Default aleph2 boards from kristijan

i have a few aleph2 boards for sale...

i have 6 full sized boards. these are the older ones the kristijan used to sell that has all the fets on a single long board. its around 11.75" x 4". 4 of them are almost fully populated. they are only missing the fets (see my other post for fets), zeners, and IRF9610's. otherwise, they are fully populated. they have black gate caps and dale/vishay resistors throughout. all resistors were tested within 0.1%. the other two boards are the same but dont have the black gate caps, they dont have anything there. but they have resistors, and a couple of the small value caps. you would need zeners, fets, irf9610's, and electrolytic caps.

THEN, i have two aleph 2 boards that are the traditional type. they are the ones that are currently on kristijans website. these are fully populated. they also have black gates, dale/vishay resistors. they have zeners and irf9610's mounted (matched) with heatsinks. the gain and constant current boards are fully assembled as well, including all the fets you need. i havent tested them because i didnt have a proper heatsink, but its assumed as working (as good as any DIY project is). i dont KNOW if there is anything wrong with it, i assume its all correct. i didnt use bad parts or anything. but i would highly suggest checking it out first.

here is the schematic and link for the boards:

http://www.kk-pcb.com/aleph-2.html

this really only applies to the last two. the first 6 have a different layout and are all on one board. he is charging ~$64 for a single channel. the first 6 boards are all single channel boards. the last 2 are single channels, but 3 boards total. so, i have a total of 8 channels of aleph2 power

im not sure of prices, but keep it reasonable please. consider the cost of the PCB's ($64 per channel) and the fact they are stuffed for the most part. just tracking down parts can be bothersome. and the last two boards are finished, they just need a power supply. if you have any questions, let me know. thanks!

i still have 4 of the single channel (big) boards left. ive been told they can be used for single channels of aleph5's. you could probably do an aleph3 with them too. any reasonable offer will be accepted, i just need them gone, i have NO need for them.
