My bass is dry. What can be?
20x 10.000uF 80v caps with this and 16 pairs of 2SC5200 1943.
2N5401-5551-92 MPSA42 exchanged for.
16 irf2807 mosfets were used.

hi soerdjanto
good job......................
please can you share schematic & pcb layout
Thanks

NSL32 not connected. Influences?
Tested with four pairs of transistors in the outputs. nothing has changed. only decreased potency.
Much movement of the speaker, a little bass.
I called the Direct +-HV transistor. Nothing has changed as a bass.
4 18 inch speakers 8 homs. quality bass sound bad.
Help me please to solve this problem?
high definition
An externally hosted image should be here but it was not working when we last tested it.
I mean please post your schematic too, only pcb layout is to less
A amplifier is very complex thing
Can your software compare pcb routing with schematic for faults in pcb design?
Im using free pcb layout software with projekt proof, software compare layout tracks with schematic for faults in routing
but I dont have built H900 yet because very satisfied with NMOS
have built QUASI (power amp under development) NMOS300/500 ....is working since long time with 100V DC like hell and bass like earthquake
ok very hot but will try to add class H step driver in future

hi Nmos
greetings can you please tell the name of software which compare pcb
routing with software

Sorry, I dont know cant help you, dont have built H900, ask APEX or other DIYer
I can only say,.... very satisfied with NMOS amp its a really performer and bass like earthquake
look here we want try to add Class H Stepdriver in NMOS for reduce heat and dissipation
http://www.diyaudio.com/forums/soli...-nmos-amp-class-h-stepdriver-possibile-2.html
NAD 208 is working N channel with step some bipolar N designs too
cant see benefit for BJTs output stage for high output power
.... it can more cost effective in mass production
about 0,50 $ pcs. for 2sC5200 and 2SA1943
compare to power mosfet about 1 $ pcs.
second breakdown is high risk, Did see failure burning up output stage against second breakdown very often
often sounds mosfet output stage better, you can driving pushing harder and more rugged
bjts no thanks
