@med, well done you jammy git, now you know why Jim Williams always said that when it comes to Tektronix scopes, the problems are nearly always down to Tants.
Old stuff is good stuff May or may not be any good 'last used in 1975' but will be added to my good working pair I already have.
Crusty and slightly dangerous if consumed.Very nice. I wouldn't even know where to look for them ...I blundered into my four at a school for 16-18 year olds that was closing down.
Even the ones from 1949 are well within spec: https://entertaininghacks.wordpress.com/2016/12/28/a-weston-standard-cell-an-introduction-to-voltnuttery/
Selling them via ebay would raise two questions about shipping:
- functionality: not only the glass envelopes but also the crystal electrodes are fragile, e.g. keep upright, don't shake
- legality: mercury and cadmium aren't healthy when they escape, and mercury vapour makes aeronautical go white when they know how it changes the properties of aluminium in airframes

A while now. *Bah-dump-bump!*

EDIT: I think we just had a time slip. Some posts have disappeared. Database restore?
I think I'd chuck that mouldy Tek in the bin. Not sure I'd even want to try and recover anything from it

More progress. We have a crystal filter that works.
Output, now just the IF...
On to BFO...
Going to see if I can get this receiving stuff off the airwaves today or tomorrow.

After being stymied by the setscrews, I moved to the back of the scope. No joy. At least six rotted screws rusted in place. I will have to drill them out, too. With half a day invested already and no end in sight, well yessir I am starting to question my sanity. In case you all weren't already doing so...

These little guys are your friend. Best $10 you'll ever spend. Make sure you get a set that goes down to at least #0, though. IRWIN makes a better set just for screw heads that doesn't require drilling, but cost ~$25: https://smile.amazon.com/dp/B0002NYBHI
Of course, IRWIN also makes a similar set of stud/bolt-head extractors. Yes, they're more expensive at ~$35. And yes, damn those monsters at IRWIN, they WORK.
It all depends on how much you value your time and assache over money.

I don't mind assache (which should be evident if you've looked at any of the photos I have posted over the last couple of days) but I do hate wasting time...
I was actually on my way to the hardware store to get a decent set o these. ez-outs, as we used to call them. If I need to order them online, I am going to put the 466 aside and try to put a couple more hours into the furnace room/inventory/crating/organization project...
Yeah, I have EZ-outs too. And pipe extractors. And Zip-outs. Noticing a pattern here? I've collected a small army of this kind of tool; they're pretty much indispensable for mechanicking.
These are better, at least with small fasteners; this breed of tools have undergone quite a transformation in the last decade or so, with the ready availability of inexpensive specialty alloys.

your solution for wiring the old oval hp power sockets surely qualifies you for the "crown of bodge".
I'll wear it with all the dignity I can muster.

The HP 53816B Universal Counter that I ordered came in today. It is in extremely fine condition and came with the original printed manual stil in the original plastic shrink wrap. The manual and instrument are pristine. They packed it about as good as it is possible to pack it for shipping. I don't even think a train wreck would have fazed it.
Very nice. I wouldn't even know where to look for them ...
One in France if the seller will take an offer eBay auction: #352652284969
Thanks. A bit expensive with shipping (which also seems dangerous to them, according to Kosmic), and no payment option that fits.
I will specifically search for them from now on, every once in a while.

Damn, down the tool rabbit hole I go. My local hardware store, which is only called that because there's a sign that says Hardware Store out front, has to order whatever I want anyway and it will take a week. So, off to Amazon, and soon I have a cart containing several species of extraction device and one or two other things I have been meaning to order.
I step away from the buy-it-now button and decide it is time to walk the dog. None of it will get here before Tuesday or Wednesday anyway, so the 466 is going to get put away for a couple of days no matter what.
Could've been worse!Even I wouldn't do a bodge like that. I do have some standards.
