"Thanks for the reply minniew
Has your amp ever failed?"
The rebuild A400 - no (also pick up at repair shop)
The A1000 - no, but like I said my speakers can't handle it's full power. I forgot to mention that our church also has one of the A1000 and during the past 10 years of use and been driven quite hard I do not know of any failure.

Hi,
r6 limits how far the cap reduces the HF gain of the first stage.
Reducing the HF openloop gain makes the amp more stable when the nfb loop is closed.

Decided to abuse the nmos200
decided to give 2 of my nmos200
to a dj friend who is very abusive towards Amps
He Drives them Hard and clips them to death
without abit of compation.
most Amps never make it for more than 6 months
He used my stereo Nmos200 for driving 4X 8ohm 100w 12inch speakers for 7Hours Straight
And Guess What?
Even with the little Heatsinks I had on it (fan Cooled)
built with non exotic parts
50V rails (well 48.6 to be exact)
The Nmos200 made it back alive🙂
Thanks quasi for sharing this briliant amp with us 😎
Busy constructing the a Legend Stage Master & Nmos 500
will keep you Posted....

Hello DJMARVELLOUS, i have worked on hybrid amps and in mho
are the worst workmanship i have ever seen and i have worked
on hundreds of amps not even stuff forom the far east has that bad workmanship, i have built i lot of amps and would never offer anything like that to a client. The mpsa 42/92 should be replaced by mje340/350. If i where you i would completely strip that amp
the only thing that is of any quality is the box and maybe the
transformer the heatsinnks are far too thin.

I Agree Bruce@bluff
All my dj friends have had many problems with these amps
I have stripped mine & am busy building & testing ncahnel mosfet amps to choose one to replace it with.
dont understand how one would expect to archive driving
4pairs of mosfets from a mpsa 42/92 to92 bipolar?
will try replacing my friends one with mje350 and see if it survives
thanks much apreciated...

djmarvellous said:I agree 😀 but then again they work flawless
djmarvellous, if the PCBs in the latter pics are yours that you made in your kitchen sink, then I hastily and humbly have to remove my foot from my mouth! Re-reading the thread, this may indeed be the case.
Sorry, bru. I didn't mean to discourage... 😱 😱
no prob man😉
I made the pcb with the tonner transfere method
& drilled them my self
not the best looking but hey they work
