Yes, when the switch is turned back to the center position, it connects the terminals together through a 3.3k resistor. It is putting less than 30V on the cap, so it is not too scary.

to get the glass tube out you have to unlock it like you did in the video with the back button at the back, then when black backpiece is loose, you have to pull the glass tube as far as you can toward the backpiece, and lift it up from the other side (the front). It goes pretty easy once you know it. (i had trouble at first with it too) - Make sure once you pull out the glass tube that the metal cross piece inside the glass tube might want to jump away by the tension of the spring. So make sure you are doing it somewhere where it cant jump at weird places where you cant find the thing anymore. Another hint, if something you desoldering contains a big blob of solder the desolder gun can get stuck (not sure if flux levels play a role, or very old solder, but it doesnt really show it because the glass chamber looks pretty empty, but a lot of solder can be stuck inside the metal tube piece before it enters the glass chamber. You will hear when this happens, because then the suction sound will sound weird, like tiny farts. If the sound of the suction ever gets weird to you, and you see the glass chamber isnt full at all. Then use the metal rods. Or you risk that the solder at the front metal tube still sticking will come out by gravity all at once once you use the gun (at a higher temperature). I had luck back then my Atari Lynx lived that assault where a big blob of solder came out of the desolder gun and dropped at the motherboard (thanks god at a place there wasnt anything important). - The only thing that warns you about that is the suction sound before that the desolder gun is making (not the unit).

Maybe the (proper/non-conductive) adhesive that is used to tack down big capacitors. If your going to use electrical tape, use the type that welds/melts to itself. The adhesive type will unravel and tell you later that it did. Another tip... I don't use hot glue, because of all of its known disadvantages. I use "Shoe Goo."

Hi, i just came across this video because it was recommended to me. Since I've been working on a project with isolation transformer and autotransformer, dim bulb current limiter and DIY electronic fuse all together in one housing for some time, I've also done all the necessary research. At 8:09 you say to remove the ground pin from the primary side, but this is not recommended. Because if the live wire comes loose internally, and touches the metal chassis, your GFCI won't trip and you will get a zap when you touch the chassis of the isolation transformer. If you absolutely do not want to use the ground, disconnect it from the secondary side, or use an output socket with no ground pin connected. I've seen countless videos about isolation transformers in the last 2 years, but it's rarely if ever mentioned that an isolation transformer also has a ghost voltage between the output and protective ground. Depending on the construction of the transformer, this ghost voltage can rise to more than 50% of the mains voltage. This ghost voltage has a low current in the µA range, but can still light a small neon lamp or LED, so it should not be ignored. Which is also rarely if ever mentioned,is that a GFCI behind an isolation transformer will not work without making the necessary adjustments. For a GFCI to work, there must be a leakage path for the current, since the output of an isolation transformer has no path to ground, a GFCI will not trip. Since the neutral and ground are connected in the breaker panel (in US and UK) or both are almost at the same potential (Europe), you can connect 1 wire from the secondary (before the GFCI) to the ground pin of the output outlet. Then if the live wire from the DUT (Device Under Test) touches the metal chassis, the GFCI behind the isolation transformer will trip. To lower the ghost voltage, i plan to connect the connectionpoint of the live wire and ground pin of the output outlet to protective ground through a 2Mohm resistor. This drops the ghost voltage considerably (in my case to max 30V). Because the secondary side of the isolation transformer is now grounded through this 2Mohm resistor, a current can flow to the protective ground if something goes wrong, but this will be only 120µA with 240V, and only 60µA with 120V. 120µA is barely noticeable, and certainly won't damage a scope probe and scope if the probe's ground clip is connected to the secondary's live wire. This 2Mohm resistor needs to be 2 or 3Watt type, because the smaller like 1/4 Watt type are not rated for 240V. Grtz from Belgium

Thanks for video. Is transformer of this amp can be adopted for 220v AC? Maybe there is two 110 two windings, so I can break them for 220 AC current? Or there's not, so this amp I can use only with variac? The manual of amp says, it has ~200 watts of power for 4ohms. Is that means, I can get 200watt on each 4 ohm speakers. or just 100watts for each one?
@srtamplification Жыл бұрын
120V only on the transformer on this one. They may have made some for 220V though, I don't know. It is 200 Watts into a 4 ohm load. That could be 2 100W 8 ohm speakers in parallel. Or many different combinations. It will work with other impedances, it just won't deliver the same power.

Lucy may make some more appearances in the future.
@@srtamplification It wouldn't be youtube without cats in the videos. Happy new year.
WOW, YOU HAVE NO IDEA WHAT YOU ARE DOING DO YOU?
Good video, but I would suggest that nearly a minute of opening "splash" is way too much.
Maybe you can start your own channel.
@thatampguy , uh, I have had my own channel as long as KZread has existed. It is stupid to deflect constructive criticism by throwing it back in the critic's face.
Thanks for video. Is transformer of this amp can be adopted for 220v AC? Maybe there is two 110 two windings, so I can break them for 220 AC current? Or there's not, so this amp I can use only with variac? The manual of amp says, it has ~200 watts of power for 4ohms. Is that means, I can get 200watt on each 4 ohm speakers. or just 100watts for each one?
120V only on the transformer on this one. They may have made some for 220V though, I don't know. It is 200 Watts into a 4 ohm load. That could be 2 100W 8 ohm speakers in parallel. Or many different combinations. It will work with other impedances, it just won't deliver the same power.
@@srtamplification Thanks for answer. Try to terdown my one, and figure it out. Thanks again.
That sounds sweet! I just got one of these at an antique sale for $60cad, but of course it needed a bit of work. It needed a power cable, and had a loose tube. Got it going today, but ill give it a good test tomorrow.
LOLOL I know you mentioned the garage before but I didn't catch it, all this time I thought you was in basement
Exciting stuff. Keep us posted.
..sounds really good. ..and the amp too. ..real nice.

Thank you for sharing this valuable information! Parasitic drain is the plague of modern autos with electronic saturation. I appreciate your time
Good demonstration, enjoyed your time. Thanks for the look.
That Sharpie is a Bluntie! :-)
I've used one of those for 40+ Years the best tool for fast trouble shooting once you understand the different signatures of components and I've placed side by side working and nonworking circuit boards and found the defective component 🤔 hang in there you'll get it LOL 👍 surely your joking
That's a good scope. Back around 77/78 I carried that in the field and used for alignments and calibration on the controls of Induction furnaces . Thanks for the look, enjoying this series.
Looks good so far. I'm anxious to see if it performs better after the recap. Thanks for watching.
Thanks for sharing. Looking forward to Pt 2.
