The Conductor preamplifier (E88CC CCa/6N23Ps)
The Conductor preamplifier (E88CC CCa/6N23Ps)
Super-Fi The Conductor is a tube line preamplifier intended for stereo hi-fi systems where clean, stable and dynamic volume control is a priority. Designed around the E88CC/CCa/6N23P dual-triode, it is ideal for integration with tube or transistor output amplifiers. Top hi-end device.
Technical characteristics
- Tube assembly: E88CC / CCa / 6N23P (also compatible with 6922/6DJ8 family)
- Gain factor (line stage): typically 6–20 dB (depending on installed tubes and operating point)
- Input impedance: high, typ. 50–100 kΩ; Output impedance: low, typ. 100–600 Ω
- Frequency range: ~10 Hz – 50/60 kHz (−1 dB), flat transfer characteristic in the audio range
- THD: typically 0.05–0.3% at 2 Vrms output (even harmonics dominant)
- Or. signal/noise (A‑weighted): typically 90–100 dB with quality tubes and proper grounding
- Nominal output level: 2 Vrms (max. higher depending on power supply and gain)
- Connections: line inputs/outputs RCA (single‑ended)
- Power supply: linear, with high-capacity filtration (suppression of hum and network noise)
Sound characteristics
The sound signature is neutral with a slight tube "glow" effect: clean midrange, precise stereo scene and natural vocal texture. Low output impedance contributes to tight control of the bass range, while micro-detail remains preserved without harshness in the highs. Dynamics are linear, with stable channel balance at low volume levels.
Condition and maintenance
Like new, excellent condition - functionally correct, no noticeable noise or microphonics under normal operating conditions.
