MCoil BT · Baked Varnish

Our transformer-core coils combine both lowest distortion rate and precise pulse signal with low internal resistance. even under highest output levels. Therefore they have been the benchmark for extremely precise and powerful but deep bass performance for more than 25 years!

We are very pleased to present a completely revised and expanded model series. now meeting frequent customer requests for smaller dimensions. too.

The outstanding features of this series can be considerably enhanced yet by the appliance of Baked Wiring Treatment or Vacuum Impregnation.
