Heyy , just posted topic No: 2000 above !!
What's my surprise gift Mr. Hifimediy, a TC2000 controller ?? Ding , ding, ding ....

I think these boards are REALLY designed for low voltages. You might still get some good sound @ 24V with a T1 or T2 if cost/size is not an issue.

Should be no problem, as long as all parts specs are taken care of properly...

I have a TK2050 amplifier running at a voltage of 55V with no problems at all...

There are other parts on T1-M that have a max 24V rating.

Which are?

Usually they are just some electrolytic caps, ceramic caps, and maybe a relay... Then adapt the voltage sensing, feedback and gain and you're good to go!

we use 25V electrolytic cap on board.

I have attached the picture of the PR1.
Is the controller chip maybe at fault or something else?

It's strange to me too. The part seems ok from you photo.
Could you measure the wires from the resistor RP1 to the chip? I hope the trace is not broken.
What I can be sure now is that the output part is ok, so just focus on the TC2000 analog input part.

That's encouraging for me.

Cheers mate, but that's easy enough to fix then!

So far so good your T Amps just only need a bit bass treatment. It would be also encouraging me to write more on the german Tripath Test page when I (or you ?) find a Modding solution. The page is launched some weeks ago and voila there are currently T1 and T2 (with input cap mods) introduced and a non-modded poppulse. The list will be continued.

What I can tell you that T1 with battery supply sounds damn good with 8 ohm speakers. But the solid state 2 x 40 Watts Creek 4330 is a real giant killer and obviously the T1 could not hold with the bass response. On the other hand the soundstage of T1 is far better. The T2 (Battery/SMPS) with small 8 Ohm speakers sounded a bit bass-shy and lightly unbalanced. Here indeed a pair of max. 6 ohms impedance speakers are recommended. We compare with good classic solid states. In nearly future the reference equipment will completed hopefully with a 845 tube amp.

Hi
Can you give as a link or web page about these tests from the "german Tripath Test page " .
