those 2 LED in output stage
are those for just protection?
if you have more than 1.65 Volt across them, at working bias
they will block the output from more output current
= clip the top of your signals (current limit)

not bad!
can i build it and get it to work alright?
i guess you will try to make some prototype
because your ideas are interesting
they deserve some real life testing, too
regards lineup

Re: Galactica Project
let us do it, tu italian ami
but let's not do it here ..... no good, you see .... hmmmmmm
Why you have not join my own personally Audio Forum.
Where me & those amigos will make some ReEALLY gOOD iDEAS together.
1. If you do not come ... to my place ... no project we do ... I promisa
2. If you come ... we make un perfecto amplifier .. and post it here in www.diyaudio.com
3. Ultimatum I give to you ... you make your way 😀

Re: inventing solutions
I'm sorry to say that but most of your ideas wouldn't work anyway. I mean the ones related to electronics design, because the ones related to marketing are actually quite good.

yes it's true Eva
at last I'm happy with this Marhevinson
i have just to calibrate dissipator, tension and number of final
sound it's very good

okay.
you just forget my offer to you, Stee
you had your chance, man
but we will not make amplifier together
🙂 will give me more time for my other projects and discussions

Is this really a Levinson no.331? I dont think it is, single ended firstly.
Does the real levinson use opamps?

I expect your right. The 331, 332, 333 are the 3 different power ratings of the same range, so I expect similar topology with more output.
The 334, 335, 336 are the next gerneration of this amp. Its fair to assume the topology is similar.
Its interesting, the plinius sa250 family I believe use opamp inputs too and these are big buck amps too, Im not sure I think they are worth the money, but build quality is very high and as allways in hifi its personal preference.

Luke Im not an opamp fan at all, but I have to admit there are some new opamps in the market now which are very good, discrete cannot compete spec wise wise but there is differences in sound, but then again there is differences between different discretes too. Jeff rowland uses gainclones in his amps now and some say they sound awesome, can be confusing. I believe the best amp is the one that sounds the best to your own ears, one one should compare various amps, component matching plays a role too. I have electrocompaniet monoblocks which is my preference for my speakers and cdplayer. Ive built stochino diy amps with slight modifications and some family members which are musicians prefer their sound, the price difference is in the 1000s of euros. I agree that build quality and component quality is of prime importance.
Hi Homemodder,
yes I followed some discussion on this forum regarding the Jeff Rowland gainclone.
What Im finding is that for acoustic or laid back music my sytem is nice. But if I play any rock, it just doesnt have the dynamics to belt it out. Thats what I really liked about the Levinon, it seemed very neutral and dynamic range was huge.
Having said this the owner had more money invested in cables than Ive spent on hifi in my life and a large power conditioner with wall treatrment.
I have considered building the Stochino, Ive never seen pcb boards around for those on this forum.

The stochino is a complicated design that needs some care because of its speed. Mine is still on veroboard, but sometime next year Ill get a proper board made for it. I dont have the time to design it so Ill get them designed and made by ACD, a member here. A problem with this amp is its very sensitive to board layout and will probably need some mods again after new boards, its a beast to get absolute stability. A change to higher power output fets is also on the cards. Its excellent for rock, thats what I mostly listen to. When one plays trash metal like metallica a lot of amps become like a blur and makes listening fatigueing, this one plays it with ease.
Looking at Jeff Rowland s earlier schematics , im still baffled that he is using gainclones. He had some excellent looking designs. By the look of the 331 it will be no slouch in speed, play rock with ease too.
