Svart said:if you etch your boards and use minimal parts then you can build 1272s for about 150$ a channel.
Aren't transformers around $100 alone? Maybe a little more after shipping?

Per channel:
62$ input
28$ output
53$ for chassis/4=13.25$
22$ for toroid/4= 5.5$
That's 108.75$ for the expensive stuff.
That still leaves 42$ for pots, transistors, caps, resistors and a home etched PCB per channel(plus shipping). That's actually more than enough if you buy in bulk.
Now this doesn't account for a nice expensive front panel or meters or any fancy stuff.

Slenderchap said:There are price breaks at 25, 50 and 100 anyway (they are not shown in the store as it can only handle shipments weighing less than 7kg).... the base price is the 25 off price + 5%.... above 25 pieces you get the full benefit of the Carnhill OEM price.
VTB9045
1 - 24 pieces - GBP 39.18 each
25 - 49 pieces - GBP 37.31 each
50 - 99 pieces - GBP 35.61 each
100 + pieces - GBP 34.76 each
[All the real savings come between 1 and 25 pieces (the standard list price for a 1 off VTB9045 is GBP 119.01)]
It would probably make sense for small groups (eg Chicago area DIY group who will be meeting soon) to buy them together and then "hand them out" at the following meeting.... this way you benefit from bulk shipping and no further postal costs.... but you must factor in the import duties which are always applied by courier companies used for bulk shipping..... experience has shown that large Group Buys can sometimes be a lengthy and unsuccessful ordeal.... by keeping it small/local it would work quite well (I think).
