thanks guys! Recently i used MJE15033/34 pair, they are great but they have too low V and all of them have reversed pinout according to MJE340/350 which are often fakes in Poland.
Sakis , what are the mistakes?

To220 and To126 always have reversed pin out. That is the standard they are made to.
Try MJE15034/5 They have superb SOA @ higher Vce. ~350mA @ 80Vce.
They also have improved speed. typical fT>60MHz over a wide range of operating currents.

@apexaudio and all other DIY
have add Bootstrap and NMOS VI Limiter like in ARCAM
latest design improved QUASI NMOS
could this work or firework after first test ?
Optional: TRIAC DC Crowbar protection,
VI Limiter for BJTs and electronic turn on/fast off
this amplifier design dont need relay for speaker connect/disconnect

Have finished today another NMOS PCB and Schematic
Does Bootstrap working like in the schematic or is it wrong ?
want order PCB for DIY but before....does somebody find any faults ?
Have add in NMOS VI limiter, Balance in, Relay free electronic Turn on delay/fast off Triac DC Crowbar protection like in commercial PA AMP
ideas for more improvement ?
waiting for good news

Nmos200/350MK2
quasi,
Do you think it worth while to emplement the Baxendall diode circuit that's in the 350mk2 to the Nmo200? (D3,D4,D5,C12,R26).
I have some BUZ902 DPs that I want to use for outputs,any problems in doing that?

the Baxandall diode and the capacitor are there to emulate the load that the upper BJT gives to the driver.
I don't expect the load given by an Nchannel device to need identical components to emulate the FET.
But, it would be really nice if some could confirm what changes, if any, are needed to go from BJT loading to Vfet or Lfet loading.

Thanks AndrewT.
Maybe someone else can chime in on this.
The Buz902DP is an excellent lateral mosfet,even though they are hard to get.
I'm looking at some Alfet N channel ALF16N20W to use in the Nmos200.
They are easier to get and cheaper than the BUZ902 series and they are made by Magnatec.

Hi Quasi, how are you bro, about this amplifier, my friend gave me 5 pcs. of this 2sk1530 and Im wondering if I can use this mosfets for this amplifier and if its not to much to ask can you please mail some latest schematics, layout and construction instruction for this great amp. thank you very much bro.😱
hi quasi, can i use the 2sk1530 for this amplifier, my friends gave about 5 pcs of this used mosfets, can you also mail me the latest update this amplifier @ jhoel47@gmail.com ,thank you very much bro.😱
how is the value for quiescent current in amplifier Nmos200?
what regulate with VR1 and VR2?
VR1 is for quiescent current?

Hello Quasi.
Can you send me pcb file of NMOS350-500 for Eagle or something like that?
Thanks in advance.
