What amp module is this?

[MikeHunt79]

I bought a few Tripath 2020 amp modules recently, as spares and repairs.

I was wondering what this amp module is and where I can get more info on it?

It seems to have a built in pre-amp and speaker protection which is pretty nice.

Pics:






Excuse the quality pf thepics, they were taken with my phone...

It appears to be branded "Hi-fi Audio"

and also says "Version:2.5a" on the PCB...

Also, when I plug power up to it the red "OVER" LED light up straight away... I have yet to hook it up to any speakers however...

Where did you get that one from?

Why not ask the person who sold it to you (I presume it came from "gatesof")?

At a guess, it looks like it perhaps originated from eBay seller "I wanne Buy" [sic], who presently appears to offer a similar "Hi-fi Audio" branded TA2020 board, "New Ver PCB 25watt CLass-T amplifier for Tripath TA2020", sans speaker protection and 2 LEDs:

Personally, if you haven't already done so, I'd concentrate on fixing the Charlize!

Cheers,

It was gatesof, I've sent a message but have yet to hear back from him/her, hopefully they should remember.

Cheers, that does look very similar, I've been doing quite a bit of searching for various TA2020 modules and that's the closest one I've seen so far. I'll ask them if they have any more info on these modules...

Well, I've been pretty busy this weekend, but it looks to me like it might just be some lifted PCB tracks around one of the speaker outputs so should be a pretty simple fix.

I'm sure the Charlize is the best sounding of all the TA2020 implementations but it is quite costly in comparison to the "Iwannabuy" version. Iv'e ordered one and will compare to my modded Lepai.

Iv'e received my "iwannabuy" TA2020 board. It's a bit different to the one in your pictures Mike. It sounds very good though. Will bed it in a bit and use it to power my compression drivers/waveguides in the high section of my home HiFi.

report back soon.

Nice, I still haven't got my module working yet, I'm glad to hear it sounds good.

I'm still playing with my lapei right now, but as soon as I get this module going I'll let you know how it compares to the Charleze

will it be possible to put up the picture of the unit if it produces "good" sound?

thanks,

I'm currently building a case for this. Once Iv'e finished I will present photos. It is a nicely implemented module with good components.

cheers,

Iv'e finished my "iwannabuy" TA2020.

Some photos here:

Sounds very nice.

Iv'e utilized an old 3.5" hard disk enclosure and bracketed the laptop power supply into the case. Used a LM388T regulator circuit to get the voltage to 13.5v
