2x60W/1x120W audio amplifier PCB (LM4780/4732)

Raikkonen,

You don't need this 56pF capacitors in most applications 😉 Those are additional components. If there is an capacitor in signal path you also don't need C1 and C2 (47-100uF) so place jumper.

I received new board - this is a relay volume control (130 steps: -56dB to 0dB). I hope that I will find some time for it...

An externally hosted image should be here but it was not working when we last tested it.


O, and this is my USB DAC - like I said you will find PCB for it in this last (delayed) sets 🙂

Hi,

I received my parts about 3 weeks ago. Everything was OK, I also got one of those DAC Boards(thank u Damien🙂 )

But Veteran seems to be very busy, it's very hard to contact him indeed...

Anybody tried out that DAC?
Whould be nice for Notebooks...
But there are some exotic regulators wich seem to be hard to get...
Any Idea what sound quality is to be expected from the PCM2702?

I'm sure there's a good explanation why Damian is not around for the time being. I have had no reason what so ever to doubt his honesty. Got my boards and ic's in a few days after payment went through.
And i must say Damian was a very patient guy, i had a lot of trouble getting my account right at Moneybookers, and he guided me all the way 🙂

I just hope the explanation is not ilness or worse things

Best regards
Ebbe
 
That is all very well, especially as you've received your order. However my payment went through on 16 july and i've not even received an acknowledgement.
I have contacted moneybookers to report this as internet theft.
Unfortunately our federal police don't have much to do with the polakistani police, so my complaint will go nowhere.
 
Hi,

Yes, i've checked the post office. I work from home so am always in to take deliveries, we're also very friendly with the postman so if i'm not in he leaves packages in my garage.

Veteran did reply to my first email (after he was away on a conference or similiar), and said he had not been home to see if any deliveries were returned yet, so would get back to me. Infact he did not know what method I used to pay him even though I sent a confirmation and at the time of payment he sent me an email to say he had received it. Which leads me to believe he was a little unorganised with the group buy and perhaps "forgot" a few people.

I was a bit concerned at the time about the low postage cost, when ordering more than just a few boards $5 if-it-gets-there-you're-lucky postage method doesn't really cut it.

I'm fairly new to this forum and so far I have done this group buy, and bought a projector filament from 18wheeler's (a member in this forum) website, after being recommended to do so. He has now gone missing for about 60 days and i've had to open a dispute with paypal.

Obviously I must be fairly unlucky, and i've now lost all faith in what I first thought was a great hobby forum.
