AD815 preamp PCB group buy thread

[hacker]

Looks like it may be a bit moot - the only 100n 0805 SMD cap I can see that goes as high as a 25V voltage rating is the C0G. The rest, including an ultra-low ESL (49pH) X7R cap are all rated at 16V which is too close to the supply rail voltage of 15V.

C0G should be fine, but I just wanted to squeeze the last drop out of the circuit.

Thanks,

Pete

Hi Pete, no email from you so far. Can you PM me instead please? Thanks.

FAO Stuart Frazer and Paul Russell: I've sent you guys email but it seems to be failing. Can you get in touch please?

Thanks, Carl.

Carl,

PM sent.

Thanks Pete

Yikes, Hi carl can I still go on this too? I think I put myself down on the orginal list but have probably changed emails and addresses a couple of times since. Id like 1 x pcb, 1 x chip, 1 x kit 3.

I can transfer to your account directly.

Ced, you have PM.

The group buy is now closed (with noted exceptions for a couple of people with clearing e-cheques, pending payments etc), no more orders please. I'll post expected turnaround times very shortly

[psymo]

Carl,

I assume you never got my email or pm, I guess its too late now anyway?

Regards, Pete

Hi Carl,
Hope you recieved my payment ok. I didn't bother sending an Email because of the problems you've been having.
Cheers

Guess what's on my table right now....





There's only one snafu that I can see at the moment, and that's to do with the trimmer pot for the DC nulling circuit. The PCB has holes for a trimmer with an offset middle leg, but the trimmers have perfectly straight legs. It's not a problem, because one leg is easily bent into shape:



Here's a bagged up kit4, one of the first off the press:



I'll have to get the rest sorted out, bagged up, checked, addressed etc... but we're on the home straight now

Cheers,
Carl

Excellent news Carl.

They look the business don't they.

Surprised you've not built one yet

Looking forward to getting my hands on these.

Thanks... but I'm going to wait until I know it works before I'm happy
