 +
* weiß leuchtender Power-Level-Indikator,
 +
** Anzeige-Bereich von 0,003- 100 Watt bei 8 Ohm, (links-rechts getrennt), (und auf Tastendruck 1/ 100)
 +
* 1x mittig einrastender Blance-Schieberegler

 +
* Boxenanschluss: 2 paar 8 - 16 Ohm, 1 paar 4 Ohm
  
'''Special feature:'''
+
== Bemerkungen ==
* with SEA you can also change the sound of the tape recording,
+
* Fernbedienung: nein, (auch '''kein''' Compu-Link)  
* white glowing power level indicator,
+
* gut geeignet für Bandmaschinen mit Hinterbandkontrolle
** display range of 0.003- 100 watts at 8 ohms, (left-right separated), (and at the push of a button 1/ 100)
+
* zu diesem Verstärker passt technisch und vor allem '''optisch''' der Tuner [[JVC T-X 200 L]]
1x centre-locking blance slide control
 
* Loutness switch: yes, (at -30 dB 100 Hz= + 6 dB, and at 10 khz= + 4 dB)

== Remarks ==
+
== Berichte ==
* buffer capacitors: 2x 10,000 µF (63 V)
 
* remote control: no, (also '''no''' Compu-Link)
 
* well suited for tape machines with rear tape control
 
* headphone output hidden behind a flap (bottom left)
 
* to this amplifier fits technically and especially '''optically''' the tuner [[JVC T-X 200 L]]
 
* ''Conclusion: still runs great today, also no scratching pots, solid workmanship.''
