This pair of Dynaco Mark III monoblocks were completely disassembled and transformers resprayed. New driver boards from Vacuum Tube Audio were installed to mod the circuit. Speaker connections and bias test points were replaced with more modern setup, along with a new power switch and input jack. The new circuit design allows for individual biasing of the power tubes, along with dual 6SN7 driver tubes. Slow start fusistors were added before the power fuse to allow the unit to come up to voltage slightly slower and suppress surge which plagues the filter caps on these amplifiers. The results of the heavy modifications is outstanding and these are a pleasure to listen to.
