Adcom GFA-535 II power amplifier

Current Audio Projects: Jack converted two dual-mono Adcom GFA-535 II power amplifiers to mono blocks with dual-power supplies. He used an extra pair of outputs from spare modules and added them to each driver board similar to the GFA-545 II. He built the unit so that the output terminals are bridged for bi-wiring.
