Die Modelle A-77X und A-88X waren die damaligen Elite-Verstärker der Pioneer-Serie, wobei der A-88X die Serie ausstattungs technisch und auch leistungs technisch angeführt hat. Die Geräte sind wohl aus den Vorgängern A-60 bis A-80 entstanden, die recht ähnliche Daten aufweisen.
 +
Alle Modelle (ab dem A-66X) verfügen "natürlich" über Metallfronten und Reglern aus Metall. Der Lautstärkeregler des A-88X und A-77X ist komplett aus Metall und wird mit einer Madenschraube an der Poti Achse befestigt.

== Reports ==
 
* Report in "FonoForum" 3 / 1986
 
 
 
  
* The models A-77X and A-88X were the elite amplifiers of the Pioneer series at that time, with the A-88X leading the series both in terms of equipment and performance.
+
Die Innenansicht mit sehr starker Ähnlichkeit zu der des A-88X:
* The units probably evolved from their predecessors, the A-60 through A-80, which had fairly similar specs.
+
http://img508.imageshack.us/img508/5940/innenansicht3ho.jpg
* All models (starting with the A-66X) "naturally" have metal fronts and knobs.
 
* The volume knob of the A-88X and A-77X is completely made of metal and is fixed to the potentiometer axis with a grub screw (on later A-77X, however, the knob is just plugged onto the corrugated axis of the potentiometer).

Rechts sieht man die abgeschirmte Phonoplatine.
  
'''Repair Note:'''
+
Die Front ohne Frontblende mit den Bedienelementen:
* If the red LEDs are no longer lit and the green ones are only dimly lit, then the power bulb in the green rubber above the main switch has probably burned out (12V , 0.1A).

It is located as a "series resistor" in front of the series regulator, which supplies the other displays with voltage.
