The SE300B supplies a power of 10W RMS and functions in pure class-A with single-ended mounting (the two tubes are in parallel) with an automatic bias. The two high voltages, driver and power, have vacuum-tube power supplies. The bandwidth (at –3dB) is from 20Hz to 20kHz, without any feedback.

I300 is built around a simple 300B push-pull without feedback which offers unequalled musiciality of this tube. After the preamplification using an ECC82, the signal feeds a phase inverter (called Schmitt) followed by 6SN7 triodes sufficient to drive the 300B.
