You should be proud man, it's astonishing how many well informed suggestions your audience has for this technical stuff. and a good few of us wouldn't have a clue if it weren't for your vids!
Really appreciate this comment because I had no clue about these things when I started to watch your channel. Now I was following along this video and giving similar suggestions.
Looking forward to the mains power vid, I always wondered if any of the comp guys ever bypassed the power supply section and sent power straight to the rails
@@steve390gold That's awesome, I would love to see someone hook one of those up to a hybrid and use the factory high voltage system to run the amp. Hybrid Tahoe would be perfect
Thank you so much! It was so much fun seeing other people ideas and thought processes to get it up and working. And thanks to all that I now know pretty well, how this amp operates and how to fix it if I come across one of them.
CHECK THE SWITCHING OUTPUT FETS WITH NO SOURCE FETS, HAHAHAHA THE bakcground piano music was the funniest moment in your channel, i laUghed a lot, thanks!!
It was a great stream. It got me thinking and did make feel I was under a test, I fucking love tests! Do again man. :D I still got my go from my pass :D :D :D lol That must of been a tought edit. Also good that you propper mullered the board first so ended up a top to bottom scenario fix. I usually dismiss optos at fault but they are a transistor at the end of the day.
Interesting!! Ive got a type 4 problem that i cant seem to solve. The pwm switching is being generated however the voltage (amplitude) varies all over the place. Sometimes it produces a nice 4 to 5 amplitude wave then all of a sudden it drops to 1.5v which of course wont drive the the irf640N's. Also the drive signal seems to not be grounded well and is bouncing all over the place vertically on the scope screen.
Does this happen equally on both sides of drive? Check the auxiliary transformer wind, the little thin one that creates the vcc source, maybe change the little rectifier diodes on the board that are before the regulators.
@@barevids im not at home right now but if memory serves me the pwm wave bounces around on both sides (post octocouplers) and to a much lesser degree out of the LM6172 before the 74hc00d. The amplitude voltage also varies out of them too but again to a lesser degree. Thanks for the reply, I will check both when i get back home. :)
I have a ,, alpine , mrp m1000 amplifier , it turns on but doesn't want too make sound coming out,, it tries too , it doesn,t kick off, it just the out put sound is on off on off , there's no smell, an nothing is burnt or broken
barevids doyou buy any chance have a list of the mosy common mosfets and ic used on all amplifiers so i can buy them so my repair process can be as smooth as yours?

I remember this stream. It was awesome! Like this condensed presentation of it. Love all the little fun edits... "we removed the devil!" 🤣

This is exactly how the taramps high voltage amps operate. Feed em 200+ vdc

This was so good... but you scared the heck out of me with the 666 part lol
23:13 omg 😲Don't do that bro! hahaha you got me there! 😉
That was a blast. You should do more of these.
I love the fact you left in the bit about straightupkickyaindanutz.
Great job everyone, you guys rock !
This is such a cool idea. But it gave me a huge fright when you got sparks lol
Great live stream!! Would love to see more if these!
I love your channel, so bad I can't always stay so late night wathing you blow amps! 😁
Dude you got me good with the explosion hahaha
if all else fails, apply 400VAC 😂
or send one to PhotonicInduction to use on the HV capacitor banks
Love all your work
Great video! Great Idea for a stream!
great content! keep going, I love it
That was a great idea and great video man. Good job

Good learning in that stream.. loved it.

Enjoyed participating in this.
Was fun and interesting Live stream😊👍
What oscilloscope do you use?
I have a ,, alpine , mrp m1000 amplifier , it turns on but doesn't want too make sound coming out,, it tries too , it doesn,t kick off, it just the out put sound is on off on off , there's no smell, an nothing is burnt or broken
i have a problem with the player the alpine 178bt goes off and goes on doing it all the time...... on off on off....
Hi just curious.. do you work from home or do u have a dedicated shop?
Home, it's not worth the expense to have a shop. Wouldn't improve my work in any way.
I have a kenwood kac-9103D powers on but no sound
Woaahhh EXO was here??!!!! thats amazing
Please do another one soon.
modifying an AMP to accept 220Vac instead of 12V dc sounds... exiting, better be a live video, i want to see some magic smoke
I think there will definitely be some magic smoke extracted 😂
I wish I was online at the time.
Me too....

BAREVIDS CAN YOU PLEASE MAKE A 30+ HOUR COURSE ON AMP REPAIR ON UDEMY PLZZZ!!!
