Just trade places you mean?

Yes, like in the movie.

 

[42001]

That worked!!!!

Now that side is 0.3MV !!!!!!!

 

[42001]

Love that movie!

 

[Salas]

You get lucky in real life too.

 

[42001]

0.3 and 0.6 MV

Nailed it!!!! Thanks Salas!!!!

 

[Salas]

You are welcome. You can use it in the stereo system without fear now. Let us know how you liked it. A finished photo will be welcome too.

Lights

Some pictures.... The finished result will follow when done

 

[Salas]

Making and integrated amp? What will be the power stage?

 

[42001]

No, not integrated. Just use the softstart to drive the push button and LED in the button.

The very small PSU is to match the brightness of the leds in the front panel(selector switch) to the led in the power switch.
The case was chosen to match the one of the power amp.

I built a Hiraga 20Watt Class A. So this baby will drive that amp.

PS: DCB1 is on for 15 minutes now and offset is 0.4MV on both sides.....

Using horn loudspeakers?

 

[42001]

No, electrostats. Very, very transparent sound.

They are kind of home made: Final 400 panels with adapted PIO PSU's.

And a subwoofer for the low frequencies. That sub is why I probably will put two diamond buffers in from Sjostrom. I do not want to lose too much signal.

Finished DCB1

Almost finished It's making music right now and it sounds nice!!!!

 

[Salas]

Very good. Congrats.

 

[42001]

And here they are together

Both DCB1 and Hiraga making beautifull tunes:

Question, it seemed that the B1 was a bit warmer in sound. Could that be the difference in resistors? I now used the BOM resistors from Takman, and the B1 was populated with Kiwame's. Anyone have any ideas on this?

 

[stajo]

Resistors of course. Even more pot and eventual output capacitor on the B1. And burn in time.

 

[Salas]

Looking nice in those boxes as a combo. The coupling capacitors are missing so its more direct sound. Could be telling more about the source & system. Taking it up to 200mA with some small sinks could give more fleshy tone. The four 220R could be exchanged on type preference. Some use Z-foils or wire-wound Miniohms as ref neutral components there. But expensive. Let the lytics completely form out with some playing hours as Stajo said nonetheless.

 

[42001]

Changed the pot from 50k log stepped Khozmo to a 25k log pot from TKD, the 2511. The Khozmo was noisy when changing the volume....


How do I go to 200Ma??

 

[WalterW]

Hahaha, by reading all the threads, like I did
