Hey all, I just stumbled upon these amps...does anybody have a "finished" (doesn't have to be pretty) picture I can look at? I just want to see what type of connections are needed after I receive the amp and power supply. Thanks.
Tjeck the page before this for an image of a finished amp

See thread 462 for an owner's manual for the V2 (what became the T2). It has a photo labelling the hookups. I am sure Nick, who posted that thread and runs the retail side of hifmediy can direct you to more info about their other products.

Is there something that detailed for the T1? I recently ordered a T1 bundle and would not mind looking at a schematic.
I already have some T4 boards now and you can contact Nick for more detail. And thanks for your support
Hi, I made some kinds of potentiometer and some of them are ready, some of them controlled with IR, but I don't have VFD project now, may be later.
I wonder how the sound of a sta517B-based amp differs from one with sta510A?
I thinks T1 through T4 are similar except power. hope you like them all
Thanks for your vote. And the news is I just tested the switch function and it works good. So I will start T4e( an extend module or board that can be connect to T4 to accept digital inputs) soon.
1.5V is determined by TC2000. And all amps have their full power sensitivity. Don't be very care about this parameter and you also can use a pot or attenuator if necessary.
Hi, pls check what cause the relays to turn off, output DC or HMUTE problem first. Or try to find if there is bad solder on board, like sta505 IC etc.
As I said to Steinar few months ago I had (and still have, but rarely) the same problem with my T2 :
When switching everything on, the relays do click on and off and on, etc. again and again.
Sometimes just 2 or 3 times, sometimes for 10 min.
Sometimes everything's working fine for one week ...
I didn't find the reason.
Regards,

Regards,
My output terminals were poorly fastened. That seems to have been causing the issue. DC offset was fine and I was able to adjust it down to near 0 mV. Maybe tonight I'll secure everything back inside the chassis and hopefully be done...
Whew. I hope it was all just a bonehead-invoked problem.

Well that was wishful thinking. The clicking has stopped altogether. Now I can't get the relays to engage. Green LED doesn't come on, and naturally I can't measure DC offset at the terminals.
Very discouraged.
More data points: one of the four output coils gets really hot, while the others are much cooler; the SMPS is putting out a steady 31.5 VDC; I can hear a very high frequency whine directly from the module; red LED is on, with no flickering.
I certainly don't have the skill to figure this out. I'll probably need someone else to take a look at it.

Sounds your relay does not engage due to amp protection.Well that was wishful thinking. The clicking has stopped altogether. Now I can't get the relays to engage. Green LED doesn't come on, and naturally I can't measure DC offset at the terminals.

May I suggest that you lower the SMPS to 30V (31.5 is above specs for T2), recheck the input connexions, and recheck the output terminals : no connection at all to ground/chassis here.
Also, check solder on the coils. There were reports on issues due to coils not properly soldered. Maybe damaged during transport. Check all solder
As you say it worked before you put it on a chassis.
So maybe you have accidentally shorted connections.
Check speaker and power connectors.
