depends on what voltages you need. What are the specifications of the channel strips?

Many thanks, Weiss!

The two channel strips require +18v, -18v, 12v for a relay and an LED, and 48v for phantom. Cyril Jones of Raindirk suggests that I tap-off the 12v using a zener diode.

Do you know what the current draw will be for those strips?

 

[Terry McInturff]

Apparently 1A per module will be plenty.

iirc. Lm317 has something like 1.5A max current(if that kit uses those?)
Anyways that 1 amp/strip sounds quite big for a preamp?

Any suggestions for the right transformer for my kit please folks?

You have all the information to work it out for yourself Terry. After all it is DIY. Look up the regulator chips you are using and work out how much voltage you need above the rail voltage (18v). You have said 1 amp is enough current (seems high to me).
Away you go!
