Exclamation Tube-I-zator modifications

Hi to all,

today i received the rest of the parts to complete the Tube-I-zator PCB.
Now i am ready with soldering and everything work fine.

Click the image to open in full size.

Nevertheless i must give two necessary information to you.

Click the image to open in full size.

1. Because of a missing ground line, please add a small wire as on the picture.

2. Both relais must be soldered to the bottom of the PCB. These relais have a polarisation and work
only on the bottom side. (Polarity failure in my PCB design program)

Please apologize these two points. I hope nobody is enraged about that.


Best regards,
Oliver

Hi, do you have an alternate part for the Panasonic Relay? Mouser and Digikey do not carry them any more.

You could also use the standard DS4E-M-DC5V version.

It has only the double operating power (400mW each).

How does it sound compared to passive I/V resistor output? (say from TDA1543 dac)

Hi Fran,

Thanks. The guy in the link uses no I/V resistor saying he prefers the sound, but you do have a I/V resistor. Have you tried it both ways? I as thinking of this board for the output of my DDDac (tda1543 x 24 stacked).

If you want it for Doedes DDDAC i think you should get his advice, too.
I for myself use a TDA1541A with a I/V resistor from Texas Components.
