Hi all,
To everyone interested in the alpha boards; we're standing at 50 pcbs. That puts the price at $8.56 each. I'll be placing the order tomorrow (Friday). Many thanks for the support guys. If you want in, then please hurry.

time to place the order.......
It's Friday morning and I've placed the pcb order. I ordered an additional 4 boards for anyone who reads these post late and didn't have time to place their order. Contact me if you're interested.

additional info
I talked with Doug at Mega Circuits recently. He described the pcbs as being off-white with black silk-screening. The solder mask on the trace side is blue. This should be an attractive looking board. The boards have all of the standard features we desire.
Here's a parts list with many of the part numbers. Look it over and correct me if you discover any errors.

Thanks
Thanks for all the good work!!
Can't wait till I get my boards and start building the beast.

Too late to order few boards?
Could someone who will be placing the next order contact me and let me know so I can get in on the next order.
I could use 2 or 4
Much thanks!

Brian ... I think it's not too late to get in on the rev1.0 boards http://WWW.DIYAUDIO.COM/forums/showthread.php?threadid=7385&perpage=15&pagenumber=4
Got a set of pair of boards reserved
I just sent John a email asking him to reserve me the last pair of boards.
Thanks to all

Hi Brian,
John may have already replied to you. You need to send the email to HiFiZen. See this thread.

Sometimes I have difficulty linking names to monikers......
Will E.W. Dailey please email me? Your funds have arrived and I'm trying to figure out who you are on my list. Also, I need a more legible mailing address from you.

info update
For those who are wondering.....
The pcbs have been etched and are awaiting the next phase of manufacturing. Also, most of the funds have arrived, thank you very much!
If I recall correctly, the finished pcbs will ship from the mfg. Dec. 10th, or there abouts.

both sides now......
I forgot to mention; if you install comp caps, do so to both sides of the circuit board. This is a twin configuration.

Hi folks,
Here's the latest email I received from Mega Circuits:

And there you have it, when I get the boards they'll be on their way; just in time for the holiday break.

They're in!
Finally!
They look good. I'll be sending them out this week.
Several small glitches:
First: I remember asking for plated through holes. The holes are not plated through. I don't have the original website take-off form from Mega Circuits to refer back to. I can't find this particular request in writing through any of my correspondence with them. I remember verbal communication over the phone, but if it's not in writing, then there's probably nothing I can do. I tried the holes against the components and they feel just snug enough for an excellent fit.
Second: there are a few small printing errors in the transistor labeling dept. The bases "B" on Q4 Q8 Q9 are mislabeled as "A". I checked the boards against my art and my art is correct. I'll be emailing Mega Circuits about this little problem. It won't be difficult to work around. Heck, it makes it easy to identify the first thirty amplifiers. 100 years from now, when they become vintage, this will be the identifying mark.
Third: the board color is green, not white. The silkscreening is black, I would have asked for white if I'd known that the boards were going to be this dark. The labeling is decent quality, just a bit hard to read against the green backing.
I don't mean to sound picky, guys. I'm a bit of a perfectionist and just want everyone to be pleased with their purchase. I believe these pcbs will work just fine.
Happy holidays,

Good Christ,
it took them six weeks to make these PCBs and they still managed to get something f'd up?
Who are these jokers?
The thru-hole plating especially it's a pretty big one.

Actually, I placed the order Friday, November 15th. The boards were completed around December 5th. Add the weekend and another four days for shipping and Mega Circuits arrives at approx. the three week projection. The first several weeks were necessary for gathering interest and offering pcb artwork for the group's approval.
The boards are nice looking. They are of similar in quality to BrianGT's Aleph Clone pcbs, a little thinner though with black ink instead of white. The component holes are tight fitting, so there shouldn't be a problem with component leads making contact with the pads. The soldering pads are a bit larger than Brian's and should make soldering rather easy. If I had a digital camera, I'd offer everyone a snapshot.
I'm not displeased with these boards, just picky by nature.

Beating a dead horse.......
Ok, I got a reply from the supplier: Since I sent them single sided artwork, they manufactured single sided pcbs for this order. According to Doug, the salesman, I would have had to order double sided boards for plated through holes with $3.50/board in added expense. Now, this misunderstanding never seemed to be a problem with ECD and I never guessed that it would be a problem with Mega Circuits either.
Also, double sided pcbs have solder mask on both sides (our pcbs have the mask on the trace side) and the silk screening color is automatically white. Hummmmm. I wonder why I was told that the board color was off-white?
My apologies go out to anyone who feels that I let them down.

Thanks for putting in so much time. Things don't always come out exactly the way you want. I am sure it will sound great.

I'm willing to bet that my brother will think the amp I give him for his 50th sounds marvellous and I'll be sure to tell him the boards are FAMOUS! Thanks for your efforts.
