I am building a simple pedal board consisting of one TS-9 Tube Screamer and one AD-80 Analog Delay. The TS-9 requires 9VDC while the AD-80 requires 18VDC. My wall voltage is 120VAC and I would like to build a single power supply box to feed both pedals. What is the best way to accomplish this?
I am thinking about using a Hammond 164H20 (115VAC to 20V CT @ 1A), then full wave rectifier, big filter cap, then split to a 7818 and 7809.
A few years ago, I successfully built a simple regulated power supply with three parallel 9VDC outlets. It works great with my Boss pedals. Need something for these Ibanez guys now : )
What's the best way to get 9V and 18V from one box?
Hmmm... should I wire the 'bottom' end of the secondary as 'common' and use both secondary 'halves' into rectifier/filter cap for the 7818... then use center tap to feed a second rectifier/filter cap set for the 7809? Perhaps this scheme would be a little easier on the regulators.
