God ! 😕🙁 Now I am afraid to buy your amps ! I can hear what kind of resistor I use both from the inverting input as well as the feedback resistor !

No, the opamp's inverting input ties to the output, so the result is an extremely stable circuit. The most dangerous opamp environment is one or both inputs open. Edit: this assumes voltage inputs, not a BJT opamp.

Bruno, when you're done with that preamp article and you find yourself with too much free time 🙂p), I believe that an "I/V stage for 9018 based DACs" article would be very welcome.
I'm sure Jan will be happy to publish it and many of us will be more than happy to build it. Just saying, no rush, we can all wait say... a couple of months. 😀

Me too. But on the positive side, the power amp should be really great if it still sounds good with such a crappy pre 🙂
Every day this week I have rushed home excited to check my email and hope to find a shipping confirmation 🙁 Maybe tomorrow will be the glorious day?
Yes so do I . Every day I check my account. Still just " pending " waiting for "dispatched" .😀
Same here. I had hoped to receive them on my birthday (16-3) but I'm afraid that will not happen...🙁
Just be patient and you will be rewarded.
Two of my friends now both want a hypex amp too after hearing mine. The thing I find very enjoying is that they are both tube adepts. LOL!

Careful there boyo. That was Bruno, a very wonderful dog who lived with my friend Ian.
It was supposed to be a local rag for the group of guys that hung out and played with audio here in town. A little homage to RCA was fun. It kinda got hijacked by a more ambitious editor.
I was the first technical editor of PF. I am no longer (and haven't been for a long time) affiliated with the organization.
By the way, you are *supposed* to discuss about this stuff, that's the point. (preferably with a pint in hand)

The Hypex shop server seems to be having issues - everyone eagerly checking their order status?
My order status is pending. Hope I'll get from this batch.
I payed by bank transfer and I never got a confirmation that Hypex had received the payment. That something that would have been nice to receive.

My order status shows "pending" on their site, but I never received any emails from them other than through my Paypal account for the debit activity. Hypex said yesterday that they are working through the orders and mine should hopefully ship next week.
If you see that order status is ' pending' then we have received the payment by bank, Paypal or credit card.
Indeed production is working hard to get the modules ready for shipping....
I have a question. I've been looking at the NC400 data sheet.
For XLR wiring I'm missing something. It shows what the pinout is on the NC400.
There are four color wires.
Red
Black
Yellow
Silver
As for pinout on the XLR is it:
Pin 2 Red
Chassis Black
Yellow?
Silver?

Well, the actual pins on the J9 connector are more important than the colors, but on the cables I have the colors are:
Pin 1 - INH - Red
Pin 2 - INC - Clear
Pin 3 - nAMPON - Black
Pin 4 - Ground - Yellow
INH and INC (Red and Clear) go to the signals pins on the XLR - pins 2 and 3. Yellow is ground, and goes to pin 1/chassis. The black one, nAMPON, is for turning the amp on by connecting it to ground - so no need to bring it to the XLR at all.
