I don't want share this H2500, this is dificalt and expensive project for diyers, but if someone can design his own pcb it is posible to build 3 step 2,5kW class-H amp. You can use 2SA1943/2SC5200, but test amp first, before use in PA.
Regards
Step driver with TL072 can't be use for 3 step class H driver,

hi apexaudio
greetings any schematic for diy 3 step supply h class supply
that you might want to share if you dont want to share its ok i repect your
feelings can you tell me if a 3 step supply is used for h 900 wii
1 heating decrease
2 more output power be given out and most of all can such a supply be
used with this amplifier the reason i ask is to learn experiment and how to apply
these 3 step supply for knowledge cant keep on copying have to learn fundamentals so please understand for me your h class power is amazing h900
similiar to qsc isa750
thanking you

H900 can be redesign to work in 3 step classs H with more outputs, and you have heating decrease and more power,

Hi Apex
check schematic from PA amp M10
there is PA Amp with easy linear Class H Stepdriver without IC ...how do you think about this ?
Can I use this linear Class H Stepdriver for quasicomplementary output stage ?
I think it should work because its not switching Rail compare to H900

Your output transistor must be on center of heatsink for maximum heat disipate, maybe you can use only black heatsink, but radiating have wrong position.Hi..Apex, that's my pictures H900 still in progress:
1. Front panel:
2. Rear:
3.

because this I adding white heatshink...I will try it, if result no satisfaction, I will used only black heatshink...One againt, thanks Apex..
Hi Apex,
Can you please provide details about the 10uH output coil?
= wire gauge
= no. of turns
= coil diameter
? is it wound around the 4R7 2W resistor ?
? for the zobel network, can we use 10R + 0.1uF ?
Thanks,
Joel
