hi mr mile🙂
i want build sr100 ampli version john bali
he use 1k resistors instead 2.2k in his pcb
which one is correct?(2.2k or 1k?)
please attention to red circles in photos
my traffo is 2*33v ac
respectfully

Use PSU10 pcb from post #1861 for stereo but with 8V2 zeners and 50V caps.You can use BC547/557.

i have 4cap 18000uf 71v.can i use instead 10000uf caps in psu10?
in my local city i dont found bd241/242.can i use tip31/32 instead them?
thanks mr mile
i will make sr100 and psu10 a few days later and share it pics here
again thanks for your answers
respectfully

much activitys to christmas time.
Aaah another nice board worked out.
Now i understand more your "limitation" in time Marc. 😛 😛 😀
Mile is showing us a new A- Amp in 100W.... goes with 1837/4793...

Difference betwen b500 and SR250 please
Hi Apex !
Refer to POWER OUTPUT. What will be the difference betwen B500 with 4 pairs transistor and this SR250 with 4 pairs fo transistor too ?
1. Will they ( SR250 and B500) give the same power output ?
2. Will they give the same quality sounds ?

SR250 can work maximum with +/-60V DC rail, B500 with +/-80V DC. With same rail voltage power will be same but sound must be different. SR250 use folded cascode VFA topology, B500 use OP amp and CFA topology...
with 5 pairs final can i give +/- 90 Vdc with 10A for stereo ?
