NEW Audio amplifier kits, modules and many others.

[Cristi]

The recent delays have official explanation, please read here: Festival courier services far from ?express? ---szdaily????????? i would like to ask to all the customers who haven't received the packages yet to wait patiently till they will arrive, even if the tracking informations is not updated since long time for some destinations.

Just to let you know that my amp arrived in DC, but I left the country beforehand.
Therefore I will not be able to run the tests here as described to you - my bad, I should have ordered it earlier.

I will test the amp upon my return and will let you know of any issues.

Have a great 2011!

Happy New Year and all the best wishes for everybody !!!

That new one looks really interesting because of the 'on-board Mains IEC Power Connector'. That should make it and a TA3020 Audio Amplifier v3d basically plug and play.

I have read a good part of this thread but I still wondering...

TA3020 V4 or TA3020 V3D ? I'm confused

V4 seems "better" and more simple for beginner like me. But there is no options like changing caps or BIPS input...

In the other way V3D have BIPS, lots of options but I don't know which power supply to choose and if I will be able to "bypassing the rectifier bridge".

Anybody can advice between the two versions ? Which one may sound better ?

By the way, what the difference between AXXXSMPS and SMPSXXXR power supply ?

All,

I am new in this forum. I am thinking of building the 300W LME49810 Audio Amplifier. Do I really need two separate transformers with different voltages?
Best regards
Denis

Denis,

for each module, and even for two modules, a single transformer is enough. for better performances i recommended to use separate supply for the driver stage and power stage, the driver stage should have with about 5-10 V more.

Gregbny,

the TA3020v4 has on-board power supply, but has less flexibility while chosing the options compared with v3d + SMPS800R for example.

for the power supplies, i considered to call them with letters and digits, the digits represents the nominal usable power for audio amplifier supply, and the letters designate the class. A are classic, hard-switched, R are resonant, soft-switched, and QR are quasi-resonant, a combination of the previous two classes.

Cristi,
Are you still experiencing shipping delays using normal post to the US?

No.
Look at the datasheet for circuits that use one centre tapped transformer producing one dual polarity supply for the whole Power Amplifier.

300W, into what? a resistor or a speaker?
What impedance are you expecting to drive to 300W?

Christi,

I mailed you through your website but have had no response.

Do you have a personal e-mail address where I can contact you.

I am interested in possibly one or more of your 2000W SMPS with some modifications.

Thanks.
