Try adding large caps to the12V input like described further up, i only could grab some 4700uF Nichicon caps locally, but they brought back the lack of low end (god knows the t-amps have detail up the whazoo)
I may pick up larger input caps if i ever go back inside the TP10 MkIII to do other stuff to replace the ones i have now.
Try that with larger caps as Arjen pointed out and it will make a huge difference on the cheap.

Whats the impact with this mod?

Actually i am trying really hard to unscrew the chasis as I am afraid i might go way over what i intend to start with and end up spending more time on modding then enjoying the music. 😉

Re: What about TP40?

olev said:
Look here for TP40 - http://www.tpdz.net/produce.asp?id=11

TA2024 with integrated PSU - and a transformer PSU with nice capacitors and LM1084 5A regulator after it not PWM PSU. A quick look on ebay showed it's already available. Anyone tried it?

Dude, WHY? 🙂

I was pretty content with my TP10 Mk3 + caps. but that thing is tempting.......would prefer that over my TP10 Mk3

Like i said in the first line, it brings back the low end, it is much more balanced if your bass does not get starved, i started to worry it's actually my speakers not going low enough (despite the many reports that they do)
Now i am happy enough that i may only still attenuate the tweeter a little and play with different quality parts on the xover instead of hunting for a completely different speaker set.

Saving my money to eventually build something based on the Alpair 10 FR drivers, or perhaps a A10 FR + A10 WR design, but that's a story for another thread 😉

Arjen: is there such a thing as too much caps on the 12V line?
I want to try some of the 10000uF caps my friend picked up from parts-express, but 1 is as much as i got now and 2 is more than doubling it.
I just like the idea that they are smaller (physical size) than those i got now, and i may be able to find a better home inside the TP10....unless of course that evil TP40 gets to me more....

I thought the bass was pretty good in my system although its a 86db pair of usher 520.

I am thinking what it can achieve in a FR, and am actively looking for one.

Bass is whimpy on my BIC DV62Si w/o the caps on the 12V line.

Oki i have to be fair, I am not someone who is reallyinto bass, but i have some tracks where i active seek the bass for, and most amps fail that track, its actually acceptable for me using the TP10.

Should i go for the mod on the 12v line? I am so afraid.

Re: Pre-amp

ArjenShenzhen said:
Hi there,

Ive been working on exactly that, changing the sound to a different flavor using a pre- amp, or to be technically correct a valve buffer.

I have designed together with a good friend from Germany a buffer specially for the Tripath IC series, it uses a 12AU7 valve, and feeds on only 12 volts, because it has a DC-DC converter inside, making about 42 volts max as plate voltage.

This set up i have been testing over the weekend here, and wowee! that sure sounds nice! it adds the warmth of a valve amp without harming the detail of a T-amp, its fantastic!


Hi Arjen,

IMHO, I think you should add (at least one) extra switched input to the proposed pre-amp / buffer

cheers..

I was considering getting a socket and a plug of the right size and trying it externally, i ended up soldering inside, but maybe you could try it externally and once convinced go to do it inside? 🙂

Go for it Marcus, it's a really simple mod with a noticeable improvement to the sound, you will be glad that you did it! 😉

adding capacitors

marcusdeming said:
Hmmm ok so can someone give me a board shot of which point to solder those stuff.

So it will have to be pp caps 6300uf ?volt...??

i hope it wont end up like my preamp that i overmodded

Yeah 6300uF or a bit more 25v or > electrolytic across the supply.

What did you do to your pre-amp??? 😕

I changed almost everything on the original pcb. and i recase the whole item.

Just solder it to the 12V jack. on the center riveted piece and the left flat piece, loocking from front to back.

I meant to clarify my bass statement a little, it changes enough to make low cello notes sound "right" (to me), low cello notes is my measuring stick.
W/o the mod they sound thin.

Arjen, now i have a pre-amp question too.
My tube headphone amp (Comes from ShenZhen too, Audio capital of China?) has a pre-amp out and it states the pre-amp voltage as 10V RMS, what's a save limit for the TP-10? As line-level is around 1V somewhere, i guess i see if google has an answer for me there.
This is interesting after realizing how much different my USB DAC sounds straight into the TP10 vs through my solid state headphone amp into the TP10.
The resulting sound is less dry and analytical and instead takes on the musical and fun characterisitcs of the headphone amp.
If i could combine the tube sound of the amp headed my way with the TP10 i may have a really great combination in my hands.
I just at this point have zero clue about the 10V RMS.

Thanks,

Daniel
