OK everybody, repeat after me...

Get a Power-One Model number HAA15 - 0.8 - A from about a zillion places (Allied, Newark, Sterling...). They
are about $42. I just bought 25 for the MOTM kits. Strappable for +-12 or +-15. UL/CE/VDE approved.

I am in need of a +- 15volt DC power supply. I will be using it to power
the ASM1 kit from G. Stopp. I have toyed with several possible ideas.

A . I could get an unregulated DC wall wart supply and build a regulator
curcuit. This appears to be the way the PAIA fatman and MIDI2CV is done.

B. I could build the whole thing (i.e. Transformer, Bridge, caps, regulator
etc) from scratch.

C. I could buy one. (Found one for $60 u.s. at electronix express)

I am concerned because I understand that the ASM1 needs a very stable and
well regulated power supply. 

Does anyone have a schematic for a good supply they could FAX me or email
me as a graphic? I hate that ascii art stuff as it is kinda hard to read.
