Viele Teile, wie das gesamte Laufwerk können vom Sony JA30 ES verwendet werden. Gilt auch für das Display, Potis, klick Schalter. Im Prinzip ist das gesamte Frontpanel, sowie die Steuer Platinen (Laufwerk Steuerbord etc.) identisch mit dem Sony JA30 ES. Der Aufbau vom Sony JA50 zum Sony JA30 ES ist fast Identisch bis auf die getrennte Stromversorgung. Du ein paar Kleinigkeiten wie an manchen stellen Kupfer schrauben anstatt Metallschrauben. Alle Steuerkabel Motor Platinen Verbindungkabel sind identisch. Der Sony JA50 ES ist Materialistischer aufgebaut vom Gehäuse und andere Kleinigkeiten wie Schaumstoff zwischen den Tasten und LED...

Der JA50 ES sowie der JA 30 ES, beide lassen sich hervorragend mit neuerer OPA Technik umbauen. Hierzu müssen auf der Audio Platine  (DA>AD sowie Rekord Analog > Digital) Platine die jeweils 8 Operationsverstärker JRC2114D getauscht werden, gegen TI OPA2604 von Burson und Braun BB. Link: http://www.ti.com/product/OPA2604 (Achtung die untere Audio Platine vom JA50 ES ist mit den der 30 Serie nicht identisch) Beim Sony JA50 ES sind die OPA2604 sowie der OPA 2132AP schon von hause aus verbaut. Diese Chips sollte man nach 20 Jahre aber Tauschen gegen neue mit der identischen Bezeichnung.... Das Ergebnis ist Phänomenal und kaum zu glauben, Klanglich nicht wieder zu erkennen mit einem enorm hohen Auflösungsverhalten und einen super SAUBEREN und Dynamisch Präzisen Klang!!!  TI (BB) scheint die Chips im Laufe der Jahre überarbeitet zu haben. Alternativ lassen sich auch die OPA LM4562 NA (http://www.ti.com/lit/ds/symlink/lm4562.pdf) sehr gut einbauen, diese Chips haben nochmals einen höheren Dynamic umfang und rauschen weniger.
