Here are a few photos of the ELC Audio Engineering SEVT (Single-Ended Vacuum Tube) stereo power amplifier.

Figure 1.  Top view of SEVT amplifier.  Large cylindrical component in center is a filter choke / inductor.  Note the use of dual rectifier tubes.  Four of the ten tubes are voltage regulator tubes.  Very quiet and stable amplifier with minimal negative feedback.

Figure 2.  Front view of SEVT amplifier.

Figure 3.  Rear view shows 5-way binding posts, MIL-SPEC fuseholder, and jack for power cord.

Figure 4.  Underneath the chassis.  Low-noise film resistors and audiophile quality film capacitors used in signal path.  Electrolytic capacitors are only used for DC smoothing.
