KentAudio "Construction ONE"
HEllo good people!
After 18 months, reading diyAudio threads, articles and
books of all well known audio gurus
(Pass,,Curl,Slone,Hiraga,Stochino,...) ,and examining all
kind of circuits and topologies, I finally designed my
own compatibile audio system.
The work wasn`t easy at all! My knowlege of solid state
amplifiers was pour(still learning), and I spent days and
nighhts simulating all kind of circuits and building two
ab-class standard amplifiers...
The "Construction ONE" system is actually my version of
class-a single-ended mosfet source-follower (used for
current amplification) and current-feedback high-speed
preamplifier (used for voltage amplification).
I would like to hear your comments about this circuits
I`ve designed before I start pcb construction.
The simulation results:
Q9, Q10: 4.89mA
driver stage: 58.8mA
power stage: each IRFP240: 2.8A
each IRFP250: 4.2A
Output power 30W
Input stage: 2mA
Input voltage for full output stage power:700.6Vrms
simulation result of slew rate: 214V/uS
Is it so uninteresting?
Hi,when you really build it,then it is very interesting.
you didn`t read the thread ,I think...
I was asking, what do you think about the circuits and should I change somthing to improve it...
Question for a power follower: would it be better to bias the driver stage (MJE 15030) with the simple ressistor and does ccs improves something in this case.
The voltage gain stage is seems like modified CFP. With the same part count you can built diamond buffer. Which is better?
