Bipolar Variable Power supply for protoboard - Page 2

Hi,

the power supply i am developing or a simpler version would more than cover your needs.

LT Dual Tracking 3A Regulated Power Supply 1.25V to 20V

the adjustment of a single trim pot sets both the positive and negative rail voltage. If you don't want/require the higher performance that the lm329b offers it is dead simple build. You also don't need to use LT1033/LT1085 regs, just about any adjustable regulator will do.

also, i will order prototype boards in the next couple of weeks and once i determine the cost i would be willing to sell you one. they won't be as cheap as typical offerings around here because i am ordering so few boards (i had only planned on personal use) but let me know if you are interested.

lastly, twisted pear audio has a few PSs that may suit your needs and the price is quite good.

good luck
