Jeff,

Nothing wrong with doing a good job. My late wife worked in a bindery, where they built Courthouse record books from scratch. The skill, precision and quality of materials that it takes to build a book that must last for 100+ years is amazing. I still run a business that she founded, selling such books. I appreciate your point of view.

I have used Jeff's feet and can vouch for the quality of the 3D printing.

rick,

maybe I am a little OCD about this, but I also once worked in a print shop as a typesetter, back when such things were still things. Producing good looking printed and bound materials still gives me a thrill. If I can do a good job of this without breaking the bank, then I feel like I should.

I will add my endorsement here as well. I recently bought four sets from Jeff (our own Jeff Davis). They are excellent, 3D-printed replacements.

Cheers,
Tom

Bruce,

The cord wrap feet can be had easily enough from n0dy Jeff on eBay, $27.30 for as set of four (he doesn't list the 466, but it clearly uses the same feet as the 465 and 475). He used to sell on Amazon, but I can't seem to find his listing there now. I recommend n0dy Jeff's cord-wrap feet replacement at every opportunity as I am a happy, repeat customer.

I have a rear bezel from a 475A parts mule that is also part # 426-0970-00 and should fit the 466. It has a crack at one corner that has been repaired with epoxy, but is otherwise in good condition. I would be willing to part with it for a nominal fee plus shipping. Contact me off list.

WTB: Case ring for 466

greenboxmaven
 

I recently got a 466 to restore. The most important mechanical part I need is the plastic rim that goes on the back of the chassis to hold the case on. In the repair manual, It's called  "FRAME SECT, CAB. :REAR" and has a part number of 426-0970-00.  The feet which also serve as cord wraps are also missing.  Does anyone have any of these to spare? Thanks,

   Bruce Gentry, KA2IVY

I think you got that backwards Pins 1 thru 13 (bottom) are all the same Pins 14 thru 28 (upper) are mostly custom select as per units allow. Don't forget side A and B looking from the front A is on the right B is on the left of each connector on the TM500 series.

It's handy to have. I don't know if I use it enough, but unless I want to go to my copy/print place and pay them, there's no other way.
It's also handy for disassembling an existing "book" so you can copy a page, etc. Then, when reassembling, there is no equal.

You can buy covers for your "reports" but they are not the same stock, and not Tektronix blue.
It sounds like you are pretty OCD about this.

Re: New (old) 2247a enquiry

Thanks, that fixed it. Bit embarassing, should have read the user manual before looking at the service manual.


Re: SG503 question

Zentronics42@...
 

I can check the 2 of mine if that would help. I would suspect that they are close to spec if not in spec. I am curious if the 2 where the output is falling off are early serial numbers and the one you have the keeps going is a later serial number. Transistors in this era improved dramatically in quality and function. Now that I think about it I have no idea what my serial number is on the unit I have.

Zen,
Thanks for your reply.
Table 3-3 of the manual suggests typical LF limits of 4.70 and 9.09 MHz on the two ranges in question. My units get very close to, or past, these values before the output dies, so it may well be typical. A third unit I have just keeps going to the physical low frequency limit of the tuning knob. So I am not greatly concerned…but I was simply curious to know whether other users of these see the same thing.
In my (albeit limited, compared with many on this board) experience of Tek stuff of this vintage, the designs were usually not so marginal.
And no, I don’t propose to fiddle the tuning slugs: the limited SA capability I have suggests that the units are within, or very close to, spec.

We find many things to play with when we are sitting in COVID lock-down!

Re: Ballantine Calibrator manual

Ken Eckert
 

Thank you!

I have scanned and uploaded the Ballantine 6126M manual to KO4bb and BAMA. I have an early and late 6125B/C manual that is in the que to be scanned and uploaded...


Ballantine Calibrator manual

Bruce Lane
 

Fellow Tekkies,

You find the darndest things when you're cleaning up. In this case, it
was a clean reproduction of the operating and service manuals for the
Ballantine Labs 6127B O-Scope calibrator.

I've scanned it into PDF form, and am in the process of cleaning it up,
organizing the pages, etc. Once that's done, I'll post it to the group's
file area and make it available on my archive (and KO4BB's, of course).

You're welcome. ;-)

Re: Advice on fixing 2465B slow horiz sweep

Tom Lee
 

Sorry that I haven’t been following this thread closely, so forgive me if you’ve already explicitly verified that the vertical calibration has not been affected. But if the vertical gain is off by the same amount as the horizontal, though, that would point to a HV problem (in this case, a reduction).

Cheers
Tom

Sent from my iThing, so please forgive typos and brevity.

I suspect horizontal gain drift since that fits the symptoms and I don't know of any other problem.
I replace all the electrolytics in the power supply and everywhere else I could find one.
Just not sure if the horiz. gain is adjusted using a pot, (R860) or in the confusing CAL 01 procedure.
Anyone done that procedure?





Re: Paper Used in Older Tek Manuals

 

Thank you Toby and Ken for making those measurements. I have several reams of paper on order (28 lb and 32 lb because, as you say, heavier feels better). At the moment I'm using a blue 1/2 inch 3-ring binder for this manual, but I do intend to look into comb binding and good cover stock.

The covers used by Tek were 9x11 inches, and the paper has what feels like a plastic coating. For a one-off job I can cut the window by hand, but I'm considering a run of covers from a print shop that would do die cutting of the front cover window, and silver ink printing.

Greetings,

I used a Dial Thickness gauge AKA snap gauge on the pages of my 1960 Tektronix 517A manual. It indicated the page thickness at 0.0054 inch.

Examining several paper weight to thickness charts I found the following:

24 pound bond = 0.0050 inch

28 pound bond = 0.0060 inch

I did find a reference to 100 pound Coated Text Dull paper stock = 0.0054 inch

I did not find a reference for 26 pound bond.

I hope this helps.

If you have an original Tektronix manual and access to a local print shop, not an office supply store or copy shop, but a place with real offset printing presses, they may be very willing to help determine exactly what paper you seek.

Regards,

Ken
FWIW, I weighed 10 pages of a Tek 515A manual, I got approx 107 gsm --
approx 405 gsm for the blue covers. Of course heavier always feels
better (I would try at least 120 gsm equivalent).

I'm resorting to printing one of my own manuals (which doesn't appear to be available in hard copy from the usual suspects, and is thankfully relatively short). I've got it printed now on normal 20 lb paper, but it's much flimsier than the original manuals I have. I'm looking into making a much nicer copy with blue covers and comb binding, and would like to get closer to the quality of the original article.

Does anybody know what weight of paper was used to print the old manuals? If not, I guess I just buy some reams of heavier weight papers and see what feels right.
