Thank you I'll look into that. At the very least I could learn how to use eagle and redraw it.

Let's cut to the chase. If you download the files for the PPAv2, you can easily shave off 1cm from the top (or from the bottom if you wire the pots offboard). Then, you can order from the links given by wakibaki. For example at Itead Studio, 5 pieces of the same 10x15cm pcb are only 45$ + shipping. 9$ a piece thus and you can easily find other diyers to share some of the costs I guess. Seed has similar pricing. The PPA is all through hole and is a piece of cake to manufacture, so there shouldn't be any problems.

 

Thank you for this. In fact I bet I could get some interest in a super hq headamp locally and just build the other boards and sell it...then I might even have enough money for another amp ;)

I think you can order the low volume PCB fabrications from China,because the price is reasonable and the quality is good too. such as wonderful PCB and PCB cart is a good choice.Hope can help you

In spite of all of this, I want better :) I saw the article about the PPA v2 amplifier on Tangent's site and aimed for this to be my ultimate project. Unfortunately this project requires 2 PCBs to be custom fabbed and it seemed that the cheapest I could get this on ExpressPCB was around $150 (2 boards of different designs not 2 of the same one [batt board and amp board]) this didnt seem right....The main cost to me seemed that it should be the IC components...not the board itself.

 

So to get to the point of this post if anyone has experience with custom PCBs and knows where I can get single boards cheaply please let me know (I would preferably want a fab that could turn it around in less than a month)

I would preferably want a fab that could turn it around in less than a month---you mean it will take you a nearly month from the order you made to the time you got that boards? Then it is really toooooo long. In fact, for simple boards with with small quantity, 3-4 days is ok, after 3-5 days shipping, then it will be going to your hands. two boards, if it is less than 5*5cm, 5pcs each, i think $80 could be ok, the shipping cost usually about $30, so totally about $110 with 10 days to your hands.
