Output Transformers and Impedance Matching Explained
How an output transformer matches high plate impedance to a low speaker load, why a mismatch or open circuit is dangerous, and what 'minimum load' protects.
Why Reactive Loads Sound Different From Real Cabinets
How speaker impedance becomes frequency response through amp output impedance, why reactive loads don't feel like a cab, and the IR double-count trap.
The Ultimate Hot Rod Deluxe Mod
Fix the Hot Rod Deluxe's PCB-cooking dropping resistors, then rework the power amp and preamp for a blackface-style feel and usable drive channels.
