    Great!
    Having worked in three branches of electronics for 38 years and now aged 74 years, I still have a lot to learn. In particular, I have a couple of klystrons, apparently unused, but they are the sort without a built-in resonant cavity. It would be good to learn how to put this together even though I could likely get a few mW of microwave RF using a Gunn diode.

    The 3rd item is also known as a 'varicap' diode. The number of switch positions on the switch was easy by looking at the notch-outs for the toggle lever. I'd call it a SPTT center off SW.
    I got everything correct at a glance except the solid-state tube substitute device. I have a couple of bags of Teledyne hermetically sealed relays in that package that led to my confusion.
    Back in 2012 or so I was 'the old guy in the backroom' who handled incoming surplus at a surplus electronics store who identified and priced all of the incoming surplus. But I really blew away the young guys working there when I identified a 19" rack equipment piece for them, telling them that it was the in-house built control unit for a 4 CRT vacuum pump-down cart used in the early 1970's in building C at HP in Colorado Springs as part of a 4 cart array, used to evacuate and seal oscilloscopes and HP CRT monitors, and I then described the abbreviations on the switch positions for controlling the mechanical, diffusion, cryogenic pumps, and oven controls used in the process. When a new guy at the store said, "You can't possibly know all that," I replied, "I could if I were the guy who was operating this pump-down-cart control unit at HP in Colorado Springs back in 1972."

The days of the CRT are gone and people will not even know that direct write oscilloscopes are even possible soon. These days everything is filtered through digital hardware and software, always with the possibility that some nation state actor has hacked your unit and you are not seeing what is really there like the Stuxnet saga.

    Really like your videos! I've been in the electronics industry for about 50 years and recently retired. I started out building circuits in Popular Electronics, then went to Heathkit, then original designs. Started working after school at a TV/Radio shop and doing automotive electrical stuff. Later came two way radio, random electronics repair, collecting (and repairing) old test equipment and radios. Eventual ended up working on broadcast transmitters, worked for calibration labs on and off, did pretty much everything both tube and solid state, and things to numerous to list. And it's all been fun. Even used to have a garage shop about as packed as yours... Then I got a divorce. T.T Had to get rid of 99% of everything after that - but there is a lot of fun small solid state test equipment and ham radio stuff too :-)

      #4 could've been a ceramic isolator/standoff or (gas discharge) surge protection, althou those have much bigger screws usually.
      #6 could also be a weirdish inductor, a bit similar to resistors that have coil wound around them. My car has one such green monster in radiator fan control, bit smaller in size. There are much bigger ones out there.

    When I saw that large capacitor it triggered a memory. I was around 10 years old I'm 74 now and my Father was part time engineering the local radio station. The transmitter was off the air and the problem was one of those large capacitors had exploded. The station was AM and directional at night. Dad and I walked all the way out to one of the towers and borrowed a large Sangamo capacitor from the tuning unit. He installed this capacitor in the transmitter, it was a little off value and voltage rating but it worked fine on low power until a replacement came. I've made my living as an electronics technician starting out repairing television sets and retiring from the Missouri Highway Patrol as a district engineer for the communications division. Thanks for the trip down memory lane.

    Well this was a fun diversion! I'd love to see this become a series.
    1) Guessed correctly.
    2) I was almost half right. I thought it might be a transformer of some kind.
    3) I guessed it might be a diode... I guess that was technically correct, but too general to get the point.
    4) I did not guess correctly. I thought it might be a massive HRC fuse.
    5) Got it! I've never seen one like that though. I wonder what it was used for?
    6) Got it too!
    7) Nope, I thought it might be an IC or a relay.
    8) Got it!

The mica capacitor I guessed a vacuum capacitor or high voltage surge arrestor. MY guess on the large resistor was a high-voltage fuse. My guess on Teledyne was a relay. The ferrite rod with copper winding, I guessed a common mode choke probably for emissions.

