Hi!
Anyone with knowledge on class D amps...question here, can this inductor be used as alternative for 220uH choke coil on AUD600?
Thank You!
(I wonder why the contributor has gone silent, It's been a while, i'm currently collecting parts for AUD600...guess I needed guidance.)

Thank you Manoj, I'll get back to you as soon as I have completed one board for a test..
I will be using these pair for the inductor...

My new AUD600
Would you like to share the details of your New AUD600....exactly want to know what is NEW in AUD600???

Hi sir manoj
you was started your AUD600 from page 266 and this is link

have nice time diyers
I regularly follow the thread but haven't noticed crossover for Sub, can you please let know the post#
Thanks

Thanks Hadi. I thought that is for all range sound enhancer. How about your car SMPS? I started one, only made the transformer. It's ETD49, aiming to get 580W.
I'll inform you the progress.

Dear All:
Is this core suitable for Class D amps? any other suggestion?
T157-2 Micrometals Iron Powder Toroid
Thanks

Hi Raj,
any TXXX-2 core can do the best for class D amp filter.
EQfor AUD600 is a crossover for full range and you can modify to a sub crossover fixed frequency one.
My AUD600 Rev3.0 is suitable for any type of filter core like T106-2,ETD,EE & EI core with gap and supply voltage range will support like +/-35V to +/-85V and IRFP250N will support fsw up to @500KHz range with cool.my only problem was HF little low (using ETD,EE,EI with gap)compare to LOW and MID,but it is satisfactory.I am not started the PCB yet.

Hi Manoj,
use accurate LCR meter to measure the value of your inductor. maybe your ee type filters don't have enough inductance to reach a good cut-off freq. also as i calculated before , in lower loads , we lost some higher frequency and we should increase cut-off freq.
anyway , please delete some of your PM so i can give you my e-mail.
Regards
Hi Manoj:
Thanks for the information about the core. I am searching digikey and they have T106-2 only, they call it FIT106-2. Is it good for higher voltage like +/-85? or should I go for T157-2.
would you please share your schematic of AUD600 ver3.0? I am very interested to build one for me.
Cordially,
Raj

I'm sorry friend, I don't have any of my past project files since my portable hard disk was stolen by muggers in Croydon, UK. So I lost everything. I came back to Sri Lanka a few months ago and started DIY projects again.
Anyway I will search those project files in my friends PC. If I'd be lucky I will share those for you all.
cheers!
