Worldwide Unique Amplifier Technology
for the highest listening pleasure:

11/4/07 Dipl.-Ing. Frank Blöhbaum 2
Worldwide unique: structure of the TEM 3200:
100% symmetrical PP- Hybridamplifier with
DC-coupling of all stages

11/4/07 Dipl.-Ing. Frank Blöhbaum 3
TEM 3200:
Only ONE high-power n-channel MOSFET per circuit leg

no matching problems

homogeneous signal processing of both half-waves

Widely overdimensioned transistor: 800W and 300A (!!)
= highest linearity and reliability

11/4/07 Dipl.-Ing. Frank Blöhbaum 4
TEM 3200:
Local linearisation of the MOSFET with special tube circuit

Harmonious unification of the advantages of both tube
and transistor technology

unique circuit: DC-coupled Triode and MOSFET with local
linearisation = allmost distortion-free output stage

11/4/07 Dipl.-Ing. Frank Blöhbaum 5
TEM 3200:
Well controlled current flow through both MOSFETs
during both half-waves

No zerocrossing or switching distortion

Characteristic of a Class-A amplifier combined with
Class-AB efficiency

Wonderfull combination of cleanliness and transparency
with musical flow and emotion

Roy Gregory from HiFi+: „The best amplifier on this planet
for conductors, composers, sound engineers and all
other people which are working seriously with music“.

Poweramplifier TEM 3200:
The consistent realisation of the new Blöhbaum System™
circuit technology yields many more advantages:

Symmetrical slew-rate and excellent settling behaviour
guarantee perfect reproduction of explosive dynamic music

Due to the circuit principle, extremely high damping factor

Outstanding control of allmost any loudspeaker load

Extremly low distortion, noise and hum

Self-cancellation of high (speaker-) current induced magnetic
fields

High output power combined with compact dimensions

11/4/07 Dipl.-Ing. Frank Blöhbaum 7
Preamplifier TEP 3800:
The Blöhbaum System™ circuit technology offers additional
advantages for preamplification as well:

All-tube output stage with sensational low output impedance
of less than 1 Ohm (!!) : Allmost distortion-free driver for
long and high capacitive cables

Equal distribution of (very low) spectral components
independent of signal level

Extremly low distortion, noise and hum

100% DC-coupling of all 6 tubes per channel:
perfect reproduction of highly dynamic music
with all details and emotions

TEM 3200 - The Poweramplifier
TEP 3800 - The Preamplifier

both incorporating the worldwide exclusive
Blöhbaum System™ circuit technology for the
wonderful combination of control and
transparency with musical flow and emotion.
A fascinating experience
