    Review:
    Works like a charm and not that hard to assemble. I got two kits for two tube preamp builds. Output voltage range is more like 90 to 290 V. Higher voltage is never a bad thing in tube circuits, though.\r\nThere\'s an easy mod to increase output voltage even further: Change R4 from 470 to 390 ohms. Gives up to 355 V on light loads.
