Well, we really don't know for sure.
I transfered my whole system. (amp, dac, preamp, active crossover, wiring and so on) To my friends place.
The same system at mine place was playing since the amp was built with no problems. ~1 year.
So at first startup i noticed the my power modules started in a weird way, but everything powered on and worked, just one channel had a hum noise, thought that it was something with one of the rca cables, because there is a lot of them. It played like 2 minutes, then i powered down the amp, adjusted the wires, pushed the power on, and kabom,
Well we think that its was something wrong with the whole electrical system, because he had problems before with electricity in general
So i have the amp taken apart now, and from what is visual there is nothing too major, resistors in the input side, and couple small transistors.
Well we will see if we will be able to repair them.
i've sent an email to Andrej and he replied quick, i really hope that he will help me with this one because i have purchased like 16 M modules and 8 L modules...

Good for you! I'm obviously insignificant since I have bought only one pair M modules...
Bah, with 10 modules bought, I had worst treatment than you when 3 or 4 of them die out with no apparent reason, most of them one day they refuse to play.
With months after the date they were bought not only I was not offered replacement but was denied any kind of help service them by myself, not a hint.
This after numerous emails.
He end up being sarcastic too when I simply suggested that he should rise the price and have better support like Hypex does
Worst treatment period in my audio life (diy or not)
It's up to you, what you value most, low price or support. You have been warned

I wish you best of luck, but I would suggest you start looking for help somewhere else ...
Hi Andrej,
So finally, what is the ideal capacitance, per rail, for FO L ?
I had the impression of 10mF. Is this correct ?
Thanks
Hi Rob!
I have 2x 1200A180 PS. The reason for going 45 volt was more current delivery when driving my 4Ohm speakers (going down to 2.4Ohms).
But whenever LazyCat brought his FO 1.4 or M with A400 PS it sounded better. The difference is not big. But it is there.
As for 2 Volts difference. The capacitors are Mundorf. The spec says 63Volts but that is working spec. The limit is 80Volts (the number competition would specify).
Mine 1.4 has most of the L tweaks done except the last one. The last one is a lot of work. Too much actually so that is why LC is bringing out new modules this year. Drop in replacements for 1.4 modules, 1.2 modules too. Also simpler to calibrate bias.
I agree. The modules are/were priced cheap enough. Repairing a module is not 30 minutes of work. After few hours of work and 2x shipment, new module seems like a good option. I am able to do through hole stuff. SMD no way.
I believe that LC is working on DCoffset and OverCurrent speaker/amp protection. Hopefully soon.
This could solve some issues. with burned output.
The support is module oriented. Dead module for no reason, send it back. If no short done on the amp I am sure LC will honor the warranty or at least attempt to repair the module.
As for 1k investment. LC will keep the size and holes of new modules the same, so new modules with new electronic design will fit and keep your 1k amp box working in future.
There are bunch of us who can deal with SMD. Plus there are no new FO 1.4M modules available.
When I was buliding Pass stuff I was not asking Nelson personally to do the tech support. Its sufficient to provide enough info for DIY community builders ...
No way Hose
I am interested in new modules but I am not ready to throw old ones to waste bin, as I suppose many others with the problems are not.
And for the warranty matter I'm quoting the answer I got from LC in original and translated:
"Garancija za FO module je 12 mjeseca, a zadnji FO M bio je prodat 2016.
Lepi pozdrav."
"Guarantee for FO module is 12 months, and the last one FO M was sold in 2016. Greetings."
