I respect you for keeping that discharging at the anode cap in the video. It gives a real example of it being useful, despite most videos on the internet seemingly not having any discharge. It's important, because that discharging resistor may not work anymore or fast enough!

I’m not sure this monitor has one, I found the CRT charged every time! Or maybe it takes a little while. Thank you!

Thank you very much for THEtechknight's channel recomendation. His videos are very cool, nowdays very difficult to find chanels like his. And of course thanks for video about a CRT, I love CRTs so much 😄

Yes that’s why I accepted it! Finally an LCR meter which works well at small price! Thanks for that!

Great video Tony. Always learning from you. You made may day, cursing about the plane in Italian. I do the same in my original language: much more natural and rewarding.

We (me + couple of friends I suckered into it) just recently took on an Apple IIe PAL project, with original disk drives. It's not working yet, but the mainboard is infested with MT RAMs that get very hot. So no surprises there. We're waiting for parts now. It also has an original monitor. That's the part I dread the most... Good stuff Tony!

Amazing! Take a look at Adrian's test ROM for the Apple 2, it might help. A disk version is also available. For the monitor, those are reliable, just remember they have those RIFAs inside! Good luck!

I had no idea the stand was rare these days. The 2c system I picked up a few years back had one, and I didn’t even think about it as unusual.

I’ve seen some around on sale but I understand they’re not easy to find. My 2C is missing it.

Perfect timing. I just took a IIc and OEM monitor and stand out of storage. It hasn't been turned on in at least 10 years that I know of. This gives me a good overview of what my monitor may look like before I open it for rifa and other cap check. I'll be interested to see what model I have. 😂

Please do let me know, I am curious! I thought those monitors were all Samsung!

You could always send it in to Apple to fix it for free...although if they've seen your Focusrite video, probably not.

I just got something with a monochrome CRT. A Tektronix 2236 oscilloscope. In really good shape for its age. Given to me, I just need to buy a set of probes for it. Everything seems working on it. Has a DMM showed on a vacuum tube display. Thing is awesome, have a lot of reading to do with the documentation that was provided with it.

I just googled it - the DMM display is SO cool! I used to have an old Tek but the CRT was very used, pretty soft. Eventually I found my old Fluke which was amazing - but it needed a desk by itself :)

Videos both in 259 and 359 channels are great and very interesting. And i am watching each of them only minutes after they are released. Personaly i would replace only capacitors that are spoiled. Of course for these years there is plenty of engineering and innovations, but smaller size didn't came from nowhere. It came from thinner aluminium foil - i.e. higher current dencity per mm2 and possible heating if we use them with the same current like the older one. It's similar like the case with the cables in the buildings - 30 years ago it was a must to have 4mm2 for a backbone cable, but now it's OK to be 2.5mm2 and possible small heating is acceptable. Times are different. Also the older caps have a bigger reserve in electrolite probably. That's why they would last 40 years more.

Thank you for following me! If it was my monitor, absolutely, I would only replace bad ones. In this case I had an agreement with the owner to swap them all. I do see your point, I'm hoping new ones are still up to the task, after all this is a very low power monitor. I'm definitely gambling a bit on "let's swap all these caps with new ones" without knowing the specs of the ones I am replacing. Interesting about the change in electricity wiring! Thank you!

Ye, its kinda strange feeling to see smoke coming out of something still running completely fine. Had this "problem" with my laboratory rackmount power-supply. The "Schaffner EMI Filter" exploded and the whole room was full of smoke :D Still the lab-graded power supply still running fine and doing its automated job :D One would think, something went catastrophically wrong.

Something similar happened to me with a Pro sound amplifier. I smelled "burnt electronics", switched it on. Couldn't see anything, turned it back on again, and it was still working. And it worked that way for a long time so... :)🤷♂

Bi-polar caps can have a much longer life than normal Electrolytes. It may not even be necesarry to replace that special cap.
@Tony359_2
Күн бұрын
likely none of those caps needed replacement. It was just a "extending life" exercise. That said, the small bipolar I purchased was only rated 1000 hours (at max temp and voltage so much more under normal use but 1000hrs is the minimum you can get for a capacitor)

I got two of these little apple monitors with their metal stands on eBay back in the late 2010s. The rarest bits which I did not get with either are the guts of the actual shaft mount and the knobs that lock the monitor in place onto the stand. Somehow those pieces got lost in both. Anyone know how I can get replacements?
@Tony359_2

The bottom bit is just a bolt and I'm sure you could adapt something from a HW store. The knob at the sides are just pulling on a standard threaded rod. So that makes "easy" to somehow replace them. The only think is that one of the knob has a notch to prevent the monitor from swivelling too much - so even when you loosen the knobs, the monitor won't fall down, face down, making a big BANG :)
