This channel is pure gold to learn basic electronics but without the boring parts, with well prepared episodes and with a logical structure! I can't thank you enough for this!

[daverush]

All I can say is that these are the best electronic repair videos on the internet. Not kidding. You are doing a great job. I plan to watch all of them. Thanks for putting them out there.

[jonathansnow]

I enjoy how you get right to the info without doing a whole intro with a logo and annoying music. Just a simple logo dancing there as you start. Thank you for that.

[MrTaylorJefferys]

I'm not even going to let the video finish I want to say I've been trying to figure out transition for 10 years this is the first time that I've understood it 100% and it makes perfectly good sense to me now thank you very much

[MattyEngland]

Watched lots of videos about transistors, yours is by far the best. Thank you.

[ianhewitt]

Really good explanation and presented very well. Not patronising, but clearly a man who knows his stuff and can convey it to others. Just wish I had come across this sooner. So thanks for taking the time to record this and get it out there. Very much appreciated.

[toneelectronix]

Germanium transistors are still used for guitar fuzz boxes to this day. Usually to get the "vintage tone" some guitarists search for. One thing I noticed also, with the cheap transistor tester, it read 1.1v for voltage drop on the darlington. That could indicate it is reading 2x the voltage drop of each junction inside.
Love your videos! Keep them coming! Thank you so much!!

[jimbossemi-customs]

Best electronics site I've found, you explain everything very clear to a person who knows just enough to be dangerous. I've learned a lot from you, thank you.

[steveo]

These videos are amazing. Thanks for taking the time. Wish I had these at college

[michelbadawi]

I wanted to take a moment to express my sincere gratitude for the incredible seminar you conducted on semiconductors, transistors, and MOSFETs. Your ability to break down complex concepts in a clear and concise manner within just one hour was truly impressive. Your passion for the subject shone through, making the intricacies of these components comprehensible and engaging. As someone who has struggled to grasp these concepts in the past, I can confidently say that your session has provided me with a newfound understanding that I failed to achieve during my months in university.

[Fanan]

Excelent video, clear and simple concepts. Learning a lot with your lessons. Thank you for your time.

[ClausenLT]

This is really cool. I have a pretty nice Parasound 6 channel amp. I'm pretty good at fixing very basic stuff, but the issue I am having with this amp, I didn't think was something I would be able to tackle myself. But the cool part is I have sat here, without really getting distracted, and watch 50 minutes so far, and I'm not really getting lost or confused. I don't understand everything, but I understand enough so I think i can continue to learn and maybe fix the issue I am having with this amp, which is a protection overload issue on one channel. I will keep watching and learning. Thanks for this awesome channel!

[Ori-Retro-Gamer]

Really enjoying your instruction, i wish i has youtube and tuition like this back in the 80's when i was studying GCSE electonics.. the kids don't know how lucky they are. Many thanks

[Daffydubs]

Man you should put these on Spotify! I would listen to these at work everyday.

[WindellChapman-kfwr]

Played w/ transistors, mostly as switching devices, since 1966. Semi retired security sys troubleshooter ... Thanks ever so much for such great memory prodding info ....This is your forte !!!

[Thetraful]

Much thanks and greetings from germany. The way you explain those topics is just amazing and very understandable. Please keep going with the video series as this is a great value for young upcoming technicians and engineers. Thank you so much! 🇩🇪👍🏻

[briankotze]

Agree with previous comments. Firts time transisors makes sense to me. Appreciate the time and effort.

[highflyingfalcon]

God bless you for the precious knowledge, that you give as for free!

[christopherholmqvist]

I'm blown away about how good these lections are. Following you with high interest.

[Curranproducer]

in the 1st 8 minutes of this video I learned MORE about transistors than I have in 5 years of trying to read about them and comprehend them! thank you!
