'beast' is now running ... traced the 'short', or more correctly, the very low R across the +50v supply to Ground, all the way to the Vertical Amp board .... and then to .... yes, you more "experienced" TekScope people know the answer already ... C492 .... tantalum(?) 1uF 50 v cap across a +50v Supply .... mmmmm .... in my el cheapo scope maybe ... but in my Tek scope ....????

Replaced it with a 1uF 100v electrolytic ... and she has been running for an hour or so already. Perfect traces?? .... no .... but all functionality seems to be there. I will let it run for awhile to flush out any more issues ....:)

I haven't yet had the time to search this SIte, but I'm sure that it contains some suggestions for replacement caps for these tantalums .... there are 4 on this board. I will be away for a few days, so I will tackle the next phase of getting this Scope running properly then.

A huge THANKYOU to all those who responded, and lurked, for all your assistance. I like to do things like this slowly and learn heaps along the way.

Re: TekWiki Helper Idea. Brainstorm or Washout?

Kurt Rosenfeld
 

I agree that it would be great to have a list of options for each instrument. And I agree that the information is not easy to find.

I'm happy to make a Tekwiki account for anyone who emails me and requests an account. This formality is just to keep out the bots that post junk on wikis. (This has been a problem in the past.) Some people in the Tek community don't want to mess around with the wiki directly and, instead, tend to email me corrections and things to add. That's fine, too.

The 7603 page (http://w140.com/tekwiki/wiki/7603) is probably the best overall Tekwiki page, currently. Of course, it could be better in many ways (e.g., it lacks history about the instrument (e.g., who designed it), it lacks discussion of the circuitry, it lacks context in terms of how it compared with other models, etc). But it is pretty good with listing the options.


OT: Sometimes old-school is still the best

Ed Breya
 

As I've mentioned a number of times, I've been cleaning out the garages, deciding on what to keep and what to get rid of, and organizing projects - setting aside stuff to really keep, and boxing it up together. One project that I have intended to build for some time is a new drill-runner - an AC-powered PS to run various battery-powered drills and other tools, for high demand use such as doing lots of heavy drilling and screwdriving, and saws, where the usual battery operation runs out of gas, so to speak. I long ago standardized on the Ryobi 18V ones, with all the chargers and batteries, etc. Of course, over the years, the NiCd packs have crapped out, and I've gone to the newer Li types. This has left me with lots of old tools and dead battery packs to experiment with.

A few years ago, I built a version of this with an an old 12V battery charger that used a CV transformer and put out about 15V at up to 40A, to run heavy loads like saws. I hooked up a heavy cord from this unit to an empty battery pack husk, to run tools directly and continuously on AC power. They didn't go very fast due to the lower voltage, but had lots of torque available. Of course, this is not as convenient as batteries, with a big cord hanging off that could only reach so far, tethered to a 30 pounds or so box.

More recently, I had planned to make a new one with closer to the proper voltage, using a couple of open-frame switching supplies - a 12V and a 5V stacked to get 17V at 20A, and they could be adjusted up a little to land near the nominal 18V. I also experimented with a bunch of old identical laptop power packs rated for 20V, 4.5A each, in parallel. I found that the SMPSs all fell short of the desired characteristics for powering a variable speed DC motor drive that needs high start/stall torque - they OC tripped out so easily that they were useless. I would have needed lots and lots higher rating and complexity to go this route.

So, I decided to try old-school, with a typical transformer/rectifier/capacitor combo. The trick was to come up with the right size for everything. I have three big old open-frame OEM 5V/18A linear supplies that I didn't need, but couldn't junk out - they're just too nice to get rid of. These have the usual push-pull center-tapped winding to make about 11V (no load) to have enough overhead under all conditions for the 5V linear regulator circuits. The transformer is probably about 300-400VA. I unhooked the regulator circuits, and ran it into a full-wave bridge and a couple of 15,000 uF caps paralleled, and low and behold, it was a beautiful match to the need. It's about 22V open-circuit, and drops to 17-19V with "typical" loading, and down to around 10V at heavy/stall range. I didn't measure the output current, but did monitor the input power - it could go well over a kW input (briefly), and I could not hold the drill chuck stalled with my hand (bad idea - now have some blisters). It's about the same or better performance as using a battery, and just doesn't quit.

This simple circuit, with appropriate V and I and thermal protection, will be an excellent PS for 18V tools, and can provide high surge capability as well as continuous regular output - as long as the cord reaches. Sometimes, old-school is still the best.

Re: 7603 15+ rail dead. Options?

Dave Hills
 

Is there any good reason why I can't simply obtain +15 v from a 2 amp 15 volt regulator chip — like an L78S15CS — and ignore the +15v sense line?>>
Three that I can think of.

First, you will disrupt the power-up sequences of the various DC supplies. Many IC's and discrete circuits don't like seeing positive
voltages before the negative rail comes up. May or may not be a problem, but you have to ask why the various regulators are sequenced as they are?
Second, what will happen to the calibration of your plug-ins when +15v is outside the limits of the original design and no longer tracks the -50v supply? Lastly,
+15v current limit, will something go @#poof--!! if your supply is not limited to the same value and function as the original?

Also, a thin layer of epoxy bonding together the flat sides of a pair of TO-92's is would be my choice over thermal compound.

OK. A lot easier to do than explain, but I'll give it a go. No data sheets, just calculations
based on some assumptions derived from experience.

First make some assumptions based on observed conditions:
Collector current very small, based on large emitter and collector resistances.
Base current negligible for purpose of estimating operating points.
Vf CR861 ~ 0.6v, assuming a small signal diode.

Step 1) Simplify the circuit by setting the +50 v sense feedback voltage (+0.7v), to zero and replacing
the divide by two network (R858 & R859), with a 20K resistor and a -25v source in
place of the -50v sense.

Step 2) Calculate the loop current through R864, CR861, and my 20K equivalent resistor.

Step 3) Calculate the base voltage for Q860, Vb = ILoop* R864 = -12.4v.

Step 4) Calculate the emitter voltage for Q860 & Q863, Ve = (-12.4v - 0.6v) = -13.0v.

Hi Jafinch, I see the good thing about having the Manual because of the 500 Projects in it. You can step all the way through it to learn electronics or select from the index the ckt you want and flip to the page for the schematic & theory notes !. You can use any peg-board , but the Mini-Lab comes with all the support circuity : p/s, /osc/ leds/ switchs/ speaker/etc . Open the Lab on your desk and POW, you are ready to assemble a ckt into it and run it . And, Oh Boy , I plug in my Tek 212 Mini-Scope and look at all the signals I want . Where Oh Where , has this Lab/ Toy been all my life ?;

Now, the manual is 368 pages of 10x15 sheets ... Copying that to PDF is too big a job for me. Your costs would end up too close for what you can get the Mini-Lab and get the manual with it ! It is false economy to go through that work when the book is readily available ; and there may be copy-right issues.

My older catalog of ramseykits.com has an excellent full page photo-article on this 500-in-1 kit.. Soon as I saw the photo I said;Whoa, that's for me and bought one !
