SOMBETZKI S 509 tube amplifier based on the most modern circuit design of the tube age: the CIRCLOTRON amplifier, also known as PPP amplifier (parallel push pull).
With the SOMBETZKI S 509, we have created a modern tube amplifier whose sound can be described in the best sense neutral, detailed, sound-rich, fast and powerful. The spatial representation and airiness of the musical performance is breathtaking and authentic.
SOMBETZKI S 509 is equally well-suited for operation on conventional loudspeakers as well as dipole loudspeakers.

SOMBETZKI S PRE
now as tube amp available
In addition to the S 509 mono power amplifiers we offer the S PRE preamplifier. S PRE is offered both passive and active preamplifier S PRE A. In the passive version there are no active, i. e. reinforcing components installed. The active version additionally contains a high-level amplifier in tube technology.
Advantages of passive preamplifier:
Advantages of passive preamplifier:
- no sound distorting components in the signal path; the gain of the output stages is sufficient to provide a source signal, e.g. from the CD player, streamer, etc. to the final power.
- Investments were made in a high-quality 48-stage volume control, which is driven by remote motor control unit. No abrasive contact degrades the sound quality of the sensitive music signal.
- especially quiet audio sources (e. g. Apple mobile devices, older tuners or tape recorders) can be adjusted to the desired volume.
- long cinch cables (up to 15 m) to the power amplifiers or active loudspeakers can be connected without any problems.
- Manual source selector for 4 source devices
- Two volume-controlled RCA output pairs for connecting subwoofers or other power amplifiers
- Dimmable display by remote control; display can also be switched off
- Remote volume control (48 steps); driven by stepper motor
- WBT nextgen™ RCA jacks for all inputs and outputs
- 4 electron tubes E88CC for amplification, one rectifier tube EZ81 ( S PRE A only)
- Gain: 20 dB = 10-times (S PRE A only )
- Solid aluminum housing
- Housing color: Front panel in natural aluminum or black, other housing parts black anodised
- Dimensions: 150 x 160 x 320 mm (w * h * d)
- Weight: 3.5 kg net without packaging
- Price: from 2198 € / passiv
- from 3198 € / activ
