Apex A40 amplifier PCB interest check

[pinnocchio]

I'm running a batch of Apex A40 PCBs rev. 1.4 (PCB layout by Alex_mm).

I'm planning on ordering a batch of 10 or 20 of the following specs

2mm thickness
2 layers
Gold immersion
1oz copper (for 20 PCBs it will be 2oz)
white solder mask
black silk screen

PCBs are 194mm x 94mm

Support for this amplifier can be found on this thread :
http://www.diyaudio.com/forums/solid-state/164093-100w-ultimate-fidelity-amplifier-902.html

A would sell with shipping included for 26$ usd a stereo set. Keep in mind that these PCBs a large so production cost is relative to the size. I only have 4 sets to sell as I'm keeping one for myself.

For 20 PCBs if the demand is there, with 2oz copper instead of 1oz copper, the cost per stereo set including shipping would be 22$. So the aim is to get to 20 PCBs which 8 sets would be available.

Keep in mind that I'm covering for 10$ shipping, if it is more expensive for your country, I will charge the difference.

Thanks

Do,
You've have build the A40 yourself?

Hi meanman1964,

The goal is to build it for the first time. Alex_mm who sent me the gerbers told me he had built it and really liked it. Mile from Apex wrote that the A40 along with the P30zf preamplifier were the best Apex. So I was curious and decided to try it. I have a few P30zf PCB at home that I just récrivez as well.

I like nice quality PCB so that's why I'm going with this quality but I could go with only 1oz copper since the traces are pretty thick.

Thanks
Do

Perhaps a link to the thread will help the potential participants. Your price for a stereo set of nice PCB is actually quite good., IMHO.

 

[miro1360]

what is your charge for shipping into Slovakia (EU), still price 26USD with shipping / 1set?

Hi,

So far I've got the following people interested in the PCBs. There's room for two more sets.

bfg4wd
meanman1964
mlloyd1
pchw
mos
asuslover

@ asuslover, you can use speaker protection found on eBay, Mirand audio also has a very good one, Apex has some in their thread but Prasi has made one available which is also an Apex design. You can find it here:

Thanks

[pinnocchio]

I just sent a PM to Alex_mm requesting for modified gerbers since I want plated through holes everywhere, top solder mask as well.

 

[pinnocchio]

For those interested, I also have the P30zf preamplifier that Apex said was best of their designs. These I already have the PCBs at home. White solder mask with black silkscreen.

I have 5 sets in total but 3 already spoken for. 2 left... 10$ usd a set plus shipping but if you're already buying the A40, I will simply adjust shipping according to weight.

Thanks
Do

Count me in for stereo set.

 

[Kay Pirinha]

Hi Pinnochio,your effort is well appreciated!I'd be interested in a stereo set of PCBs for the A40 and for the complete preamp as well. Would you please tell me the shipping fees to Germany?Best regards!

 

[Junie]

Do, include mine with preamp as well. Thanks.
