MAIN TRANSFORMERS, for high quality audio, GOSS C-CORE or Nano-crystalline:
Twin coil
Pri: 115VAC, 230VAC, 115VAC-115VAC.
50W, 100W, 150W, 200W, 300W, 400W, 500W @50Hz ( =+20% @60Hz )

Type 1:C-core, our standard range.
Type 2: Narrow freq 50-60Hz, high leakage ( For filtering out electrical noise from the main current and to avoid noise feedback to the main )
Type 3: low leakage ( For pulse and current signals )
Type 4:low EMI radiation.
Type 5: Low acoustic noise ( Nano-crystalline, low Magnetostriction )
Optional: Shielding 30dB, 60dB, 90dB, 120dB
