Manleys amps were made the same way. When I had a pair of Neoclassic 250s, a tube took out a resistor. Manley would send you out the resistors with pre-soldered clips on them so you didn’t have to send it in. You took out the old resistor leaving the stems soldered to the board, and clipped on the new resistor.
Worked like a charm. Perhaps ARC does something similar?
