 Sci Advisor P: 4,032 I see Radio Shack have these transformers: Model: 273-1512 | Catalog #: 273-1512 Which sound like they would be suitable. $10.49 is a fair price. They also have these capacitors: Model: 272-1047 | Catalog #: 272-1047 for$2.59 They are not "LOW ESR" but may be OK to try. If they get hot, you might have to get the good ones. And they have these bridge rectifiers: Model: 276-1185 | Catalog #: 276-1185 for \$3.29 Oddly, they don't seem to have 390 ohm 1/2 watt resistors although they do have 330 ohm ones which would be OK if you couldn't get anything else. I have a flashlight with 19 LEDs in it and this can light up our whole back yard. I wonder if you have low output LEDs and might do better with higher output ones?
