Pop Pulse Tsunami T-Amp

[EdT]

Anyone audition this pretty amp yet ? Its now cheaper than the TA-10 and comes standard with a blue Alps pot !

How does it compare to the TA-10 ?

Doesn't the TA10 use the very nice TA2020 chip and this one the crappy TA2024...?

[Lostcause]

Nope... The TA10 uses the "crappy" TA2024....
I think your comments may offend several thousands of people!

Granted the 2020 is a better amp but the 2024 has it's place and if implimented correctly, can match it.

Ok, well I'm very sorry. It wasn't my intention to offend several thousand people...

But I'm not bullshitting, the 2024 is much more vulnerable than the 2021 in my experience... Plus it has slightly less power given the fact that it is limited in supply voltage due to poor cooling capabilities...

Well ok I'll cut it out, but for those looking for a ready built amp go for the TA2020! (but I do wonder what the beep you're doing on this forum if you do so?!)

Hi Edt,

I bought one for the ridiculous price of €59,-.

My comments (listen with half an ear since I am a new bee to High End DIY)

It is well build en sounds fine on my system, though I am still in the run in phase. It seems easy to tweak (coils, caps etc) and came with a decent power supply.

I can't understand how they do this for such little money! If I throw another 20€ at it I will have a very nice amp!! The only problem is that I have promised this one to my daughter (and the next one to my son...... and the third to my wife

My 5 ct.

excelent sound with a 13.8v 5A transformer. No hard highs.
(I am using it with a audio nirvana 12 inch full range sp.)

Any one who did some mods on this amp?

These are the innards,

I am thinking of swapping the caps and did my first experiments with winding coils (not very successful).

Any suggestions on values are always welcome.

And this is how it looks like inside.

I can imagine there can be improvements when changing some components in the output filter, like using decent MKP caps and MPP toroidal cores to wind inductors with....

But then I'd say just use a better (for insance TA2020 based) amp, they usually have more space for such components... Like I mentioned I'm not too fond of this chip to start with and I think it's still about the weakest link in the chain here...

Hi V-bro,

I am playing around with this amp, to get in shape for building my own "better" amps (as you know ;-).

My soldering technique is improving a lot, hope to be able to solder smd soonest!

Just took of the inductors. I will experiment with self wound aircores here (o,8 mm wire).

Caps need to be replaced too. I am thinking of 6,8 uF 440 V Jantzen foilcaps to replace the noname with caps on the board. Not very expensive, and a nice upgrade I hope.

What do you think?

Peter
