WD is a poor release agent.
According to the internet.
I’ve been trying WD40 side-by-side with Plus Gas for well over a decade now and I can honestly say I can’t tell the difference between them. What I will say, is Plus Gas fucking stinks. If you don’t mind reeking of diesel for hours/days afterwards, then get stuck in with the Plus Gas. If it looks like it’s going to be an easy job, then WD40 all the way.

Tesco House Blend at £3/227g makes a perfectly acceptable filter coffee. I didn't see that coming.
M&S Kenyan Micro Lot Coffee Beans at £5.50/227g make a very good medium/light espresso and acts like a far superior bean in the machine. Grinds more like a freshly roasted bean than one which has been sat in a bag for months. I didn't see that coming either.

Change password if you haven’t already. Just in case your details were farmed from Experian.
More likely your details have been farmed from an easier source, probably an online shop or an old app you used with weak security. Google Password Manager in Chrome and iOS both give you breach notifications in settings. May be worth checking those in case there’s a clue there. Also check your email addresses on haveibeenpwned in case there’s been a recent breach.

Ok, they aren’t KT88s. They’re 6AS7s which are low impedance twin triode power output valves, so two chunky output triodes in each valve. The KT88 is different. KT88 is a very big single beam tetrode (very similar to a pentode). All 8 of your 6AS7s are probably in parallel, so all 16 output triodes are in parallel and that’s probably why there isn’t a giant output transformer on your amplifier like there normally would be.
It’s an interesting valve. 100-200W from a valve amp would normally use 4x KT88s in class AB push-pull, but it would also need an HT voltage near 700V. Yours is just loads of output triodes stacked in parallel and only needs around 250V so it looks like it might not even have a power transformer and just runs directly on rectified mains voltage. I’d love to have a look inside that thing 👍

Blimey! I said KT66s because they’re normally that tapered shape and KT88s are normally more of a Coke can shape (and size). I’d definitely be up for a forum listening party (and put me down for coffee tasting) if you’d be up for hosting one.
Your 9V batteries are probably for a non transformer-based biasing. It’s an old way of doing it but I’m guessing low noise and probably means you don’t need to use diodes or LEDs to get a simpler but more stable bias voltage.

Been working at a heritage railway this week and spotted this albino mushroom / fungus about 1/3 way into one of the tunnels. It’s 100% as white as it looks with grey flecks and it’s growing on ballast covered in coal smoke deposits. It’s pitch black that far into the tunnel and one of the drier bits.
Anyone recognise it? It’s the only colony in the whole tunnel.

Good shout. I also want something I can get four fingers round. The Speed Dial levers are two finger levers and we have to hold onto them for about 30 minutes at a time.
[It’s only proving out some tech on a prototype so it’s only got to work a couple of times. We can put up with some dreadful ergonomics as it’s only being used a couple more times]

Probably ought to ask this in the mechanics section, but what are the longest cable mtb brake levers one can currently buy? Tektro look like they do some fairly long ones.
It’s on a heavy contraption with BB7 mtb calipers re-worked to operate as always on (a sort of dead man’s handle type brake) and Avid Speed Dials to pull them off, but it needs a bit more leverage.

I have the tin on the left. Comes with a dripper spout under the plastic lid. Mine is now over 10 years old and smells the same as the
people who have been using thestuff at work.
