DIY

MEC-50 and MEC-100 come as potted and tested modules. It is intended for either upgrade of existing tube amplifiers, or building new. OEM customers, please apply for more info.

General Description

Designers Menno Vanderveen and Guido Tent decided for these designs after the positive reception of the E-choke, 2 yars ago. MECs typically fill the gap towards smaller power amplifiers (100mA) and preamplifiers (50mA) where the E-choke was still to big.

MECs replace traditional chokes that generally work quite well, but suffer from serious disadvantages:
• high weight
• relatively big size
• magnetic field radiation that induces hum in the circuit

The MECs effectively solve all these issues, and offer up to 60dB supply ripple reduction
