Died by age not by usage I think. My carbon was rarely used. I have the same problem, same caps, all four are bad. Bad quality so who got these caps from the same group buy have to be cautious. My amp is taken apart on my workbench for months I have more serious problems, illness in the family. I hope I can continue the repair in the near future.

I think my caps came from the group buy organized by @sorenb in 2015. 680u 550v from "FTcaps Germany". (These were overkill because my carbon was 400v). Maybe bad apples or any other cause, the bought volume was enough for more than 10 carbons. I think I would replace the caps in your place in the positive supply too, less fuss.

Congratulations! I have the same problem with my carbon. Both of the big capacitors in the negative supply died. It happened a few months ago but I can not persuade myself to start the repair until now. As I checked it again I see one of the capacitor in the positive supply is bulging too. These are from the first group buy I think. Where are yours from? So the advice is replace all the sands (and check the passives in between) the less time consuming? ;

As I thinking about the show the similarities with Mare of Easttown strucked me a bit late. Can not be a coincidence I do not know which was first. It does not matter both are phenomenal. And both because of the lead actress mostly. ps.: I am not the first who discovered the similarities and Happy Valley was the first I see.

Finished the first season. It was so good as True detective, Fargo or Mare of Easttown(always the first seasons) or better. I always thought tv shows are something like chewing gum most of it are but there are exceptions. So I am watching a few lately.

You are on the wrong forum. You can start here Google QN90A black screen I am not teasing you the info is there but you need to work a lot to find it. There could be a hundred cause. Do not open the box if you have no experience with high voltage it could kill you, only try the other tips! I am answering you because I had to repair a 3d lg TV myself because the service only wanted to do it for almost the full price of the tv. It was a few months to find the info, parts and equipment but I had no choice because you can not buy 3d TV s nowadays. How can we watch the next Avatars?

I think I heard about the need of that or similar transformer before. I got my 4th boost against COVID, I can wait😀

So the project continues than? As I remember the powering was the main problem always or not?

Is he a moderator here? I would be very surprised.

I thought so myself before. It seems 1984ish delete a person good or bad from the history. Probably it happened before, my inattention. Got a message "不错的耳机" that I have not find on the forum.

@HVRV's messages disappeared. Not that are missing but the remnants are strange. Who could do this himself or the moderators?

To the others: Why this is personal to me, this is not my case. Kevin maybe on Headwise spoke about the mini amp first but more than ten years ago I am sure. I am waiting for it from then. The project restarted a few times. When the head-case server died I told somebody here it was because of ministat amp restarted, Ill fate it could not be accomplished. The truth is I do not need it not travelling much hardly can walk. I am accustomed for the waiting and there is no really good portable amp, I am curious. And now this situation. Yes, I do not like thiefs, everything is stolen some want to eat some want a new Tesla.

You do not need the PCB was enough.

Transistors, the circuit diagram of the amp that counts would you compare them?

So China is the country, what a surprise...
