before i go on search, can i find somewhere the pdf for the FO1.4L , to see if it is matching my already made case/psu ?/
sifis_samos,
I don't think LC made the PDF publicly available - you will need to go through the thread and find posts that share/discuss the specs and requirements, and also see what other builders used.

thanks for your reply! i read more than 50 pages.. my head got dizzy!.. problem is that info is scattered.. mmm... needs patience!..
well if someone reads, i already have mounted in a case, one Torroid with one wind (so, common traffo for both chanels) 50-0-50 1.5KW , and 2x47.000uF per chanel (Each chanel has its own bridge and caps). so i have about+-70v... buyt i gues if modules are nowhere to be found...i might have to look for something else.. its just that, it looked apealing the fact that this amp needs the minimum measurments etc.. sounded suitable for an amateur as me..

Understand that you would like to utilize the power supply that you have; however let that not be the basis on which you choose your next project. 🙂
If I may ask, what speakers are you using? There are other projects that are based on prebuilt modules. And there are other projects that are fairly simple builds and don't require many measurements to be done.

i have a diy pair, very well designed, and performing floorstanders speakers, by a very well regarded Greek audio engineer.. dual 6.5" seas+ tweeter... about 91db sensitivity, and -3db at 39hz..
My main idea is to use parts that i already have... and i have many.. past decade i started and left half finished many projects.. well now its time to sort some things.. to use some, and whats left to sell them..
So the idea here is , to build a decent powerful amp without spending much.. i just need modules.. not something expensive (cause thats not my main amp project).. something easy and reliable, with minimum measurments (due to lack of specialised knowledge by me) not necessary high end stuff.. FO1.4L looked ideal..
so if you have something in mind, for something decent, operating at +-70v , 200 to 300 wrms at 8, able to work at 4ohms, please share..

sifis_samos,
Off the top of my head I cannot suggest any simple projects running at +/- 70V. 🙁

I found a pair, of FO 1.4L here in Greece!..
🙂
I am considering buying it.. first i want to read a bit more about it..

Is lazy cat alive? First post for this thread was just edited by him?
p.s I still have FirstOne modules for sale.

Best sounding amp I have ever built. Transparent to a fault. The modules are worth twice their original price, IMO.
Hey,
Andrey strikes again with Ubiq, or should i say Uniq or Ubicube..oh nevermind.

Well its to be hoped his 36K amp is more reliable than the modules he sold here, and that he offers better support . . .
Hello Everybody,
I am looking for two First One 1.4L modules.
I have two modules but one of them died and I can't find the seller who sold it to me at the time.
Thank You and i hope, that someone has..

Interesting article. This explains why he dropped out of the DIY scene. I'm glad I built one back in the day. Best money I ever spent on a power amp build - without question. IMO the transparency and articulation of each and every note is so clear it's scary. Some people/engineers/designers are just born with a gift. I'm just glad he provided his First One modules to the DIY community. I know there many members sore he left us hanging with no support. Clearly, he was destined for greater audio ambitions.