    I'm only 26 and I was quite surprised that I knew what I did with my limited skillset.
    1: The Relay I thought was an early transistor
    2: I was right with inductor but also thought it looked similar to a multi-tap transformer.
    3: Didn't know it was a veractor diode but instantly thought it looked like a transistor with a broken leg (thought it was going to be a trick question) as I've never heard of them before.
    4: Had no clue that was a capacitor as I didn't see where the wires connected to 😅
    5: Got the 4 position switch instantly, noticed the grooves in each corner and the 4 terminals on the back
    6: Saw the windings underneath the green coating so gathered that was a huge resistor.
    7: Had no clue that was a modern tube replacement as I've never worked on old tube equipment, I just like seeing people restore things I'd never have a hope of fixing with my current skills with a soldering iron. That maze of things connected without PCBs is quite confusing unless I looked at it in person and had days or weeks to reverse-engineer it or by replacing things component by component until it worked again.
    8: Gathered that was a choke as it looks similar to a toroidal choke with the amount of separate connections to it.
    9: Got tricked by the last two, thought one was a resistor and the other was a capacitor, now I know green usually signifies an inductor. The earlier image with all those capacitors helped me to some extent but also confused me as seeing colour bands on capacitors aren't something I'm used to except on the "domino capacitors"

    No5 4-way switch. I recognised its function immediately as it is similar in function to the 6- way 'Freeway' toggle-switch that is a replacement for the 'Switchcraft' 3-way toggles fitted to Les Paul style guitars. I have one about to be fitted to one of my guitars.
    No6 Big green 'dropper' resistor - I've got a few of these big ceramic jobs in my spares.
    No7 'Tubester' - I knew its function (replacement for thermionic valves...), just never heard it called that before.
    No8 Inductor - heavy duty - 'for the use of' - In this case, I knew what it was, but not what its function might be.
    No9 Figured the wee glass bead was a zener diode... Had no clue what the larger 'resistor lookalike' (inductor) was though.

    Interesting quiz. I only really missed the first one - the 2-legged TO-92 could be one of a few things, really... I have seen Diacs, thermistors in the same package. The mini tube got me. I thought it was like a hermetically sealed transformer. Wasn't aware there were styles other than the Nuvistor. I have seen mini axial caps like that in some VHF receivers, and they were all low picofarad values as well.

    MICA CAPACITOR TRIVIA. The Bellingham Radio/Electricity museum melted their Sanyo mica capacitors (by running their large Tesla coil for way too long. Guess it needed cooling fans.) Molten sulfur ran out! So, at least with older ones, the whole thing is embedded in that 1700s-era polymer insulator called melted sulfur. I'd seen sulfur insulators in ancient physics devices and pre-1900 antiques, but apparently it's still being used. Good idea: ...unlike epoxy and tar, when greatly overheated it won't turn into charcoal and short everything out.

      I remember reading the longest running battery that drives an electrostatic bell has been going for about 100 years and is insulated with sulfur.
      On opening big HV mica capacitors like that I have found them potted with a very stinky waxy product. The sheets of tin and mica are very pretty.

    The vacuum relay is reminiscent of the devices used in the BTtF flux capacitor.
    That filament choke could be repurposed as a balun.
    The stubby resistor lookalike capacitor was new to me. I have probably seen them before without realising they are not resistors.
    Lovely selection, I recon you have enough to do a few more like this. Add some traveling wave tubes triggered spark gaps for variety.

    abundant construction with absolutely no attempts made to cheapen it's construction, at a guess it weighed about 30kg+ and was a work of art. Happy days.

    Oh BTW... without your channel I would probably only had the numbers of switching positions right... I want these in a smaller format for eurorack modules 😊

    4) a ceramic fuse? nope
    5) four position switch... cool!
    6) huge resistor like in a 100 year old fire alarm control panel, yup! too many of these still protect buildings...
    7) an early IC, or a tiny tube or relay... sort of!
    8) braking resistor was all I could think of, but knew it was wrong from the ferrite

    I found a varactor diode in a sony AV remote, that I repaired, which had it's ground connection pad ripped after the remote was stepped on. Didn't know what it was but assumed it was some type of transistor based on the shape. Reconnecting the ground with a bodge wire fixed the remote.

    Not all of us would know all the devices used in commercial electronics equipment and high powered transmitters, but the smaller components you showed near the end of the video I knew one was a choke coil and the other was a small value capacitor. I have a small collection of those kind of choke coils.

    The first one is kind of famous, as in from the movie "Back to the future", with three of them in the 'Flux Capacitor'.
    The third I guessed as a diac, often used as a trigger for Triacs in light dimmers etc, more used to seeing varactor diodes in axial packages.
