I need help describing the sound of a SET to a friend in English.

1930's table radio technology! I have four of them! Best used with speakers rated for 100db @1 watt. That means something like an Altec VOTT/A7 or the slightly smaller A5.

One of my single-end amps is the Golden Tube SE40. It uses three 6L6 beam tetrodes in parallel per channel. About 24 watts per channel. Rather a heavyweight among single-end tube amps! A lot more useful than the typical 2A3/300B amps! Plus the paralleled output stage gives it a much lower output impedance and consequently better damping/bass control. Am I the only one here that owns one? Production ended in the 90's.
