TA3020

I do have good news my fellow DIYers,

I will soon be selling a new Design TA3020 board that sports around 150 to 200 Watts per channel, ive been testing it these weeks and i do LOVE the sound of it.

When everything is done i will post photo's. This will be as all my boards are a fully finished PCB, all you nee to do is connect it to the PSU/Speakers/source.

Greetings,,

Arjen

New TA3020

As soon as testing is finished and i have chosen the best mosfets i will post all the specifications online.

This will be soon!

With thanks to my friend Cristy for designing and advice help ! your a great engineer!

Greetings,

Arjen Helder

Hi, funny, it's the same for me, I'm working on a 2x500W version and also on a moderate power version....

I'm testing with them, so it can still end up in a 'back to the drawingboard' situation.

It's a great chip and I am glad the availability is still good.

Nope, but I did with the TC2001...

I used Neutrik transformers here... NTE4, but I've also had good experiences with NTL1 and OEP A262A2E, Amplimo, Lundahl......

Interesting 🙂 what's your favourite ?

Lundahl LL1592 is really great, but although some give bad raps about them I love the OEP A262 series transformers. The Neutrik are great because they are very small and very affordable AND still formidable quality... I have tested most of them on a Neutrik A1 audio analizer and most manufacturers are quite honest in their spec sheets (like freq. response..)

In general Lundahl makes the best transformers....

Hi,


Indeed the Lundahl LL1592 look great but the price :bawling: i don't know how much the ta3020 module will cost but it's probably cheaper to bridge them than to use the lundahl.

Does a passive pre amplifier could work well with this kind of transformer ?

Well I was lucky I didn't have to pay them myself, but was unlucky the preamp I built with them wasn't for me either...🙁

You can certainly build a passive pre with transformers and like Col said the Neutrik have excellent specs too and are really well affordable... You can always upgrade later when you may ever win the lottery 😉

New TA3020

Arjen,

I am very interested in your new TA3020 design. I am in the market to build another amp now. I want something that is class D and around similar spec to a UcD180. Will your design use a dual rail 45v power supply? I already have all the components for that. I'm hoping to just buy the modules to complete a stereo amp. With the economic situation a UcD180 is almost %40 more expensive than when I last bought one.

Guys, I already got mine working, not to full satisfaction yet, a few minor changes need to be done and it's ready to release...

I'll post here when it's available...

(I'm talking about a design with dual to220 fets in the power stage and ready made inductors, power supply on board so only a transformer is necessary.. Operating voltage depending on voltage sensing resistors will be between +/-20Vdc and +/-60Vdc, power will be about 200W/ch...)
