101 R2 Zero Feedback Pre Amp Module

$232.00 $365.00

Holton 101 R2 Zero Feedback Mono Bloc Pre-Amplifier Fully Assembled and Tested

Two Pre-Amplifier Boards needed for Stereo.

Holton Audio will be releasing a new fully discrete Full Class A MOSFET Pre-Amplifier (No Opamps) with selectable feedback topology that will enable the user to switch the feedback mode of both channels from the front panel and 3 modes of operation will be available. The 3 modes of operation will be Zero Feedback on the MOSFET Output Stage; 50% Feedback on Output Stage and Full Global Feedback for entire amplifier circuit.

It will have is own fully discrete low noise low drop out regulated power supply on board and each main board is arranged in full mono block design, so two boards are required for stereo.
