Think it’s polyurethane tubing and the problem is called blooming. Early PU wasn’t that stable. Capacitors might be fine even if they are pretty fugly. Worth testing some if you have an ESR meter.
That sprague black beauty to the right worries me more
I don't care. They look like the Heebie Jeebies and they are getting replaced.

Impressive collection
Accidentally bought a second HP 2802A thermometer a few weeks ago from CDL for £20 + p&p, bit surprized no-one else bid, maybe the lack of probe with it put others off.

They both probably need a cal check with an ice/water bath at some point, as per the the calibration procedure. Despite the extra resolution mode the accuracy is apparently only +/- 0.5°C.

All I need is a 10 day week and 30 hour day
BritishScottish engineering invented the modern world. Not with silly little 2.0 litre V10s though.
TFTFY. James Clark Maxwell, Alexander Graham Bell, Logie Baird, James Watt, the list goes on. I never cease to wonder at the way us Brits always say it's British if came from Scotland and is something to be proud of and it only becomes Scottish if it's dispreputable (Buckfast drinkers), yuckky (haggis*), or life threatening (Scottish Country Dancing).
*Personally I like haggis.

Are your coffee beans really that bad ?

Me too, but I like black pudding & pierogies, too!
There are things I draw the line at, though.
Rollmops!, Eels!, --------- both blechh!
The Poms tried to push "North Britain" as an alternate name for Scotland, but it "went over like a wrought iron hanglider!"
It seems that not just Scots, but Commonwealth countries become "British" when there is something really nasty going for Brits!
Most of the rest of the time, we are just "furriners"!

Teds? How's that going to help? I mean, it'll probably be a fine party, but ...

I've seen them in HP stuff too and haven't given any thought to what it was, just got on with cleaning them & reinstalling them if they tested OK.

Teds? How's that going to help? I mean, it'll probably be a fine party, but ...Us male section of the human species do seem to have a minor glitch in our programming, in that we find dumb looking women attractive.
A nice looking (often blonde) "mouth breather" appears, & it's "all systems go!"
It seems that stuffed bears have the same quirk!
I have its brother, the UBC125XLT Airband and general scanner, I'm very please with it too, brilliant little scanner, its performance belies its size.
Airband was one of the bits I really wanted the little Baofeng UV 5R does the rest fairly well. Emergency and Fire is the other bit I wanted so some of the trunking features might be handy as they have all moved up from their older HF range gear.

No doubt, but GRP would have been as good, since for ultimate strength, CF/R needs curing in a nitrogen passivated autoclave.
Do you mean 3D printed glass filled plastic in the context of Zucca's questions about 3DP? I don't think that's an option. Or do you mean glass fibre in place of carbon fibre?
If the latter, CF, even when it hasn't had the aerospace treatment, is still stiffer and stronger than glass fibre for an equivalent sized gob of it (and let's face it, this is a gob - I didn't vac bag it, I didn't degas my mixed resin or even reach for a consolidating roller, I used a lolly stick), and, and this is the clincher for me, I don't end up with little itchy bits of glass fibre under my skin like I have done every time in my life I have used it no matter how hard I work to avoid it. The box with the resin and other bits has three packets of reinforcements in it: one's got glassfibre in, one's got CF in, and one's got some polyaramid cloth in. What material gets picked as reinforcement depends on what I'm doing.
