I have a F112 v1 with no power problem. I live in Australia so I plan to do the repair in accordance with the instructions on this thread.

First question are the capacitor values indicated by Randy for the f113 the same for the F112? If someone who has repaired a f112 could confirm this.

I will replace the two to the left of the transformer. Is it advisable to replace the other five at the same time or is that part optional?

Thank you in advance.

Here is an actual step by step video I just uploaded to Youtube of my Fathom F113 power on capacitor repair. Thank you SOOOOOO much jdandy for creating this thread a few years ago. I hesitated to join this forum as I am quite busy, but felt like it may be good to help get the word out as there are likely many others experiencing this same issue. I also obtained most of my information for the repair form this thread and am very thankful it was "findable" on google, so felt compelled to give back to this community.
If the admins would like, it might be good for me to create a new thread dedicated to the video which can then be "stickied" as I feel this post might get lost in this long thread...

I want to humbly thank everybody in this thread as I have read each comment many times looking for information and you guys did not disappoint! Great Audiophile community here. :)

Apparently this is very common...a friend has a six pack of F113 v2 subs and he is on his 4th and 5th failure out of six subs in less than a year. He sent #6 in as well and told them to fix it proactively as he's about had it with the issues.

Chad, see my post above. I made a video to help everyone. My sub has been working flawless for weeks now so I'm confident of the repair. Message me if I can be of help in any way. I might need to get my video posted in a sticky because it will likely get lost in this massive thread.

I joined audioaficionado just so I could say thank you for this thread...really appreciate the awesome detailed notes, parts list, and explanations for the repair of a "dead" fathom. Will post more later, just a quick hello for now. Looks like a great site overall too; can never have too many audio sites to follow!

Thanks Masterlu!

A little about me and my Fathoms: I bought the first pair of F113s sold in Canada about 15 years ago...my how time flies. I bought the second pair some time later. Had a few issues with a couple of them, I think there was a "coffee percolating" sound from one after a while etc... Warranty service was very good and they traded out for a new one I think. I recall having an issue with a different one and Barry Ober (Soundoctor) was the tech support guy and after learning about my back and forth issues he authorized a replacement sub for me, which was above and beyond. I had changed one of the dsp units in one sub, can't remember why. Then after that I had many trouble-free years. Recently one of my subs started humming a bit more than it used to...I put the xlr input into the other input and it seemed to help. I get the impression a little hum has started to come back but still tolerable in my very quiet room so far.
The other day, I think after a short power outage, I noticed that one of the subs wasn't on...went through the process of checking the outlet etc... Eventually came across some posts which linked to this thread and it sure sounds like that is what the issue is with my dead sub. I don't mind giving it a try and if all else fails it can be sent to JL.

Not sure I have confidence in the service section of the Canadian distributor so I was thinking that if I'm going to keep these subs indefinitely then it may be worth sending a pair at a time to JL in the USA to "recondition" and bring back to a like-new state. The $400 cost is not too bad but the shipping may be a PITA. Or I could sell them and try something new since sub technology seems to have advanced in the past 15 years. Decisions decisions, lol.
