    I understand that Twin Reverbs use SS rectifiers and Deluxe Reverbs use tube rectifiers.

    What are the advantages/disadvantages of one over the other?

    In addition, amps with solid state rectifiers seem to react faster to your input than tube type. Also, while solid state rectifiers can generally tighten up the bass response of an amp, they can also make the top end harsh. These are just general observations....different power supply filtering schemes also come into play too. Bottom line is there's no right or wrong....but what sounds/feels best to you.

    Thanks for your knowledgable responses.

    Now this... Is replacing the ss rectifier on a Twin Reverb a common or desirable mod?

    You would have to cut the chassis to fit more tube sockets. I don't think a single rectifier tube would handle that power. I think you would need two.

    Short answer...NO.

    Nor mine. However, I wonder why they used a tube rectifier in the Deluxe Reverb.
