I liked the dio-citor, myself...

Skipped your morning coffee? That's the standard symbol for a Varicap.

After yesterdays Blood Bath of injuries I opted for some 'safe' woodworking by Laser. Because Lasers are safer
Couple of woodworking tools, marking gauge, marking knife and a center finder. Trial fitted and glue up tomorrow time permitting. Marking knife blade is subbed by a ply one until I brave the hacksaw and grinder.
Fusion 360 for the modelling bit.
Hey @Brumby want to raise the blood pressure of SHMBO 'some more' Needs some love but if it was closer I would find a place for it in the toy collection eBay auction: #193188410543
Hardly. We are still visitors... tourists. The trailer is in storage stateside until all our paperwork is complete. We arrived here with what we could pack in the back of a Rav4 (plus 3 storage bins on a trailer-hitch fanny-pack).
So much cash outlay just getting here, then all the stuff you need to buy to "startup" a new household... Dishes, cutlery, coffeepot/nukebox/toaster, etc... the first pantry & fridge-full of food... Shit, we spent $350 yesterday to get Parkas & heavy pants for the boi & grrl. At Costco we spent that much just on 2 kids, FFS!
So yeah... there's a reason I'm shopping nonessential shit like this from the Thrift.
I still got 4 good satellite speakers out of the thing... plus I can always seal up the sub & make it passive; run it from another amp. Maybe shell out the CAD$10 for a TPA3116D2-based 2.1 amp board upgrade. Woohoo!!!

Dammit... now I'm thinking about how I need my printer to make the backplate...
Although not strictly test equipment - it certainly is a Boat Anchor. On the weekend it was our state's biggest buy and sell - lots (well 3)of Yaesu FRG 7s - a lovely receiver.
But a FT101B for AUD 50 with all bits minus the 'finals' was too good to pass by. Cosmetically pretty good, no final tubes but I happened to have a spare pair for my working FT 101E, The dial has the sticking issue and some idiot has burnt out one of the blades in the power connector - so a bit of sleuthing will be required - a bit of fun. My fingers remain attached at present!
...was going for this. maybe a little too old and too obscure?
I chose to stay out of yesterday's discussion of scars and stitches because I don't want to rehash in my mind all the nasty injuries I had as a kid with glass, rocks, and deli meat slicers.
The stories I could tell and the scars to prove it.
A few years ago I was given a THX certified sound system, I was told that it was a 5.1 system and I was expecting something small like you see in computer shops with the flat panel type of side speakers, instead I was confronted with this beast of a system that weighs over 40lb .
Getting it home and connecting it to my computer took my breathe away with its huge powerfull deep bass and sheer volume, the thing is capable of delivering continously 200W of power, not peak power but 24/7 RMS watts that shakes the doors and windows if you wind the volume up. Watch a movie and have the sound delivered via this on the PC is awesome, it beats the pants of my system for the TV and to think I got it free, even today I pinch myself, never heard anything to match it either, watching movies on it, you get that real deep rumble that makes your stomach tremble just as you get in the cinema.
You moved a metal shark but not your toaster and plates?
@bd139, thjat case you made sure looks good and quite sexy in blue to boot
An 8810A ongoing update. It took just under 2 hours to reach yesterday's cal point. Not unreasonable but the similar 8800A's reach that point in under .5 hours. But what IS encouraging is that it's been powered up for 5 hours now and once it reached that cal point it has NOT drifted any lower.
I think I know why the change from last week's miserable total drift from 9.9974V down to 9.9964V but I'll wait and see once it has close to 10 hours on it.

My Solartron 7081 has a procedure for when it has been in storage for a while. You wrap it in a blanket, turn it on, and let it cook at 40C for a day. Apparently that evaporates any volatiles on the PCBs.
Maybe something similar is happening here.
Hmmmmm... initial inspection shows no evidence of fire or magic smoke, and the rails are steady on at +/- 25.5V from a good old-fashioned linear power supply buried in the sub enclosure. After an hour powered up, all finals feel slightly warm but none warmer than the others.
Based on specs, I expect this should deliver right around 25W continuous per TDA7296 in AB operation, and this thing has 8 of the little bastards with two in BTL mode for the sub at probably 75W continuous or so. Fukkin-a-diddy! That's $50 worth just in the finals!!!
Now I need to figure out how to do turn-on/un-mute to inject signal & see if they're all healthy... I have an eval circuit in the datasheet, so should be able.

... our state's biggest buy and sell ...
Is that Aussie colloquial for what's called a "bring and buy sale" here in Blighty? Something along the lines of a jumble sale but where the goods to be sold (usually for some good cause) are brought along and donated on the day by the people who have also come to buy things.
This NanoVNA thing is the nuts. Thanks again xrunner. And also TEA FTW.
