hi manoj i have managed to configure cd4049 . now the amp is working o.k .

your amp has great clarity in mids comparing to irs series amps. congratulations.

about the output inductor it is the same case as irs amps . i started with 64turns etd 42 but outputs were hot . so i switched to 22turns etd42 they became cool . my output voltage is +/- 48vlts; outputs are irfp250n, gate resistor 39ohms .
>>>the 3.3kohms 3watts resistors for dropping voltages 6.3volts get hot i don't think they will handle +/-85vlts.

now i have to find the ttl ic 74hc04 series because the sn74s04n did not work in my case.

thank manoj for such a good amp

Hi stewin,

thank you very much for your appreciation.

for good low and mid use T106-2 0.8mm wire 59Turns.

use 3.3K/5w(75V supply) it will heat little but not burn

Regards
MANOJ

Pin 6=3A, Pin 5=3Y
Pin 7=4A, Pin 8=4Y
Pin 9=5A, Pin 10=5Y

Just need couple of capacitors for amp board, 10p, 10n etc then it will be ready for firing up! I used IRF630 in power board hope this is okay as other version used 10N20!

Is the any issue if I use 10uF 16v capacitors?

Default Where to find aud600 parts at India

Hi Manoj: I would like to buy some IRS2092, high power MOSFET, inductors. Can you please let me know where in India I can buy them, Culcatta/Banglaore preferred.

Or any online shop in India to check price and availability.

Thanks
Raj
