My right monitor failed in the same way. This video helped me diagnose and fix the problem. Thank you so much!

hey i have a peavey bass amp the fuse blows when i check all the output and driver good ..i check diodes all good and other transistors...power transformer good too.....any idea on how to procedde i did not replace the output sein that it check good i suspect them thou

Brilliant video, great English from you. Thanks so much.

I have the same speakers and one of them turns on but it doesn't sound. What can be the reason and how can I fix it? Does anyone know?

Thanks for the help. How did you take the top cover off (P3T)? After removing the bottom (4) screws, my PeT top cover will not pull off.

A lot of thanks !!! good job!

Thanks, I was having issues finding how to recalibrate this unit after getting it from a surplus sale for a bargain!

Are all battery powered scopes isolated? Are your scope probe and probe ground across the capacitor? I believe I watched a video where you repaired that Scopemeter. I love your videos. They are super informative without being overly technical. Thank you.

6:40 the fluctuation of the DC resistance is very suspect.

Nice

Regarding the 16A vs 24A, this could be the PP resistor limiting the current. 16A is likely the connector/cable limit. It's meant to protect you from using a 16A cable with 32A socketed charger.

700Ω ESR? That's a new record!

How can I reach out the you please

Just want to ask you whether this unit can work with AC signal or just with DC? Thanks. what kind of signal can be inputted? AC/DC or just DC? Thank you

Hello sir, what do you charge for a service/repair?

How you romove the cover ? Is clips ?

Welcome Back 😍😍

Huge t hanks to you sir! The power went out at my house and took down one of my KRK R7s (wouldn't power on). I opened it up and saw the same swollen capacitor. Took me 30 minutes and a 40 cent replacement capacitor to get it working again. Seems like this happens to many people, sounds like poor circuit design. I wonder how many of these speakers go into the trash because of this! Such a shame.

Schön wieder mal nach langer Zeit von Dir zu hören. Ich mag Deine Videos sehr! LG

I'm waiting for delivery of a "dead" ES-1mkII, which I suspect has suffered a similar fate to this ER-1. The seller doesn't have the original PSU and said nothing happened when they tried to power it up with a spare PSU. I suspect they probably had a positive-tip PSU, whereas these old Electribes use a negative-tip supply. I'd like to think that circuitry offers some protection against incorrect polarity, but maybe it doesn't?

Awesome repair, as always.

Thanks once again for an interesting repair.

Nice! Very odd trail of evidence in this one, with those separate issues. Perhaps previously repaired by a gorilla! :-) Looks like something I would have done!

very nice repair as always. The unknown MOSFET is FDN352AP by former Fairchild Semi.

Excelent Great great work. 4.8V can fried the procesor.

I wasn't SHURE™if you were going to figure this out. But who am I kidding... You R the "FeedbackLoop Whisperer" Always the best mYstery nOvel on the shelf. Thank you for the video. Cheers from So.Ca.USA 3rd House on the Left (please call ahead before stopping by)

Very well done, again. :)

It's always nice to learn how problems can be solved even when there isn't a schematic on hand.

Great troubleshooting! How did you know to use a P-channel MOSFET if you couldn't identify it from the markings?

good work 👍🏼

Excellent result - probably good that you didn't find the faulty MOSFET first, as you could have fixed the issue with the power switch and still had 5V on the 3.3V rail without knowing it.

Great repair job

Q6000 is likely FDN352AP, marking 52APM (M is for datecode).

Where have you been? I thought you gave up on educating folk😀

like a BOSS!

I always like before I watch. Quality content guaranteed with you

🎉 Hi! Nice repair as usuale. Keep up the good work. Regards from Italy.

I love the incremental methodology

Glad to see another video from you! Excellent as always

Interesting repair. There's no explanation for the melted connector. I guess the owner's self inflicted wounds. Thank you for sharing.

It's been awhile

Hi, do you know if there are still working drivers available for the SL990xp here in 2024?

I have a peavey 400 bass amp voltage on the output...what can cause this...??all the outpuy trans and preamp check good

I found this to be a very useful video as i have an Agilent 8563EC (color) and I will perform the same re-capping of the PSU. Would have been useful if you had placed the caps info/part numbers in the description. Thx for sharing.

My Zoom R24 the SD card stopped working. I was hoping the part was replacable. The card won't stay in

Thanks for the video. Is there a way to change the operating frequencies? Example instead of 790-820, to change 606-636 by changing the section? Regards

Nice information sir thank
