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.
I've read somewhere on this threat about improving the bass response by replacing the inductors with Wurth. I have bought those wurth inductors, but been busy with other project, no time yet to play around with my T1. But I've replaced the input caps into PIO K75 and it can increase the bass response.
But I agree, with the price & simplicity hifimediy tripaths are hard to beat. Throw in some DIYers craziness and they will become great amps.

that sounds very promising. Looking forward to your results with the new inductors.

I believe these T1 boards are bridged, so you'll need one board for each channel

I believe these are hongfa JQC-3FF 24V relays
JQC-3FF-24 - SPDT 24V 5A PCB Relay

probably other vendors 24V relays would fit.


how did you blow the relays ????

I don't want to add boards I want to replace the relays. However, those look quite similar. Maybe buying something like that would be a easier way to obtain the relays.

cheers,

I just built this kit for another project !
The relays are a few milimeters larger than the T1/T2 stock. They won't fit the board.

actually, maybe it's the power relay that's blown. This is the T1 V1.2 from the batch that had the faulty relays. Iv'e been running it under 24v and it has been fine up until last week.
