Cagey said:Tube rectifiers as applied in guitar amps are often current limiters, because the power supply generally isn't designed to deliver as much current as the amplifier section(s) may ask for. It costs too much money and makes possible a signal fidelity that isn't often required or even expected. As a result, if the amplifier asks for more current than is available, the voltage sags. This has an effect on the output which mainly manifests itself in the form of a frequency-dependent compression.
Huge fan of t00b rectifiers here; sag is groovy. :icon_thumright:
