Default My new 8 channel home Cinema amplifer "sure" 8x100WATT - TK2050AMP

Hello,

Just for fun - today I finished my new sure tripath 8 Channel power amplifer.

Click the image to open in full size.

I own since 2006 a yamaha RX-V2600 receiver.


My plan is to use the RX-V2600 further as pre-amplifer/processer.

My oppo BDP95 blu ray Player sound so amazing in this combintion. As test I connenct the oppo direct to my new tripath 8 ch power amp.

Wow - my 6 Infinity Beta 50s + beta c360 never sounds so "live" & power driven.

My beta subwoofer SW-12 was complety off for the test.

At first I remove the heatsink and adjust the DC-offset. From the factory came my two 4x100 boards with realy horrible values. All eight channels has values around 100mV to 300mV DC.

After I adjust the offset - all 8 channels have values from 2mV to 7mV (after 30 min. warmup).

Then I order a "blank" case for my setup - and do some work out. Drill holes, place feeds - complete the electronic parts......

Regards, Ronald

One 4x100w board and one 2x100w board, and a smps of suitable power. Im pretty sure sure electronics have everything you need, the chassis can be had from places like antek on ebay or modusshop or whatever the name was, or if you feel up to it, you could bend up some sheet metal yourself.

Hello,

thank you! Yes it looks not only great - it sounds great too.

No "bass" hole or other issues in the sound spectrum.

I bought two of this new sure units --> 4x100Watt

The look very clean and professional. Only the DC offset was not perfect....up to 300mV.


Ok, I order my case from --> audiophonics


Regards, Ronald :-)
