Thank you Richard for the effort you put into your videos, I really enjoy them. If you are looking for content to make videos, I would like to see more on digital electronics the actual ic components themselves, explaining how they work and how to test them using an oscilloscope for example: multiplexes, multivibrator's DAC,ADC, flip-flops,shift registers,latches,timers,counters etc. I think learning digital electronics is becoming more and more important as we move further into digital electronics. Even if you don't know all these things the best way to learn is to teach it. And I guess you've learnt so much yourself by teaching us. Thanks once again Richard.
Thanks for handing down your experiences Richard. Your videos are organized, frank, and honest. I frequently have your repair on my workshop playlist to keep me company in the lab. I might even pick up your English accent.
Another great video Richard. I got a lot out of this. I am sure it's going to help with refining my methods. Thanks a lot and have a great holiday season. I gather Santa won't see much snow in your neck of the woods!
Apparently we could have snow here up in the mountains this weekend! This only happens once every three years or so and only lasts for one day. Here near the coast it is forecast 23C daytime/15C nighttime dry and sunny every day over the whole Xmas and new year period. Actually if you are interested we do have Christmas lights in our town. This is how they do Christmas here (and me in my alter ego presenting a video we made of it) ua-cam.com/video/0oLNxATy9nM/v-deo.html, This is free to visit and park your car, then from 21st Dec - 4th Jan we have Expo Navidad at the same location. This is also free to visit and we have kids activities, live bands and DJs plus an outdoor ice skating rink until midnight every day apart from Fridays and Saturdays when the food trucks and beer trucks plus the DJs go on until 1am. Knowing the Canarios this is going to be very busy and very loud! They will probably ice skate in bikinis.
Thanks for all your videos. I always enjoy watching you patiently "poke" around dead amps. I have a Bose audio system and a Sony Blu-ray player that were damaged by lightning hitting the house. I figured they were beyond amateur repair, but I'm going to give it a try and do my own "poking" around to see if I can bring them back to life.
In years of working on electronics, I've never encountered so many cement power resistors installed "upside down" as in your videos. I've virtually always seen them installed with the potted/filled side down, writing on the side. In your videos, I keep seeing them installed with the cream filling side up. At first I thought it might be heat dissipation, but even the ones I've seen that get really hot like in old CRTs, are installed with the cavity facing down, but on thick leads holding it an inch off the board. Can you explain the benefits of the upside down installation? It would be awesome if you could post a short with two identical ones in series, one upside down and one regular, filmed on the thermal camera.
In truth I actually never thought about it but I would suspect that if the cement side is upwards, and seeing as it is a thinner layer to the air and heat rises then maybe this 'upside down' method is actually the right way?
Hi Richard. I would say resistors ALMOST always fail high/open. I have come across a couple over the years that have gone low in value, both carbon comp types, and I have heard of certain types of wire wound ones going “ shorted turn”. Resistors going low common? No. Does it happen? Yes, but granted not very often.

Yes this is most definitely a two way learning process 😀

Heya, yes learned some more thanks

Richard explain the safety Caps X2 and X1Y2 or what the markings mean.
