Hi, does anybody can tell me where to get the relays (-100).
This type seems to be the better one, but i can't find them.

regards Michael

Both relays specified on the BOM are named as -100. You can get both 12v and 5v from mouser and farnell.
For the 12v one you have parts number 653-G6H-2-100DC12 from mouser and 9949208 from farnell.

I needed 16.
Bought 20 through Ebay. 4 were faulty, 16 were good. Partial refund from HK came through OK.
About 1/3 price of buying locally.

Hi,
the -100 type is more expensive, yet I have not found a hint from manufacturer, ift is definitely better. Has anybody else? What is the difference?
Reichelt supplies the "not -100" part. But you might know this.

Cheers Ernst

OK. High reliability means, it works under harder conditions or longer under equal conditions. But does that mean, there is any influence in the contact quality, finally in sound quality?

I suppose it will be both. Components stress makes them to have a shorter life.

For example, a capacitor that will be applied 35v. You could use one rated to 35v or to 50v. The 50v one both will last longer or can work under harder conditions (until theorically 50v)

Default It's alive! It's alive!

As some of you have suggested, I have upped the default CCS. It does heat the heatsinks quite enought to feel the desire to lift your finger after 10 secs But i don't think they are HOT, after all they are power mosfets prepared to deal with higher temps than my finger. The hottest ones are the ones closer to the relay.

In the CCS resistor (R1), I recommend to put a 2W resistor at least, it get quite hot with that. Better 3w or 4W. Between 9 and 10 Ohm its OK.
I have put in series two 2W resistors achieving a total of 9.6 Ohm. One drops 2.178v, wich means 226mA. The other one drops 1.965 wich means 204mA.

Offsets are -0.82 and -1.54 with inputs shorted. No AC at the output with inputs shorted, wich means no noise at all.

I haven't yet hooked it up to my speakers, so I will listen and tell you later. Here are some pictures I've just taken. Enjoy them.

And try this mod, it works.
