There are 2 trim pots, for left and right. I suggest turn the volume to minium and then trim the pot and read the output.
If the amplifier works(output normal), you may check if the meter setup is ok.

Could someone tell me what brand of caps are the 3.3uf input caps on the v2 board are ,and what caps have you tried as subs.i have some 1uf vitamin q would these work?

Hi, they are EPCOS 3.3uF/250V, I think no less than 2.2uF should be used for better bass.

Greetings from France,

I have been reading a lot of your threads posts about the 2050 and am discovering tripath technology and thank you for your great job, but couldn't read everything.

Could anyone tell me :

- whether the Dayton DTA-100a is worth it for discovering the 2050 technology ?

- or if I should do it by myself ? In this case : which is the latest good board ? (2x100W would be enough for my 91dB Tannoys).
Is this one the best ? "TK2050 TP2050 2*100W CLASS-T D TRIPATH T-AMP Board "


Thank you alot, I won't miss to give you my feedback, compared to my EL34 Sonic Frontiers, and maybe my KT88 Music Angel.

Regards,

Hi, I think it's difficult to tell which one is the best, but it's mostly depend on your demand. v1 is for 8ohm and DC supply only, v2 is for 4ohm and support both AC and DC supply. If you need more power (up to 300W), we suggest T3.
I'm sorry for not answering your questions directly.
Or you may visit www.hifimediy.com for more information.

I would stay away from the Dayton DTA 100a as ther is a thread about it's poor build quality. The v2 board with a Meanwell supply would be much better.

T3 board sounds like it could be good, what output inductors does it use?

Thank you.
Before buying the kits, could you please explain me why v1 is better than v2 for 8ohms ?
It uses the same components, except for input power supply, right ?
Thank you.

This is something I would also like to know, disregarding the impendance and maximum output power issues for the moment.

What is the better approach soundwise - V1.1B implementing one STA508 stereo output transistor or V2.0 with one STA505 for each channel?

I have already SURE ELECTRONICS tc2000 + tp2050 two channel board with passive cooling. I would like to have an even better implementation of these Tripath chips, if possible, and with all other proven tweaks implemented.

Baki

We use T106-2 core on T3 board.
