Hi syaelend,
using CD4069(cmos)& 74HC14(TTL) on 5v bias, fsw will reduced to 120KHz to 180KHz max.
using CD4069 on 12v Bias fsw will increased (275KHz)
Using 74HC04 on 5V Bias fsw = 375KHz
Regards
MANOJ

Hi All,
Success of my (smd ver.) AUD1000SD/1500SD , I start to design a small AUD500SD {size L=3" & H=2" vertically mounded} its for home theater purpose(those who are loved HT)
attached my design 🙂(not completed)
max. supply +/-65V
max. output 1000W@2R, 525W@4R 260W@8R load

Dear Mr. Manoj,
Is there any issue if I substitute op amp IC from TL071 to TL072 ?..
because I need one more op amp for make a Balance Input.
As I see on the datasheets that both IC have same internal circuit..
Thank you
Syaelend 😎

Hi Mr. manoj,
I have a question about the inverter IC,
Is there any special purpose to use 3 inverters on serial mode before feed it to the
HIN of IC IRS2110 (Picture 1)?
What happen if we only use 1 inverter each before feed it to HIN and LIN of IC IRS2110 ( Picture 2) ?

I don't know if some one has ask about this before if its please forgive me.
I try to build class D based from IRS2092 but I can not find toroid T130-2 for LPF locally and I think to use ET49 from old TV PSU yes I have an LCR meter to wind the coil to value I need but I not sure about use gap or not gapping for this purposes. can some one shed a light to me in LPF must I use a gap or its must be gapless ?
thank You

Hai manoj sir ,
I droped your 250sf due to the presence of smd parts, cos am not gud at SMD & dont have soldering station for it. So once again am going to explain my need, sorry for that.
1. I need an Amplifier for SUBWOOFER. But right now am confused in selection of subwoofer. Do i need 4R or 8R subWoofer which is ment for Home. But am certain about the wattage & size ie, 250W 12". Please can you help me.
2. For this which Amplifier should i use.

Dear Mr. Manoj,
Which component need to be changed to speed up the Oscillation time.( I mean not the Frequency).
or is possible the system can oscillation without Input Signal?
Thank you
