a link for DCB1 ? i am not i found the correct one
DCB1
This would be the one!
BTW I also received TK2050 V1.1B and I must say it sounds great also the positioning of the elements and some extra holes are very welcome, so you can pass the potentiometer(I saw those holes when I removed the pot
). I will post some pics of my implementation.Regards Aleš
I recieved the T3 today and hooked it up with a 400w 48V SMPS, it works like a charm.
Compared to my Yamaha AV reciever it's just like getting a brand new set of ears The clarity, the details in the music is so much better.
I can hear some very low noise from the speakers when volume is turned down but this could be related to that cables are lying in a mess around the boards right now, couldn't wait to hook them up.
Next thing is to get a case for them.

Sometimes the simple things are difficult! I was eager and in a hurry to try the T3, but realized I didn't have a vol pot, and needed to connect my dac to two T3 monos.. That made me make some of these cables and pots to make it easier to connect to two t3 monos. Not everyone will have a need for this, but for some it could come handy. I got a guy to make 100 of dual output cables from one 3p connector, and hifimediy supplies pcb's with either ctr or alps pot.

Greetings friends,
I am trying to put everything in a case right now, finished it this morning and measured everything before switching it on, everything looked ok.
Switch on, then after around 25 sec the green led lights for few sec and then goes off again, then on again, etc.
Measured 26.8 VDC input on board.
When music was here, it looked/heared perfect.
Do you have any idea ?
(by the way the 25 first seconds seems very long)
Thank you

Hi,
what's your yamaha model's ? For the comparaison with my RX-V2700...
thanks
Hello Nick,
Just tried with nothing else than 26.8 VDC and it remains the same.
Board looks perfect, music looked perfect when I had it.
[Edit] Just tried 29.6 VDC with the Meanwell-350-27 : the same
.[Edit] Just switched DC inputs : the same.
Regards,

Measure volts
Measure volts where the dc comes into the board to see what it is doing.

Just measured :
The input DC remains stable at 29.6 VDC whether the relays are ON or OFF.
Any other idea ?
Thank you.
Offset
Measure the dc between each pair of speaker outputs one at a time, preferably before the relays. Can you touch the output of the coils for the measurement?

1st try :
Measured output VDC directly into the speaker terminals, without any speaker connected and without input audio signal.
Both pairs : oscillating between 40 and 200 mV : normal ?
With a screwdriver ?sendler said:
with speakers
With speakers connected and the amp warmed up, you should be able to adjust the dc offset to stay steady within 5mv of zero.

Let's summary :
- v2 amp is in metal case
- output offset both pairs set to 1mV
- Music flies cool ... when music is here
The problem remains : the relays do "clac" sometimes, anytime ... sometimes 10 times in a minute, sometimes not for 5 minutes.
Do you have other ideas about the problem ?
Listening to music is a pleasure, with the fear of the "clac"
Thank you all,
