  1. Tons of circuit online http://www.seekic.com/circuit_diagram/Electrical_Equipment_Circuit/Improved_lamp_dimmer.html http://www.seekic.com/circuit_diagram/Electrical_Equipment_Circuit/Low_cost_lamp_dimmer.html and so on Don't go and kill your self :)
  2. Ahh yes, thankx - Peak power :) Ok, but the 81VAC (600W ish 8R) still seems high to me, as it says 300W RMS 8R on the back, and the external speaker is parallel connected to the internal speaker...
  3. I'm repairing a chinese amplifier for a subwoofer and don't get it The amp powers the internal speaker and you can connect (in parallel) an 8 ohm 300W sub. So I assumed that the amp would give 600W(ish) in 4 ohm, so that the marking on the bok fits (8 ohn 300W external sub) But the capacitors witch is faulty was 100V (all of them blown), the transformer gives 81V-0-81V witch is about +/- 115V - should be enough to 1500W or there about? or am I completely wrong?
