Most of the earlier amps used valve rectifiers which introduce that same sag feel, exept they do it for the power valves too, so it has an even greater effect/affect (never sure which, so there's both!!).
Valve rectifiers have an internal resistance, using around 100/200 ohms depending on the type, and drop voltage proportional to the current drawn just the same.
If the vintage amps had used a power resistor choke and a vlave rectifier the amp would have sagged like old ladies boobs!!
