Re: Marianne Faithfull dies at 78
Sad. Splendid album; "Broken English". I was working in the lab one day with one of her later albums playing and the (bad-tempered and strait-laced) Dean strolled in just as she warbled about having her first child at fifteen. He was not a happy bunny. Especially as he couldn't do anything about it.

Re: Interesting (non musical) YouTube videos.
Yes, interesting, but very repetitive. Could easily have been edited down to one third of its length without losing any content. And I could have done without the relentless HPAK (Hewlett-Packard, Agilent, Keysight) hype. But they did lend him the use of their expensive kit (presumably without fee ...

I find it amusing that the company Nordost says it specialises in audiophile and medical equipment, thus fully qualifying for inclusion in this thread.

Re: Nothing In Particular
The bottom line is that analogue POTS is a dead service and will go in the near future as the infrastructure is too old, knackered and expensive to maintain.
Indeed. And part of the new cost has been shifted to the customer by requiring that BT/EE's terminal equipment has been moved to the ...

Re: iRIAA filter PCBs
I would say it depends if you plan any distortion measurements. But you don't need the inverse RIAA for that just set to constant output from the stage.
Actually, you do. One of the specifications that is often missing from capacitor data sheets is how capacitance varies with frequency. C0G/NP0 ...

Re: Slow Mo MoFo
I remember doing my Physics "A" level examination. You could tell which candidates were on a particular question because their hand would come up with fingers and thumb extended and they'd be peering at it. Of course, you needed to know which hand was appropriate. That was solved for me rather later ...

Re: Slow Mo MoFo
On your previous MoFo, you had two inductors with their coil axes aligned - you won't want to do that on this one. Even better, make sure their coil axes don't point at anything sensitive.

Re: HT and filament heating from the same transformer
I guess the question is - is this theoretical coupling of rectification noise into the heater winding really that much of an issue in reality? Context - we're talking all-AC heating.
YES. But it's not just HT rectification interference, it's any common-mode interference on the mains, and there's ...

Re: PTFE hookup wire - help!
Amateur radio rallies are your friend. https://rsgb.org/main/news/rallies/ I bought a carrier bag full of PTFE-covered wire on reels for £10. Beware that the stuff is horrible to strip. And you want solid core for a tight heater twist. Also, https://www.bvws.org.uk/ but you need to become a member ...

Even though it was like silent hill in the fog, 40 yard visibility. Spotting other walkers slowly shambling through the fog in the distance was a bit creepy, but thoroughly enjoyed that.

Re: Seasons Greetings 2024
Didn't spot that one, either. Perhaps because I never watched the programme. Some years ago there was a Radio Times Wallace & Gromit poster "Radioactive Times". I stuck it up at work over my bench; should have brought it home.
